AGENDA TITLE: Approve Specifications and Authorize Advertisement for Bids for Removal,
Dewatering, and Disposal of Approximately 500 Tons of Biosolids from
White Slough Water Pollution Control Facility Storage Lagoons
MEETING DATE: November 17,2010
PREPARED BY: PublicWorks Director
RECOMMENDEDACTION: Approve specifications and authorize advertisement for bids for
removal, dewatering, and disposal of approximately 500 tons of
biosolids from White Slough Water Pollution Control Facility storage
lagoons.
BACKGROUND INFORMATION: The biosolids storage lagoons at the White Slough Water Pollution
Control Facility(WSWPCF) are utilized for storage and
concentration of solids from the four anaerobic digesters. During
the summer months, this material is applied to the land application
areas, but in the winter, the solids are stored in two concrete -lined lagoons. In order to prevent biosolids
from spilling over to the Facility's unlined storage ponds, it is necessary to dewater and dispose of the
excess solids at an offsite landfill until the new solids handling facility is completed.
This is the last time the City will be contractingfor dewatering services as the solids -handling facility is
scheduled to be operational prior to winter 2011. Thereafter, dewatering operations will be performed by
City staff at the new facility.
The specifications are on file in the PublicWorks Department. The planned bid opening date is
December 2,2010.
FISCAL IMPACT: The project estimate is $215,000.
FUNDING AVAILABLE: Wastewater Fund (170403)
Budgeted: Fiscal Year 2010/11
