COUNCIL COMMUNICATION
AGENDA TITLE: Adopt Resolution Authorizing City Manager to Execute Purchase Order with
Aqua Aerobics, Inc., of Loves Park, Illinois, for Purchase of ReplacementAqua Disk
Filter Media and Frames ($33,465)
MEETING DATE: January 19,2011
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt resolution authorizing City Manager to execute purchase
order with Aqua Aerobics, Inc., of Loves Park, Illinois, for purchase
of replacement Aqua Diskfilter media and frames in the amount of
$33,465.
BACKGROUND INFORMATION: The Water/Wastewater Division utilizes Aqua Aerobic filters to treat
the secondary effluent at White Slough Water Pollution Control
Facilityto tertiary levels. The tertiary -treated effluent is disinfected
and applied to City land during the irrigation season or discharged
to the Delta during the non -irrigation season.
In 2000, the State required the City to begin treating its wastewater to tertiary levels. The filtration
system was commissioned in 2005 and over the past five years has experienced periodic fouling of the
filter media. Buildup of filtered material is normal and addressed during system backwash cycles. The
fouling results in excessive backwashing cycles to clean the filter media, however, causing increased
maintenance, higher energy costs and reprocessing of backwash flow.
The fouling is caused by a biological growth on the cloth media. Staff has tried several remedies
suggested by Aqua Aerobics and has found the most effective solution is to remove the filters and
manually clean them at periodic intervals. Purchasing replacement media will reduce equipment
downtime, make more effective use of staff time and improve process efficiency.
Aqua Aerobics is the sole source for this type of equipment. Staff recommends Council authorize the
City Managerto execute a purchase order with Aqua Aerobics, Inc., for the purchase of replacement filter
media and frames in the amount of $33,465.
FISCAL IMPACT: The replacement filter media enhances operational efficiency and reliability.
