The City of Clovis, California constructed a state-of-the-art membrane water treatment
facility to meet ever growing demands in the area. The plant has an initial rated
capacity of 15 mgd facility (buildout at 45 mgd) and treats water from an irrigation canal
operated by the Fresno Irrigation District. The City of Clovis has experienced rapid
population growth in the last ten years. This growth put a strain on the existing water
supply system, which came almost exclusively from groundwater. Despite its
groundwater recharge program, increased demand of the available groundwater
resources resulted in the continued drop in the water table to the point where growth
was not sustainable. The plant uses membrane filtration, and also has pretreatment
aimed at reducing color and organics. The City selected ballasted flocculation, which
uses a polymer as part of its operations. Residuals handling facilities utilize a
proprietary process that relies on sludge conditioning using a polymer and in-line
hydraulic mixing-flocculating unit. This poster displays water quality and cost data used
in developing the design of these facilities, and water quality and plant operating data
through the first 6-9 months of operation of the treatment plant.
