Sewer System Rehabilitation Program
The Federal Environmental Protection Agency and the state Environmental
Protection Division have approved the City’s plan to eliminate
sanitary sewer overflows (SSO’s). This plan includes a comprehensive
sanitary sewer evaluation survey (SSES) using state
of the art evaluation methods. The SSES for Sewer Group 1 involved an
unprecedented level of investigation, which included the Closed-Circuit
TV analysis of 326 miles of sewer pipe, cleaning 159 miles of pipe (removing
437 tons of sewer debris), and inspection of 8,045 manholes. Following
the survey and evaluation period, the field information was analyzed
to identify specific locations in the sewer system where construction,
rehabilitation, and repair work are needed. After extensive investigation
and documentation of defects is completed, a rehabilitation plan was
developed, identifying necessary sewer repairs and replacement. This
program also employs a “Find
and Fix” approach for evaluation and repair of sewers in areas
that have limited capacity.
What is the Project Status?
Work in Sewer Groups 2 & 3 is currently underway to rehabilitate lines identified under the SSES program as in need of repair. If you live in the affected area, you can expect to see field crews replacing sewer lines that run under city street and roads and on private property, within the City’s easement. You can also expect written notifications, door hangers, and automated phone messages alerting you when construction will take place on your street. Partial street closures may be necessary from time to time.
Every effort will be made to reduce the impacts of this program on residents and business owners. Thank you for your patience as we work to improve the sewer system in your neighborhood.
In a sanitary sewer system, there are several factors, which contribute to an overflow event: age, capacity, grease, debris, infiltration, etc. The rehabilitation and repair work is designed to eliminate SSOs (sewer overflows) and increase sewer capacity, which will be accomplished using the least disruptive techniques possible, such as trenchless technology (i.e., cured-in-place pipe or pipe-bursting techniques).
