DEPARTMENT: Department of Public Works
SUBMITTED BY: Richard Dublinski, Director
BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Department of Public Works maintains the City’s system of storm sewers. Storm sewers have a functional lifespan of approximately 75 years. As a storm sewer ages, the pipe develops cracks caused by material degradation, soil settlement, root intrusion and/or adjacent construction. When a segment of storm sewer approaches the end of its useful life, the extent and severity of pipe degradation results in a high probability for pipe/system failure. Pipe failure may cause sinkholes in roadway surfaces and may also result in flooding of homes, businesses and/or public rights-of-way. The City has relined approximately 200,000 linear feet of pipe since the inception of the Storm Sewer Lining Program (SW017) in 2004, which has led to a reduction in localized flooding and related complaints.
In 2019, DPW established CIP SW037, Corrugated Metal Pipes (CMP) Repair and Replacement Program. This multi-year program will evaluate the condition and identify solutions to maintain the City’s CMP pipe within its stormwater infrastructure. There are twelve and a half miles of existing CMP at 778 different locations, averaging over 30 years of age and ranging from 10 to 60 inches in diameter.
DPW and the Water Utilities both have lining programs. The programs are bid separately because the location and size of the pipe is different enough to affect pricing. The majority of DPW’s storm water system is in the right-of-way, while the Water Utilities has substantially more pipe being lined in resident’s yards, making it more difficult to perform the work.
