Wastewater Treatment Plant (WWTP) Influent Wetwell Rehabilitation Project
Using Innovation to Repair Our Aging Infrastructure
WWTP Influent Wetwell Construction Begins June through November 2026
Updates will be posted here as needed.
Project Overview
The WWTP Influent Wetwell is a critical component of the City’s wastewater treatment system and has experienced significant deterioration due to long-term exposure to corrosive wastewater gases and aging infrastructure. To ensure continued reliability and regulatory compliance, the City has secured funding to rehabilitate and upgrade the facility.
The WWTP Influent Wetwell Rehabilitation Project is a $1.5 million project scheduled to begin this month with approximately 180 working days of construction. The project will address decades-old structural and mechanical deficiencies within the wetwell and associated pumping facilities, improving operational reliability and extending the service life of the influent wetwell as a component of the wastewater treatment system.
The project will include rehabilitation of the existing influent wetwell structure, replacement of deteriorated mechanical and electrical components, installation of corrosion-resistant materials, and upgrades to pumping and control systems. Construction methods have been selected to minimize service interruptions while maintaining safe and efficient wastewater conveyance throughout the duration of the project. These improvements will enhance system performance, reduce maintenance requirements, and provide long-term benefits to the community.

Project Schedule & Construction Notices
Safety along community arterials near the Wastewater Treatment Plant and surrounding facilities is of the utmost importance.
- Work hours will generally be between 7:00 AM and 6:00 PM, Monday through Friday. Occasional weekend or extended-hour work may be required to maintain the project schedule and minimize impacts to wastewater operations.
- Construction equipment, materials, and contractor staging areas will be located within designated areas of the Wastewater Treatment Plant site and directly across from the WWTP. All active work zones will be secured and clearly marked to protect public safety.
