2022 Sewer Rehabilitation Project

The District is responsible for operating and maintaining 15.6 miles of gravity sewer mains, most of which were constructed in the late 1970s. Many of these assets are beginning to reach the end of their 50-year design life. In recent years, portions of the sewer collection system have required significant emergency repairs, and an inspection of the entire system has revealed that sections are at risk of potential failure. Additionally, the District has noticed increasing levels of inflow and infiltration (I/I) of surface water into the sewer collection system.

The District is preparing to start construction on the 2022 Sewer Rehabilitation to repair or replace approximately 21,000 feet of aging sewer pipelines throughout the District. Repairing the sewer collection system will reduce I/I and improve the long-term condition of the sewer collection system.

The project is estimated to cost about $5.1 million. The District is pursuing low-interest financing for this project to smooth costs over time and minimize the bimonthly bill impact on ratepayers. The capital surcharge will fund debt service payments on the project financing rather than funding the entire project cost upfront in one year.
