MEMO TO: Mayor Vandernail and the Board of Trustees
FROM: Allen Nordin, CWP, Public Works Director
DATE: April 19, 2017
SUBJECT: Staff Report PW: Contract for Annual Wastewater Collection System
Maintenance; Cleaning and Video Inspection
MATTER BEFORE BOARD:
2017 annual contract for wastewater collection system maintenance and inspection program to
clean and video document the condition of approximately 31,000+ linear feet of sewer pipes
ranging in various sizes. This will address over one-third of the collection system infrastructure.
ACTION REQUESTED:
Authorization for the expenditure of budgeted funds from the Wastewater Fund and authorizing
the Town Manager to enter into a Public Services contract for outsourced services to clean and
video document approximately 31,000+ linear feet of wastewater collection system lines in a
not-to-exceed amount of $50,000.
EXECUTIVE SUMMARY:
The Town transitioned from a 7-year annual inspection to a three year annual sewer collection
system cleaning and inspection program in 2014. The collection system has been separated
into three zones to facilitate the new inspection rotation. This year’s work will be the start of the
second round of the three-year rotation.
BACKGROUND:
Following the dissolution of the Fraser Sanitation District in 2010, the operation and
maintenance of the wastewater collection system was placed under Public W orks. In 2011 the
Sewer Collection Maintenance & Inspection program was developed as a 7-year inspection
program allowing for one-seventh of the system to be jetter cleaned and video documented
each year while spreading out this expense over a multi-year period. Prior to 2014, staff had
already completed three years of maintenance and inspection activities from 2011 through
2013. The recommendation of CIRSA, Fraser’s property and casualty insurance carrier, is to
have our collection system inspected on a 3-year cycle. The Town Board adopted the
recommendation with 2014 being the start of the 3-year program.
Additionally, it provided baseline data of the North portion of the collection system and aided
staff with identifying areas with inflow & infiltration (I&I) that was in need of being rehabilitated
and/or replaced.

Since the Town does not own line cleaning and video equipment, it is necessary to outsource
this work. Fraser’s staff maintains a positive working relationship with a front range contractor
for this work.
Staff has researched alternate surrounding communities (Summit, Eagle and Denver counties)
for contractor options only to find that our current contractor is providing the Town with the most
cost effective service, given our limited window of opportunity for tracking I&I.
In addition to the maintenance and inspection components of our infrastructure, this program
assist the Town with identifying areas of I&I. The video information is beneficial in identifying
degrees of magnitude of infiltration entering the town main lines versus private service line taps
into the main lines.
As we move forward addressing I&I issues, staff continues working with our neighboring W ater
and Sanitation Districts by placing flow meters throughout our collection systems monitoring I&I.
There could be consequences associated to the lack of maintenance and rehabilitation of our
collection systems, one being potential legal claims from property owners suggesting the Town
may have been negligent in maintaining its infrastructure thus causing backups of wastewater
into owner’s properties, and another significant consequence could trigger the premature need
for a costly expansion of the wastewater treatment plant to allow for treatment of clean, cold
water from I&I.
ALTERNATIVES:
1. Do nothing, not recommended;
2. Approve as recommended.
RECOMMENDATION: This item has been placed under consent agenda.
Staff recommends approving Resolution No. 2017-04-05 authorizing the Town Manager to
enter into a Public Services Contract for sanitary sewer collection line cleaning and video
documentation services.
