BACKGROUND
The Environmental Utilities Department has an ongoing repair and maintenance program for its sewer collection system. To date, the rehabilitation program has
repaired over 17 miles of defective sewer pipeline.
Closed-circuit television (CCTV) was used to inspect 26 miles of the pipeline
interior and based on severity of defects, segments of pipeline were prioritized
for repair.
This year’s plan is to repair approximately 13,400 linear feet of the sewer
collection system that has cracked and/or deteriorated pipe. Additionally, the
rehabilitation will include repair of approximately 340 service laterals to provide a
seal between the repaired sewer pipe and the lateral connection. The defective
pipe and lateral connections will be repaired using ultraviolet (UV) light cured-in-place
lining technology where the existing pipe is lined without excavation and
therefore resulting in significant cost savings. Access to the pipe will be provided
at existing manholes. Eliminating the need for excavation also provides for minimal traffic and neighborhood or business disruption.
A copy of the plans and specifications are available at the City Clerk’s office for review.
