AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for Solids
Handling Facility Improvements at White Slough Water Pollution Control Facility
MEETING DATE: October 19, 2022
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for bids
for Solids Handling Facility Improvements at White Slough Water
Pollution Control Facility.
BACKGROUND INFORMATION: On April 15, 2020, Council authorized the City Manager to execute a
Professional Services Agreement with Carollo Engineers, Inc. to
provide assistance with the procurement and installation of a new
sludge dewatering press, and digester mixing system improvements at the White Slough Water Pollution
Control Facility (WSWPCF).
In certain conditions, the performance of the existing sludge dewatering equipment at WSWPCF cannot
remove the amount of moisture needed to properly handle the material. Based on recommendations from
Carollo Engineers, Inc., the City has decided to install a new screw press to improve the sludge dewatering
process; and install a new sludge mixing system in Digester No. 3 needed to improve the sludge
stabilization process.
This project, if approved will facilitate the procurement and installation of one sludge dewatering press and
ancillary equipment; and a sludge mixing system to be installed in Digester No. 3.
The specifications are on file in the Public Works Department. The planned bid opening date is
December 7, 2022. The project estimate is $2,500,000.
FISCAL IMPACT: This project is necessary to maintain wastewater treatment compliance and
to avoid potential fines and penalties from the State. This does not impact
the General Fund.
FUNDING AVAILABLE: Funding will be identified at project award-
