AGENDA TITLE: Adopt Resolution Authorizing Purchase of Ultraviolet (UV) Light Disinfection Lamps
for White Slough Water Pollution Control Facilityfrom Coombs-Hopkins/DC Frost,
of Walnut Creek ($175,000)
MEETING DATE: August 5, 2009
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing the purchase of ultraviolet (UV) light
disinfection lamps for the White Slough Water Pollution Control
Facility (WSWPCF) from Coombs-Hopkins/DC Frost, of
Walnut Creek, in the amount of $175,000.
BACKGROUND INFORMATION: UV lamps are the most important fixtures in the disinfection system
at WSWPCF. The City no longer uses chlorine compounds to treat
wastewater, thereby avoiding the risks associated with chlorine
handling and eliminating disinfection byproductsthat have been
determined to be harmful to the environment.
The disinfection system became operational in 2005. Since then, staff has reduced costs by replacing
the UV lamps only when they reach the manufacturer's recommended maximum 12,000-hourlamp life.
The new 2007 Waste Discharge Permit requires treatment to Title 22 requirements and the California
Department of Health Services has determined that to meet these requirements, the maximum lamp life
must be held to no more than 9,000 hours. To assure continual compliance with the Discharge Permit,
the City needs to install 1,100 new UV lamps in six of 10 banks of the disinfection system. The lamps
being replaced have reached or exceeded their useful life.
The lamps will be supplied by Coombs-Hopkins/DC Frost, the representative for Trojan Technologies, Inc.,
the sole supplier of replacement parts for the system. The lamps will be installed by City staff.
FISCAL IMPACT: The cost to replace the lamps is $175,000. Failureto install the lamps would
subject the City to State fines. The anticipated annual cost to maintain the
lamps within maximum operating hours is estimated at $150,000.
FUNDING AVAILABLE: White Slough Water Pollution Control Facility Operating fund (170403)
