Resolution approving the plans and specifications for the Southwest and 6th Avenue Pump Stations Control Panel Replacement and Generator Set Infrastructure project.  Project # PW21-14B

The 6th Avenue sanitary sewer pump station and the Southwest sanitary sewer pump station are two of the largest stations within the City’s sanitary sewer collection system and are critical to providing sewer service for the community.

Both stations are equipped with outdated equipment installed back in the early 1990’s and require a new generation of replacement equipment to function correctly with a new Supervisory-Control and Data-Acquisition (SCADA) platform. The current internal hardware is relay based and is being discontinued or no longer manufactured.  The project will replace the supervisory and process control panels which will give the Station Mechanics real time control of the pumps, trash rack, flow meters and backup generator set. This will also allow the station to be integrated into the new SCADA platform.

At the Southwest station, the backup generator set has the capability to power the station but it is not physically connected to perform that function automatically. This project will result in automatic power restoration when the service is interrupted. This back-up power feed will include powering all controls, pumps and building equipment until the main power is restored to the station. This project will also eliminate one pump powered diesel engine that is currently in place for main power interruptions.

The project will improve reliability and allow both stations to operate more efficiently.

A pump station rehab project was included in the FY21 CIP with a budget of $500,000 in sales tax funds.  Any additional funding necessary to complete the project will be paid from the Sanitary Sewer Operations budget.

Approval of this resolution. This project will remove and replace aged controls and systems for more efficient and reliable pump station operations.
