DISCUSSION
Background
The City’s wastewater collection system is comprised of 135 miles of sewer lines. Some of the
pipes that make up the City’s wastewater collection system are over a century old and are in need
of spot repairs to ensure proper function and to extend their useful life. Scheduled repairs to the
collection system will allow the City to maintain the existing system in a preventative mode
rather than an emergency mode.
Project
This project will complete 24 sewer main line spot repairs throughout the City. Polyvinyl
chloride (PVC) pipe in conjunction with couplings will be used to replace damaged sections of
sewer line.
Other work included with this project includes the raising of five buried sewer cleanouts so they
can be accessed for maintenance work. The cleanouts were installed years ago but were never
raised to the roadway surface. Access to main lines through cleanouts or manholes is critical to
perform maintenance to prevent blockages and overflows.
Coordination with affected property owners has been done to minimize the impact during
construction. Hours and work days have been adjusted in repairs adjacent to schools streets to
eliminate traffic congestions during drop-off and pick-up hours.
For certain projects only a set of special provisions with no plans is generated, such is the case
for this project that because of the nature of the work, Staff determined that it was best to
advertise with a set of special provisions only. The special provisions have the necessary
information to complete all items of work per City Standards.
