Engineer's Report
No. 18 MUnicipal Drain
1995
Township of Bruce
1.0 PORWARD
1.1 Authorization
The Township of Bruce authorized the preparation of this Report,
in accordance with Section 4 of The Drainage Act, in a letter of
instruction from Deputy Clerk-Treasurer Roberta Trelford dated
August 31, 1994.
1.2 Objective
The objective of this Report is to provide an underdrainage
outlet for Lot 13, Concession 14, and the north part of Lot 13,
Concession 13 through Lots 11 and 12, Concession 14, all in the
Township of Bruce. This Municipal Drain will consist of
approximately 1420 metres of concrete drain tile and the
ditchbottom only cleanout of approximately 110 metres of the
ditch alongside Sideroad 10-11.
1.3 ACknowledgements
Maitland Engineering Services Ltd. wishes to acknowledge the
assistance and cooperation of the landowners involved with this
project, the Township Council members, the Road Superintendent,
the Clerk-Treasurer, and Township Office Staff.

2.0 INTRODUCTION
On August 10, 1994, the Township of Bruce received a petition,
signed by the OWner of Lot 13, Concession 14 and Pt. Lots 11, 12,
and 13, Concession 13, requesting an underdrainage outlet for
this property through Lots 11 and 12, Concession 14 to the
roadside ditch of Sideroad 10-11.
An on-site meeting for this proposal was held on November 7,
1994. At that time, the Owner of Lots 11 and 12, Concession 14,
indicated that he felt a drain was required to conduct the
underdrainage waters from Lot 13, Concession 14 and the north
part of Lot 13, Concession 13 through his properties to outlet at
Sideroad 10-11. The petitioner was in agreement with this
proposal and had signed the Petition for that purpose. The
upstream landowners, that is the owners of Lots 14 and 15,
Concession 14 and Lot 14, in Concession 13 indicated that they
had no need for a drain to conduct either underdrainage or
surface waters from their properties and were requesting that
they be excluded from the proposal.
At present, there are three underdrainage headers that outlet at
the line between Lots 12 and 13, Concession 14, into existing low
runs or swales that converge at approximately the midpoint of Lot
12 to form one large swale; this swale then travels in a westerly
and northerly direction through the remaining portion of Lot 12
and Lot 11 to outlet at Sideroad 10-11. It was suggested that an
outlet drain be installed north of the existing low runs
extending to the fenceline between Lots 12 and 13 at each
location where an existing header outlets.
After a brief site investigation, it was agreed to survey the
existing low run and proceed with a preliminary design. This
route was surveyed on November 7th, 1994 and proved feasible and
is proposed in this Report. Drawing MD231-1 indicates this route
and the lands affected thereby. The Profiles, Drawings MD231-2,
-3, and -4 and the specifications indicate the grades,
dimensions, and other particulars of the work. It should be

noted that this proposed drain is designed to provide
underdrainage outlet ONLY for Lot 13, Concession 14, and the
north part of Lot 13, Concession 13. Also included in the design
is approximately 6.4 hectares of Lots 11 and 12, Concession 14
which consist of a strip of land approximately 22.5 metres in
width on either side of the proposed drain and its branches; the
reader is asked to consult drawing MD231-1 for the affected area
that is included in this drainage proposal.
Further site meetings were held on March 29, 1995 and May 30,
1995.
3.0 LOCATION
The Township of Bruce is located on the extreme west side of the
south half of the County of Bruce and is bordered on the north by
Bruce County Road 11, on the south by Bruce County Road 15, on
the west by Lake Huron, and on the east by Bruce County Road 1.
The Village of Tiverton is located at the southwest corner, while
the Hamlet of North Bruce is located at the northwest corner of
the Township, and the Hamlet of Glamrnis is located in the extreme
southeast corner. The subject drain is located in the northwest
corner of the Township, approximately 2.5 km southeast of North
Bruce, immediately south of Bruce County Road 11.
As indicated on Drawing MD231-1, the watershed boundary includes
the middle portion of Lot 11 and the majority of Lots 12, 13, and
14, Concession 14, as well as the northerly portions of Lots 13
and 14, Concession 13. However, the "affected area" of this
drain includes only those lands in Lot 13, Concession 14 and Lot
13, Concession 13, as well as the 6.4 hectares in Lots 11 and 12,
Concession 14 being a 45 metre strip along the proposed route of
the drain and its branches.
The outlet for the tile portion of this proposed Municipal Drain
is the north roadside ditch of Sideroad 10-11. The eventual
outlet for this Municipal Drain is Mill Creek which is located in
the extreme northeast corner of Lot 10, Concession 14.

The reader is asked to consult drawing MD231-1 for the exact
location of the watershed boundary and the "affected area" for
this drainage project.
4.0 THE DRAINAGE ACT, R.S.O. 1990
As this is a new Municipal Drain, this Report is being prepared
in accordance with Section 4 of The Drainage Act.
5 . 0 AREA REQUIRING DRAINAGE
At the November 1994 on-site meeting, the area requiring drainage
was determined to consist of Lot 13, Concession 14, and the north
part of Lot 13, Concession 13. Since the Owner of that property
had signed the Petition, the petition was considered to have met
the requirements of Section 4 (1) (a) of The Drainage Act and was
deemed to be valid.
6 . 0 DRAINAGE AREA
The reader is asked to consult drawing MD231-1 which illustrates
the extent of the drainage area as well as the "affected area"
for this drainage proposal. Some additional information is
provided under the following headings.
6.1 Extent
The "affected area" of this Municipal Drain is comprised of
approximately 40.5 hectares of Lot 13, Concession 14, approxi-
mately 8.9 hectares of Lot 13, Concession 13, and approximately
6.4 hectares of Lots 11 and 12, Concession 14, which is a 45
metre wide strip along the length of the proposed drain and its
branches. The areas of each lot are shown on Drawing MD231-1 and
are tabulated in the Schedule of Assessments, Appendix C.
6 .2 Boundary
The watershed boundary is indicated on the enclosed Plan and has
been established as part of the work undertaken in preparing this
Report. To establish this boundary, aerial photographs were
reviewed, field inspections were undertaken, and the Ontario Base
Mapping was reviewed.

6.3 Soils
The Bruce County Soils Map indicates that Elderslie silty clay
loam, a lacustrine soil with imperfect natural drainage, is the
predominant soil in the "affected area". In addition, a narrow
band of Chesley silty clay loam, a lacustrine soil with poor
natural drainage, bounds the low runs along which the proposed
Drain and its branches are to be installed. Elderslie silty clay
loam has an agricultural capability rating of 70% Class 1 and 30%
Class 2 with topography as the limitation.
6.4 Test Holes
Test holes were dug prior to preparing this Report and the
results have been included herein. Should significant interest
be indicated at the time of tendering, further test holes may be
dug at that time.
6.5 Shape
This drainage area is somewhat rectangular in shape, except for
the portion in Lots 11 and 12, which follows the meandering low
runs.
6.6 Topography
The majo;-ity of the "affected area" is gently sloping to
undulating; however, in spite of the topographic limitation of
the Elderslie silty clay loam, none of the subject lands in Lots
13, Concession 13 and 14 are too steep to restrict agricultural
operations. Adjacent to the low runs in Lots 11 and 12, some of
the topography is quite steep.
6.7 Land Use
The majority of the land within the "affected area" is privately
owned and used for agricultural purposes, namely the production
of cash crops such as corn, grain, and beans. A small portion of
bush exists in the extreme southeast corner of Lot 13, Concession
14. The affected area in Lots 11 and 12 is used exclusively for
intensive pasturing.

7.0 PRESENT CONDITIONS
Underdrainage water from Lot 13 now outlets onto the ground surface
at three locations on the east side of Lot 12 and the flows
westerly and northerly, through Lots 12 and 11, into the east ditch
of Sideroad 10-11. These three flow routes converge at the'
midpoint of Lot 12. Surface water also flows through these low
runs but has not been addressed in this proposal as it is not of
concern to the Owner of Lots 11 and 12.
8.0 DESIGN CRITERIA
The applicable sections of "Design and Construction Guidelines for
Work Under The Drainage Act", as prepared by the Government of
Ontario, and the applicable sections of "Drainage Guide for
Ontario", as published by the Ontario Ministry of Agriculture and
Food, have been used for the design of this Municipal Drain and
will be used for the construction as well. A drainage co-efficient
of 12.7 rom or one half inch in 24 hours has been used to determine
the underdrainage outlet requirements. It should be noted that NO
ALLOWANCE FOR SURFACE WATER DRAINAGE HAS BEEN MADE IN THIS DESIGN.
9.0 DESIGN CONSIDERATIONS
In addition to the normal items considered when designing a tile
Municipal Drain, the following special items were considered for
this project.
9.1 Soil Conditions
As a result of the subsurface soil conditions along the entire
route of the proposed drain, concrete drain tile is proposed to be
used for the closed part of this Municipal Drain. The reader is
asked to consult the test hole results for details concerning these
soil conditions.
9.2 Drainage Route
As previously indicated, significant low runs exist through Lots 11
and 12. It is proposed to install the new Municipal Drain
generally to the north of these low runs. Crossings of these low
runs shall be kept to a minimum.

9.3 Underdrainage Allowance
As previously indicated, the majority of the "affected area" for
this Municipal Drain is Lot 13, Concession 14, and the north part
of Lot 13, Concession 13. This design area has been used for
sizing the proposed concrete drain tile. Also as indicated
previously, an allowance for apprqximately 6.4 hectares of Lots
11 and 12 has been included in the design. This 6.4 hectare area
is composed of a 45 metre wide strip extending along the entire
length of the new Municipal Drain. This allowance has been
incorporated into the design to provide for underdrainage of the
low wet land adjacent to the proposed Municipal Drain and has
been agreed to by the owner of Lots 11 and 12.
10.0 PROPOSED WORK
The work proposed under this Report has been divided into three
parts, a Main Drain and Branches A and B. These are described
separately, as follows. All tile will be installed with a wheel-
type trencher, generally on the north side of the respective low
run.
10.1 New Drain
The Main Drain portion of this No. 18 Municipal Drain is proposed
to consist of approximately 150 metres of ditch alongside
Sideroad 10-11 (110 m of which will be excavated), 6 metres of
400 mm diameter corrugated steel outlet pipe with riprap,
approximately 1030 metres of 350, 300, 250, and 200 mm diameter
concrete drain tile, and four junction boxes. This tile will
follow the south low run to the east side of Lot 12.
10.2 Branch A
This Branch Drain will service the north low run and will consist
of approximately 280 metres of 200 mm diameter concrete tile and
one junction box.
10.3 Branch B
This Branch Drain will consist of approximately
mm diameter concrete tile and one junction box.
the middle low run on the east side of Lot 12.

10.4 Purther Details
Complete details of the proposed work are included in Appendix B
- Cost Estimate and the Special Information to Tenderers included
with this Report. The reader is asked to consult these for
further information regarding the various sections of the Drain.
It is not anticipated that any unknown existing tiles will be
encountered; however, should such tiles be found, they will be
reconnected to themselves or to the new Drain as determined by
the Engineer at the time of construction.
10.5 General
The construction work described in this Report is that which is
proposed at the time of writing; however, if unforseen
circumstances are encountered after the preparation and adoption
of this Report, the Engineer may institute Change Orders, as may
be required, in order to have the works properly constructed.
11.0 ENVIRONMENTAL CONSIDERATIONS
Since all of the proposed work will be undertaken on pastured
land and since the new drain will be installed using the
trenching method, it is not anticipated that this project will
create any significant adverse environmental effects. Sediment
control will be undertaken where necessary.
12.0 APPENDICES
Three appendices are attached hereto and form part of this
Report, namely Appendix A - Allowances, Appendix B - Cost
Estimate, and Appendix C - Assessments.
12.1 Appendix A - Allowances
In accordance with Sections 29 and 30 of The Drainage Act, this
Appendix includes allowances for right-of-way and for damage to
lands for the portions of Lots 11 and 12, Concession 14 upon
which the work is to be undertaken.

12.2 Appendix B - Cost Estimate
This Appendix provides a detailed estimate of the cost of the
proposed work including all materials, construction,
administration, and allowances.
12.3 Appendix C - Assessments
This Appendix is the distribution of the total estimated cost
over the lands and roads involved. These assessments are made in
accordance with Sections 22 and 23 of The Drainage Act. All
affected private lands are agricultural within the meaning of The
Act and, therefore, should be eligible for any grants which may
be available from the Ministry of Agricultural, Food, and Rural
Affairs.
13.0 MAINTENANCE
The sections of The Drainage Act dealing with obstruction of,
damage or injury to, and pollution of a Municipal Drain, namely
Sections 80, 82, and 83 are brought to the attention of the
landowners. As can be seen from these sections, the landowners,
as well as the Municipality have responsibilities to ensure that
a Municipal Drain is properly maintained and not abused. Proper
maintenance of the proposed works described herein will be
necessary to ensure that all parts continue to function properly.
This maintenance should include regular inspection and necessary
work along the entire length of the drain. These proper
maintenance procedures should ensure that the junction boxes
remain unobstructed by debris or sediment and are cleaned on a
regular basis. As well, any areas of washout or settlement
should be attended to immediately. Landowners involved with this
drain should make regular inspections of the portion on or
adjacent to their properties and should report any problems to
the Township so that proper action can be taken by the Township
Drainage Superintendent.
Normally, it is recommended that no lateral drains be connected
to a new Municipal Drain, but rather that headers or main drains
be constructed on each side and connected at the junction boxes
~ ,1

along the route of the Municipal Drain. However, in this
particular case, since only a narrow width of Lots 11 and 12 has
been included in the affected area, two sets of connections will
be allowed to the Main Drain downstream of Station 0+662.
However, upstream of that point, and on the Branches, connections
shall be made only at the junction boxes. All connections must
be made very carefully, especially those being tapped directly
into the concrete tile.
After this Municipal Drain has been constructed, the Township of
Bruce shall be responsible for the maintenance thereof.
Maintenance costs incurred in the future shall be distributed in
accordance with the terms of The Drainage Act using ONLY THE
OUTLET PORTION OF THE ASSESSMENT SCHEDULE IN APPENDIX C. The
Township Road Authority shall be entirely responsible for the
cost of future maintenance of the roadside ditch along Sideroad
10-11.
This shall be the method of proportioning maintenance costs for
the subject Municipal Drain until such time as it is varied in
accordance with The Drainage Act.

UNDERSTANDING DRAINAGE ASSESSMENT
(Revision of Factsheet. "Understanding Drainage Assessment;" May 1976)
Sid Vander Veen, P. Eng. Resources Management Branch
The Drainage Act provides a legal procedure by which an
"area requiring drainage" may have an outlet drain con-
structed to dispose of excess water.
The drainage worl< is initiated by interested individuals
within an "area requiring drainage" who will benefit from
the construction of the drain. A petition fonn. obtained from
the municipal clerk. is signed by interested landowners. In
order to be valid or sufficient, the petition must be signed by
the majority of the owners in the "area requiring drainage"
or by owners that represent at least 60% of the lands in this
area. The "area requiring drainage" is usually described by
lot and concession, or other legal land description. By tak-
ing this action. it is presumed that the owners signing the
petition have made a decision that the drain will be of bene-
fit to them and that the probable cost will be lower than the
anticipated benefits. The initial benefit-cost decision is
made at this point by the landowners. not the engineer or
Council.
The petition is presented to and considered by Council.
If the petition represents a proper "area requiring drainage",
that is a real drainage basin. and appears to be valid, the
Council may decide to proceed. Council then notifies each
of the petitioners of this decision as well as any other munic-
ipality affected and the local Conservation Authority and the
Ministry of Natural Resources.
Council then appoints an engineer. The engineer is an
employee of Council, hired to design this specific drain.
Under The Drainage Act, Section 9(2), the engineer is
required to hold an on-site meeting to detennine (I) the area
requiring drainage, (2) if the petition is valid. (3) the
drainage needs of the area. The engineer is then required "to
make an examination of the area requiring drainage as
described in the petition and to prepare a report which shall
include,
(a) plans, profiles and specifications of the drainage
works;
(b) a description of the area requiring drainage;
(c) an estimate of the total cost thereof;
(d) an assessment of the amount or proportion of the
cost of the works to be assessed against every parcel
of land and road for benefit. outlet liability and injur-
ing liability;
(e) allowances, if any, to be paid to the owners of land
affected by the drainage works and
(f) such other matters as are provided for under this
Act."
The engineer's report is presented to Council, who then
notifies all persons assessed and calls a special meeting
where the report is considered. General objections to the
report may be raised at this time. At this meeting signatures
may be added or removed from the petition and this deter-
mines if the project will continue. Unresolved problems,
depending on the subject. may be appealed to the Court of
Revision, the Ontario Drainage Tribunal or the Drainage
Referee. Details on appeal procedures may be found in The
Drainage Act* or in Ontario Ministry of Agriculture and
Food Factsheet, Drainage Legislation.
The engineer's report includes two important items:
I. The estimated cost of the worl<: No matter how indi-
vidual assessments are amved at, this total estimated
cost must always be equal to the total amount
assessed, otherwise the work cannot proceed.
2. The assessment liability: This may be spread over
several pages if an owner owns several parcels of
land and if there are branch drains. It may be sum-
marized.
Let us examine the obligations regarding this assess-
ment.
Responsibilities Under Common Law
A natural watercourse is defined generally as a stream of
water which flows along a defined channel, with bed and
banks. for a sufficient time to give it substantial existence.
This may include streams that dry up periodically.
A riparian landowner (owner of lands that abut upon a
natural watercourse) has the right to drain his or her lands
into the natural stream, but may not bring water in from
another watershed. He or she can collect water in ditches
and drains and discharge it into the watercourse even though
it results in an increase in volume and rate of flow.
Where a natural watercourse becomes a pan of a drain. it
is no longer a natural watercourse. When this occurs, the
riparian rights. as described earlier. are lost.
Surface water not flowing in a natural watercourse (i.e.
not having discernible bed and banks) has no right of
drainage; an owner of lower land may, at his or her own
choice. either allow the water from higher land to flow over
it or by dams or banks, keep such water off his or her prop-
* The Drainage Act may be found in the Revised Statutes of
Ontario 1980, Chapter 126. available in most public libraries.
Individual copies may be purchased from the Ontario Government
Bookstore. 880 Bay Street. T oronlo.
erty. No owner has the right to collect such surface water by
ditches or drains and discharge it on lands of another. He or
she has a responsibility to take this water to a sufficient out-
let, i.e., a natural watercourse or a drain constrUcted under
The Drainage Act. '
Since there is no right to drain surface water, the owner
of each parcel of land in the watershed is generally assessed
for "outlet liability". In other words, his or her Common
Law liability is removed by paying for the increased size or
cost of the drain due to the volume of water which is dis-
charged from his or her property. even though the drain may
not provide a direct outlet for this water. The authority for
this liability is set out in Section 23(1).
Since, through Common Law, a landowner is also liable
for any damage he or she may cause from water which he or
she collects in drains and discharges on other land without a
sufficient outlet, he or she may be assessed for relief from
such "injuring liability" if the new drain serves as an outlet
for his or her drains and prevents this injury from occurring.
The authority for this liability is set out in Section 23(2).
Injuring liability is frequently difficult to distinguish from
outlet liability, consequently many engineers' reports do not
contain such an item.
The assessment for outlet liability and injuring liability is
based on the volume and rate of flow of the water artificially
caused to flow from an owner's property. Generally, the
assessment is based upon a unit value per hectarage.
Owners at higher elevations on a watershed may have a
higher unit charge than those owners near the outlet since
the water from their land makes use of a greater length of
drain. A difference may be made in the unit outlet charge
due to varying types of soil or land use. or the distance to the
drain.
Responsibility Under The Drainage Act
In addition to the Common Law responsibility, an owner
may also be assessed for benefit.
Benefit will vary between different lands, according to
their differences of elevation, quantity of water to be drained
from each, distance of undrained land from the course of the
proposed ditch, and the presence or absence of existing
drains, and other like factors.
To consider whether a parcel of land will receive any
benefit from the construction, it is proper to consider
whether any enhanced fmancial value will accrue to it as a
result of the drain construction. This may occur through the
increased productive power of the land or by rendering it
mOre saleable and at a better price, or by preventing water
from entering on to it.
If the proposed drainage works can be of no possible ben-
efit to the owner. or is of no commercial or agricultural
value, the Act does not authorize a contribution for benefit.
Sometimes, an owner has an undeveloped area that he or
she intends to leave in this condition. The owner may feel
that he or she should not be assessed since the drain will be
of no benefit. However, the property could change hands
and the new owner might want to drain and develop it. It is
with this in mind that the engineer must make an assess-
ment, regardless of the present owner's intentions.
It is the duty of the engineer to detenoine whether or not
a parcel of land will benefit from the project. When
appealling a benefit assessment, the landowner must prove
that the land has no benefit from the drain.
. '
... An ~wner has no responsibility for work done upstream
from his or her property unless the work provides a benefit
by "cutting off" a harmful flow of water across the property.
In some instances, a "special benefit assessment" may be
levied against the property. This value usually represents
the difference in cost between that which was originally
designed and the increased level of design requested by a
landowner. For example, a closed or tile drain where open
ditches would ordinarily suffice, or the construction of
ponds beside the drain, or other special requests by a
landowner specifically for this benefit. The authority for
this liability is set out in Section 24.
Engineer's Report
The Engineer's report should contain a plan and profile
of the drain, as well as details on the drain design and the
assessment schedule.
The plan shows the location of drains and the limits of
the watershed. The profile shows ground elevations along
the drain and the present and proposed drain bottom. The
specifications give details on how the drain is to be con-
structed_
The Schedule of Assessment contains several columns.
The first group contains the names of owners with a descrip-
tion of each parcel of land assessed.
The hectarage shown in the schedule for which an owner
is assessed is only approximate. No survey is made to accu-
rately establish the watershed boundary or farm areas. Any
minor error in hectarage assessed is not a valid basis for
appeal nor does it greatly affect the assessment. The other
columns in the Schedule set forth the assessment liability for
each drain and/or branch drain. These values are only esti-
mates. The final value will not be known until the constrUc-
tion work is finished. The assessment will then be prorated
to recover the actual cost.
Allowances to lands injured by the work are set out in a
separate schedule by the engineer. Authority for this is
Sections 29 to 33 of the Drainage Act.
Damage to crops during construction and disposal of
waste material will vary with the time of year the work is
constructed. Crop damage due to spreading the spoil on the
banks is based on a decreasing yearly loss of crop over sev-
eral years. All or part of the cost of access bridges from a
public road to the property may be assessed to the property
owner.
Farm bridges are constructed as a part of the work. In
certain circumstances a severance allowance may be paid
instead of building the bridge. The allowance will depend
upon the value of the land severed, or the cost of the bridge
that would be required. The cost, or part of the cost of farm
bridges or the severance allowance may be assessed against
the property.
Where private drains are incorporated into the new drain,
a nominal allowance may be paid based on any saving that
may result from using the private drain. These allowances
may not be included in the Summary of Assessments but are
usually shown in a separate Schedule of Allowances.

SECTION B - INFORMATION TO TENDERERS
B. 1 INFORMATION TO TENDERERS TO APPLY
This section, Information to Tenderers, shall form part of the
Contract Documents and the information herein shall apply unless
superseded by Section A, Special Information to Tenderers.
B. 2 TENDERING SUBMISSION
Each tender shall be submitted in its entirety and in accordance
with the Special Information to Tenderers. It shall include a
fully completed Form of Tender as bound herein. The complete
written Tender Documents must be submitted as a tender, and the
Form of Tender must remain bound with the other documents. The
Form of Tender is provided in Duplicate and the Tenderer may
retain one set for his records. All sections of the Form of
Tender shall be completed.
B. 3 WITHDRAWAL OR QUALIFYING OF TENDERS
A tenderer who has already submitted a Tender may submit
Tender at any time up to the official closing time.
Tender received shall supersede all Tenders previously
by that Tenderer.
A Tenderer may withdraw or qualify his Tender at any time up to
the official closing time by submitting a letter bearing his
signature and seal as in his tender to the point of tender
delivery where the time and date of receipt will be recorded and
the letter placed with the other tenders. No telegrams or
telephone calls will be considered.

submitted
B. 4 INFORMAL OR UNBALANCED TENDERS
Tenders which are incomplete, conditional, illegible, or obscure,
or that contain additions not called for, reservations, erasures,
alterations, or irregularities of any kind, may be rejected as
informal.
Tenders that contain prices which appear to be unbalanced so that
they likely would adversely affect the interests of the Owner,
may be rejected.
Tenders that are based upon an unreasonable period of time for
the completion of the works may be rejected.
- Bt -
"
,
Wherever in a tender the amount tendered for an item does not
agree with the extension of the estimated quantity and the
tendered unit price, the unit price shall govern. The amount
and the Total Tender Price shall be corrected accordingly.
The Engineer reserves the right to waive formalities at his
discretion.
Tenderers who have submitted tenders that have been rejected by
the Engineer because of informalities will normally be notified
of the reasons for the rejection within fourteen days after the
closing date for tenders.
B. 5 DISCREPANCIES IN AND INTERPRETATION OF TENDER DOCUMENTS
Should a Tenderer find discrepancies in, or omissions from any
part of the tender document, or should he be in doubt as to its
meaning, he should notify the Engineer who may send written
instruction to all Tenderers.
No oral interpretation shall be made to a Tenderer as to the
meaning of anything within the tender document. Addenda shall be
issued by the Engineer to items in the tender as he determines.
Addenda shall be in writing unless time prohibits mail delivery
prior to tender closing.
B. 6 QUANTITIES ARE ESTIMATED
The quantities shown for the items in the Form of Tender are
estimated only and are for the.. sole purpose of indicating to
Tenderers the general magnitude of the work. For any work done
or materials supplied on a unit price basis, the Contractor will
be paid for the actual measured quantities at the respective unit
prices tendered.
The Engineer has the right to increase or to reduce the
quantities required or to suspend or omit any item or portion of
the work at any time as he may deem advisable.
The Contractor shall not be entitled to any compensation neither
for loss of anticipated profit nor for removal or the bringing in
of materials as a result of the deletion or of the addition of
any item or part of an item from the Form of Tender.
B. 7 PRICES TENDERED
The unit prices or lump sum bid shall include all labour,
equipment and materials necessary for the construction of the
items specified, in complete conformance with the standards of
work and materials specified, as set out in the applicable
sections of this Contract.

B. 8 ACCEPTANCE OR REJECTION OF TENDERS
The Engineer shall not be responsible for any liabilities, expenses,
loss or damage incurred, sustained or suffered by any Tenderer
prior or subsequent to or by reason of the acceptance or non-
acceptance by the Engineer of any tender or by reason of any
delay in the acceptance of a tender. Tenders are subject to a
formal Contract being prepared and executed.
The Engineer reserves the right to reject any or all tenders and
to waive formalities as the interest of the Owner may require
without stating reasons therefore and the lowest or any tender

No.30 General for Municipal Drains
F.30.1 SCOPE OF SPECIFICATION
This specification covers the general conditions governing the
construction of a municipal drain under the most recent revision
of The Drainage Act and amendments thereto.
F.30.2 BENCH MARKS
Bench marks shall be set at intervals along the course of the
work at locations shown on the accompanying plan and/or profile.
The Contractor shall be held liable for the cost of re-
establishing bench marks destroyed during the course of
construction. Attention is drawn to Section 13(2) of The
Drainage Act.
F.30.3 STAKES
Normally stakes are set 30 m apart throughout the course of the
work and at all fences. The Contractor shall be held liable for
the cost of replacing any stakes destroyed during construction.
The drainage area shall be held liable for the cost of replacing
any stakes destroyed prior to commencement of construction.
F.30.4 LINE
The drain shall run in straight lines throughout each course
except at intersections, where it shall run on a curve of 15 m
radius unless otherwise specified. If the work consists of the
improvement of an existing open drain, then the centre line of
the existing drain will be the centre line of the finished work
unless otherwise specified. The centre line of the ditch shall
be staked by the Contractor at least one complete course ahead of
the digging, and all sloping and widening necessary shall be done
in such a manner as to make the finished work uniform.
~ /
.. 'J
- 2 -
F.30.5 PROFILE
The drain is to be excavated to regular grade lines as shown on
the profile. These grade lines show the bottom of the finished
drain and are governed entirely by the bench marks. In the case
of tile drains, the grade line is that of the invert of the tile.
The profile shows, for the convenience of the Contractor and
others, the approximate depths from the surface of the ground to
the grade at the point where the numbered stakes are set and from
the average bottom of the present drain as taken at the time of
survey, however, the bench marks must govern the construction.
Open drains shall be brought to an even grade in the bottom so
that water will not stand therein. A variation of 20 mm from the
grade lines for tile drains shall be deemed sufficient reason to
cause the work to be rejected and done over.
F.30.6 CLEARING
Brush, timber, logs, stumps, boulders or other obstructions
located in or along the course of the work and any brush or
debris along the banks of a drainage works shall be removed a
sufficient distance to be clear of the excavation and the
excavated material, or to the widths shown on the page entitled
"Working Space". No brush or trees are to be left inside the
slopes of the drain whether they are located within the limits of
the excavation òr not. Brush cleared in accordance with the
above shall be piled in a,location and in a manner satisfactory
to the Engineer for burning by the Owner. Unless otherwise
specified or directed, brush piles shall be a minimum of lOO m
apart and shall contain only cleared material. The Contractor
will be permitted to cut standing timber along the course of a
works, to the extent that may in the opinion of the Engineer be
necessary to allow the safe and economical operation of the
excavating equipment. Timber so cut shall be left on the
property of origin for use of and disposal by the Owner.
F.30.7 FENCES
The Contractor will be permitted to remove fences to the extent
necessary to allow him to construct the drain and dispose of any
excess material according to specifications. Any such fences
shall be carefully handled so as to cause no unnecessary damage.
Such fences shall be replaced by the Contractor in as good a
condition as found. The Contractor shall supply all material
necessary to properly reconstruct any fences. The contractor
shall not leave any fence open when he is not at work in the
immediate area. Replacing of the fences shall be to the
satisfaction of the Engineer. The Contractor shall be deemed to
have met this specification when he obtains a statement in
writing signed by the Owners of the land affected to the effect
that the treatment of fences is satisfactory to them.

The drain shall have the full specified bottom width at the
specified grade line at the time of final inspection. Each side
of an open drain shall be sloped at 1 meter vertically to 2
meters horizontally, or as otherwise specified or shown on the
accompanying plan, profiles, and detail sheets. Each side of the
drain shall be smooth and have a uniform slope from top to bottom.
F.31.2 SPOIL BANK
A clear berm or margin of at least 2 meters shall be left between
the top edge of the open drain and the spoil bank. No excavated
material is to be left in any ditches intended to conduct water
into the open drain. In no case shall the side of the spoil bank
closest to the drain be sloped greater than 1.5 H to 1 V unless
otherwise specified.
F.31.3 EXCAVATED MATERIAL
Excavated material shall, in general, be placed on the lower side
of the drain or on the side opposite trees or fences. It shall
be deposited, spread and levelled to a maximum depth of 200 mm
and left in a manner such that the lands on which it is spread
may be cultivated with adjacent lands by use of ordinary farm
machinery. Material excavated in land which is timbered may be
spread to a maximum depth as specified on the profile or to a
maximum depth of 600 mm if not specified on the profile. The
Contractor is not responsible for the removal of stones or
boulders from the excavated material. Disposal of excavated
material shall be to the satisfaction of the Engineer.
F.31.4 SURFACE WATER INLETS
Surface water inlets to the drain shall be provided through the
levelled spoil on each property at intervals of 100 meters or at
locations as shown on the profile. No excavated material shall
be left in, or any damage done to a ditch, furrow, pipe, tile or
depression which is intended to conduct water into or across an
open drain.

F.31.5 ABANDONED CHANNEL
Excavated material shall be used to fill abandoned channels as
specified in the Special Information to Tenderers or on the
detail sheets.
F.31.6 FARM BRIDGES
All farm bridges shall have a m~n~mum opening equal to the cross-
sectional area specified in the report or on the profiles.
F31.7 FARM CULVERTS
If the owner, at the time of construction, has supplied a culvert
of the specified size at the site, the Contractor shall install
it as part of the work. The culvert shall be installed with the
invert 150 mm below the grade of the drain.
F31.8 EXCAVATION AT BRIDGE SITES
The excavation at bridg~ sites shall be to the full depth of the
drain and as nearly as possible the full width of the drain as
specified for the bridge location. The excavation at a bridge
site shall be made in a manner to protect the structural integrity
of any permanent bridge. A temporary bridge may be carefully
removed to allow excavation. The removal of said bridges is to
be done in such a manner so as to cause no unnecessary damage to
the bridge components. Temporary bridges removed to allow
excavation shall be replaced in as good a condition as found so
far as material allows. Replacing of such bridges shall be to
the satisfaction of the Engineer. The Contractor shall notify
the Engineer immediately it becomes apparent that excavating to a
specified grade will endanger any culvert or bridge. The
Contractor shall cease excavation at the bridge or culvert site
until the Engineer instructs him to proceed.
F31,9 SEEDING
Unless indicated otherwise in the Special Information to
Tenderers, the Contractor shall seed the newly excavated ditch
banks, with a seed mixture and at a rate approved by the
Engineer, at the end of each working day.
F31.10 SEDIMENT CONTROL
Unless indicated otherwise in the Special Information to
Tenderers, the Contractor shall install an approved sediment
control device at the downstream end of the open drain excavation
and shall remove any accumulated sediment therefrom after the
open drain work is completed. The sediment control device shall
also be removed at the completion of the work,

SECTION F
PROJECT SPECIFICATIONS
No. 32 Tile Drains
F.32.1 MATERIALS
All tile installed under these specifications shall be sound and of
first quality. Clay and concrete drain tile shall meet ASTM
Specifications as set out in Designation C4 and C498 for Clay Tile
or the latest revision thereof and/or C412 for Concrete Tile or the
latest revision thereof. Corrugated plastic drainage tubing shall
meet CGSB standard 41-GP-29 Ma, or the latest revision thereof.
Tile supplied by the Contractor shall be approved by the Engineer
prior to being incorporated in the work. The Engineer shall have
the right to order any tests he deems necessary to be performed on
the tile. All costs of such tests shall be borne by the
Contractor.
The Contractor shall be responsible for the unloading and placement
of all materials required for the municipal drain construction.
Such unloading and placement shall be undertaken in a manner
acceptable to the Engineer.
F.32.2 DRAIN GRADE
The grades for the tile drain shall be established and controlled
by laser grade control equipment mounted on the tile installation
machinery or in the drain trench.
F.32.3 TILE LAYING
All tile shall be laid carefully in a smooth bottomed trench. All
tile shall be laid together as tightly as possible. The maximum
allowable space between successive tiles shall be 6 mm. Each tile
shall be laid firmly on a solid bottom in the trench so that the
successive tiles align both horizontally and vertically. If a
wheel-type or chain-type ditching machine is not used to excavate
the trench for the tile, the Contractor shall, at his expense,
supply and install a layer of approved granular bedding material,
at least 150 mm in depth, on the entire trench bottom, prior to
placing the tile. The trench shall not be opened up for a distance
greater than 60 m in advance of the tile laying. The trench shall
have a maximum width at the top of the tile not greater than a
value equal to the outside diameter of the tile plus 225 mm. All
obstructions, dirt or foreign material shall be removed from the
inside of the tile prior to laying. Tile drains shall be con-
structed at an offset from and parallel to any existing ditch or
defined watercourse. The Contractor shall exercise care not to
disturb any existing tile drains which follow the same course as
the new drain.

F.32.5 MAIN TILES ENCOUNTERED
Any subsurface drain encountered by the Contractor when constructing
a municipal drain under these specifications, shall be either
reconnected or connected to the new drain being constructed, as
directed by the Engineer. The normal practice for reconnecting
existing tile drains, up to and including 150 mm diameter (6"),
will be to hand compact uncontaminated sub-base material from the
new trench bottom to the underside of the existing tile. After
adequate consolidation has been achieved, a perforated plastic
drainage tube of sufficient size to slide over the outside of the
existing tile shall be coupled over the existing tile. This
connection shall be made where the existing tile is sound. When
completing backfilling at such a location, the Contractor shall
take sufficient care to ensure that the new plastic drainage tubing
is not damaged. Any tile drains encountered which are larger than
150 mm diameter (6") may, if approved by. the Engineer, have their
upstream end connected to the new drain with suitable sized plastic
drainage tubing or equal material, and the downstream end of said
tile shall be plugged to prevent entry of foreign material into the
said tile.
The Contractor shall provide a unit price per connection in Section
C, Form of Tender, and said unit price shall include the supply of
all material labour and equipment necessary to make the said
connection(s~. Further, the Contractor shall notify the respective
landowner of any and all sub-surface drains encountered.
F.32.6 BACKFILLING
As the laying of the tile progresses, partial filling (blinding)
shall be made at the sides sufficient to hold the tiles securely in
place. After the work is inspected by the Engineer, the remainder
of the excavated material shall be used to restore and maintain the
natural surface of the ground. Care shall be exercised in
backfilling the trench to see that no stone or boulder capable of
damaging the tile is used in the backfill material adjacent to the
tile. In no case shall stones having a diameter greater than 150
mm be used in backfill material within 300 mm of the tile.
F.32.7 OUTLET PROTECTION
The outlet end of a tile drain shall consist of a length of riveted
corrugated steel pipe fitted with a rodent proof grating which is
hinged at the top to allow the exit of foreign material from the
tile.
Unless otherwise specified, the end of the corrugated steel pipe
shall be protected with hand placed riprap as specified by the
Engineer. The riprap shall extend from the bottom of the receiving
trench to the original ground surface and for a distance of at
least 2 m from the end of the outlet pipe.

(minimum) reinforced concrete. The sides and bottom shall be 114
nun (4 1/2") thick. The inside dimensions shall be 600 nun x 600 nun
(2' x 2'), and a 300 nun (1') sump shall be provided. Prefabricated
boxes meeting the aforementioned requirements may be used subject
to the Engineer's approval. Each J/B shall be placed such that the
top extends 150 nun (0.5') above the ground surface. With the
exception of DI/CB's all boxes shall have a plugged tile or blind
inlet the same size and elevation as the inlet (to a maximum size
of 300 nun (12"») placed in all sides not used by this drain.
Suitable grouting material (concrete, unless specified otherwise)
shall be placed around all tiles and/or pipes connected to the box.
Welded steel junction box tops or grates shall be constructed
of two pieces of 51 nun x 51 nun x 6 nun (2" x 2" x 1/4") angle iron,
connected by 32 nun (1 1/4) steel tubing at 76 nun (3") centers with
outside tubes 38 nun (1 1/2") from end of angle iron. The grate
shall be fastened to the structure using non-corrosive fasteners.
Buried junction boxes shall be constructed as described above with
the following exceptions: no sump required; bottom and sides shall
be 150 nun (6") thick; and top shall be 150 nun (6") thick concrete.
Post and sign type markers, similar to those supplied by Coldstream
Concrete Ltd., shall be supplied and installed at each junction box.
F.32.8 CATCHBASINS
Unless specified otherwise, catchbasins shall be constructed of 20
MPa (minimum) reinforced concrete with 114 nun (4 1/2") thick sides
and bottom, inside dimensions of 600 nun x 600 nun (2'x 2') and a
sump with a minimum depth of 300 nun (1'). Prefabricated basins
meeting the aforementioned requirements may be used subject to the
Engineer's approval. Each basin shall be placed such that the
inlet (or top) is at the elevation specified on the "Junction Box -
Catchbasin Details" sheet, and the exact field location of the
basins shall be approved by the Engineer. Where ditch inlet
catchbasins (DI/CB) are called for, the slope of the top shall be
2:1 unless specified otherwise.
Grates for flat top catchbasins (FT/CB) shall be of similar
construction to the grates specified for junction boxes (J/B) and
shall be fastened to the structure using non-corrosive fasteners.
Suitable grouting material (concrete unless specified otherwise)
shall be placed around all tiles and/or pipes connected to the
basin. The standard grate for a ditch inlet catchbasin (DI/CB)
shall be the three sided protruding type consisting of three
vertical sides, a flat top, and a bottom sloped to conform to the
slope of the top of the DI/CB. Ditch inlet gratings shall be
constructed from the same material as is specified for J/B tops.
Post and sign markers, similar to those provided by Coldstream
Concrete Ltd., shall be supplied and installed at each catchbasin.
Field stone riprap shall be placed around each basin for a 1 m
width.

F.32.10 STRIPPING
Where it is necessary to strip material in order to install a
municipal drain, the Contractor shall undertake such stripping in a
manner such that when restored, the topsoil returns uncontaminated
to the top of the stripped area. This would normally mean that the
topsoil would be stripped and piled separately from the subsoil.
The Contractor shall have regard for the working space provided for
such stripping operations. Unless approved otherwise by the
Engineer prior to work being undertaken, stripping shall be done
using an hydraulic excavator,
