INFORMATIONAL MEMORANDUM
TO: Mayor Haggerton

SUBJECT: CBD Sanitary Sewer Rehabilitation
Project No. 91140203
Emergency Sewer Repair at 1227 Andover Park East
ISSUE
Update Utilities Committee on an emergency sewer repair at 1227 Andover Park East.
BACKGROUND
City staff was in the process of cleaning the sanitary sewer in Andover Park East in
preparation for the 2015/2016 CBD Sanitary Sewer Rehabilitation Project. The jet head
used for cleaning became obstructed and medium to large gravel debris was present within
the sewer system, indicating a possible break in the sewer main. The City contracted with
Bravo Environmental to video the sewer line. During the videoing their camera became
lodged in a hole in the bottom of the pipe and could not be removed. It was determined that
it was necessary to excavate the sewer main in order to remove the camera and determine
the extent of the damage to the sewer main as an emergency situation.
DISCUSSION
R.L. Alia (Alia) was hired to perform the necessary emergency excavation on a time and
materials basis. Bravo Environmental's camera was extracted and the repair of the pipe is
the next step. The extent of the pipe repair will be determined after the damaged section is
exposed for visual inspection.
FISCAL IMPACT
The repair work being completed by Alia is being performed under force account to track all
actual costs. This work will be paid for using 2015/2016 CBD Sanitary Sewer Rehabilitation
Project funds.
RECOMMENDATION
Information only at this time. An emergency declaration Resolution will be brought back to a
future Utilities Committee meeting.
