CITY COUNCIL AGENDA REPORT
MEETING DATE: AUGUST 8TH, 2016
AGENDA #: 5B
PREPARED BY: KATY GEHLER, PUBLIC WORKS DIRECTOR
PRESENTED BY: KATY GEHLER
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION AUTHORIZING THE
EXECUTION OF THE CITY’S STANDARDIZED CONTRACT FOR THE
2016 SANITARY SEWER TELEVISING
DISCUSSION: Introduction
The purpose of this agenda item is to authorize the Mayor and City
Manager to execute the City’s Standardized Contract with Pipe Services to
complete Sanitary Sewer Televising as identified in the 2016 Sanitary
Sewer Enterprise Fund budget.
History
Sewer backup claims comprise a significant portion of liability costs for the
League of Minnesota Cities Insurance Trust (LMCIT). Sewer backups not
only cost a lot of money but sewage in basements cause significant
inconvenience to property owners. LMCIT provides guidance on how to
limit the risk of these claims including having good policies regarding
operation and maintenance of sewer lines which include completing regular
inspections to inform the City of these potential risks. Policies for
maintenance activities help plan for use of the City’s resources, establish
priorities for this type of work, and provide an explanation as to how the
City performed the maintenance. Televising sewers is a key component.
The main objective for sanitary sewer televising is to obtain visual
documentation of the sewer main, sewer manholes and
residential/commercial lateral connections overall condition. This
documentation can be used to plan regular maintenance along with
informing staff when larger replacement or rehabilitation projects are
needed. Televising records also help with litigation issues that may arise
and is recommended by LMCIT.
Sewer televising is accomplished by taking video of the sewer main from
manhole to manhole with a specialized corded video camera. Information
gathered is then put onto a storage device for City staff to review. During
the review, staff is able to see root intrusions, protruding services, I & I
(infiltration and Inflow), broken and collapsed sewer main, corrosion, blocks
and sediment. Staff can then address issues that need immediate attention
and schedule others for a later date.
Current Circumstances
2
Sewer televising has historically been accomplished with a combination of
in-house work and contracted services. The sanitary sewer budget
includes an allotment for the outside services.
The City has designated approximately 100,000 lineal feet or about 19
miles of our 117 mile sanitary sewer system for contract televising in 2016.
This does not include televising that goes along with all street
reconstruction projects and other work completed in house.
For the 2016 services staff prepared a specification and obtained quotes
from 2 vendors. The quotes were based on a per linear foot charge with
the final amount paid to be calculated on the actual work completed. A
summary of the quotes is below:
Company
Linear Foot
Cost
Pipe Services $0.39
Hydro-Vac $0.45
Conclusion
Staff is recommending awarding the contract to the lowest bidder, Pipe
Services in the amount of $0.39 per linear foot. Pipe Services has
previously worked for the City of Prior Lake and has completed televising
services successfully.
ISSUES: Completing televising on a regular basis provides the city with more
comprehensive, up to date information on its municipal sanitary sewer
system. It is very difficult to effectively operate and maintain a sanitary
sewer system with limited or dated information. Televising provides the
needed information to best make management decisions regarding
operations, maintenance and replacements ensuring funds collected from
the sanitary sewer fees are being spent most effectively.
Cities also need to exercise reasonable care for sewer systems to avoid
sewer back-up liability. This means cities must establish an inspection and
maintenance program and emergency procedures. Completing this work
will ensure the city is meeting the “standard of reasonable care”.
FINANCIAL
IMPACT:
The 2016 Sanitary budget allows for $55,000 for Maintenance Agreements
for sewer televising and collection system related work. This project will
allow up to $45,000 in expenses, leaving $10,000 for miscellaneous
projects and emergency work through the end of the year.
ALTERNATIVES: 1. Motion and a second as part of the consent agenda to approve the
resolution which authorizes the Mayor and City Manager to execute the
City’s Standardized Construction Contract with Pipe Services for 2016
Sanitary Televising.
2. Remove this item from the consent agenda for additional discussion.
