Contract One Sewer Rehabilitation

Construction on the Contract One Sewer Rehabilitation Project will begin Wednesday, March 18, focusing on the Suzanne Drive - Wallis Road area. Work hours are generally 7 am to 4 pm.

The contractor National Water Main Cleaning Company will be repairing a small section of sewer main on Wallis Road the week of March 16. The section of sewer main to be repaired is approximately 80-feet in length and will require excavation.

Background

The Sanitary Sewer System Rehabilitation and Improvements – Contract 1 project is required by the City’s Consent Decree with the United Stated Environmental Protection Agency. The purpose of the project is to remove Inflow and Infiltration (I/I) in the City’s sewer collection system. I/I is when stormwater and groundwater enter the sewer collection system through deterioration in the sewer pipes or manholes. This results in increased sewer flows, more frequent Combined Sewer Overflow (CSO) events, and increased sewer costs through pumping and treatment of otherwise clean water.

The City accepted funds through the American Rescue Act Plan (ARPA) to assist with costs related to design and construction. The ARPA funding deadline means the project must be completed by April 1, 2026.
