SUBJECT:
T12-055 – Lateral Sewer Pipe Bursting
RECOMMENDATION:
McGillivray & Sons
That Tender T12-055 – Lateral Sewer Pipe Bursting, be awarded to
Contractors Limited, St. Agatha, Ontario
at their tendered price of $134,319., including
provisional items and contingencies of $6,569., plus H.S.T. of $17,461.47, for a total of
$151,780.47.
BACKGROUND:
The City of Kitchener runs an annual program to improve the sanitary sewer service to local
properties. The list of properties is derived from the Operations Department, through the number
of complaints reporting sewer lateral backups at these properties. The sewer lateral is videoed
by Operations to determine the cause of the backup. Once determined that the backup is
caused by a City related issue, such as tree root intrusion, or deteriorated existing pipe, the
property will be included on a list for sewer lateral repairs. Engineering will determine which type
of sewer lateral rehabilitation should be completed based on the type of structural defect, the
location, and accessibility of the repair. If the lateral is a trenchless candidate, based on the
criteria, it will be included on the trenchless lateral repair list.
The Pipe Bursting trenchless method is used to complete these deficient laterals, as it is a very
cost effective and environmentally friendly method of rehabilitation. Typically, there is very little
excavation/digging required to complete this work. The work requires an access pit to be
opened at the main sewer line in the roadway and an access pit opened at the property line
where the existing sanitary lateral is located. If the problem extends past the property line, due
to City tree root intrusions, the sanitary sewer lateral will be replaced to either the house
foundation or to the inside sewer cleanout of the house, if accessible, at no additional charge.
A new continuous sewer service lateral pipe is pulled through the old sewer service, and a
permanent connection is made at each end. The intent is to restore the structural integrity by
installing one continuous pipe and eliminating further sewer backups caused by root intrusions
and structural defects.

The pipe that is recommended and used with the trenchless Pipe Bursting method is called High
Density Polyethylene Pipe (HDPE). This pipe is a proven cost effective pipe that is extremely
tough and durable for sewer lateral rehabilitation using the Pipe Bursting method. Once this pipe
has been installed, the sewer lateral has a new life expectancy of 50 plus years.
