AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for
White Slough Water Pollution Control Facility Digester Painting Project
MEETING DATE: June 19, 2013
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for
bids for White Slough Water Pollution Control Facility Digester
Painting Project.
BACKGROUND INFORMATION: The White Slough Water Pollution Control Facility (WSWPCF) has
_.. four anaerobic digesters. Digester No. 4 was installed in 2007 and
the current paint coverage is adequate. Digester No. 3 was last
painted during its installation in 1991. Digesters Nos. 1 and 2 were installed in 1967 and believed to
have been painted in 1991 when No. 3 digester was painted. Photos are attached.
The inherent corrosive atmosphere at WSWPCF intensifies the paint oxidization (rusting) at the
digesters. The digester pipes, pipe connections and roof tops are severely corroded and will continue to
corrode without the proper paint protection. Eventually, the corrosion will create holes and voids in the
piping. The holes in the piping will render the piping useless and allow methane to escape into the
atmosphere, increasing the corrosive damage. Associated digester equipment, such as pumps and
compressors, is not included in this project.
Plans and specifications are on file in the Public Works Department. The planned bid opening date is
July 17, 2013. The project estimate is $90,000.
FISCAL IMPACT: If the digesters are not painted; the oxidation or rust will continue until it
eats into the piping, resulting in a digester failure and emergency painting
FUNDING AVAILABLE: Funding will be identified at project award.
