AWWA MTC61108

The City of Clovis, California constructed a state-of-the-art membrane water treatmentfacility to meet ever growing demands in the area. The plant has an initial ratedcapacity of 15 mgd facility (buildout at 45 mgd) and treats water from an irrigation canaloperated by the Fresno Irrigation District. The City of Clovis has experienced rapidpopulation growth in the last ten years. This growth put a strain on the existing watersupply system, which came almost exclusively from groundwater. Despite itsgroundwater recharge program, increased demand of the available groundwaterresources resulted in the continued drop in the water table to the point where growthwas not sustainable. The plant uses membrane filtration, and also has pretreatmentaimed at reducing color and organics. The City selected ballasted flocculation, whichuses a polymer as part of its operations. Residuals handling facilities utilize aproprietary process that relies on sludge conditioning using a polymer and in-linehydraulic mixing-flocculating unit. This poster displays water quality and cost data usedin developing the design of these facilities, and water quality and plant operating datathrough the first 6-9 months of operation of the treatment plant.
