The 1992 improvements,which expanded White Slough to 8.5 <br /> I l w million gallons per Clay,is the largest public works project in the <br /> i . <br /> yl City's history. In recognition of the plant's standing in the <br /> environmental community,it was presented the"Plant of the <br /> qtr <br /> y sm. <br /> � g � Year"award by the Northern San Joaquin Section of the California <br /> Water Pollution Control Association. <br /> r The plant design features parallel treatment systems for domestic <br /> 1 2 3 <br /> and industrial wastewater. The domestic portion of the flow is <br /> _ treated in an activated sludge system.stem. The industrial wastewater <br /> is treated in aerated ponds. Effluent from both systems is <br /> reclaimed by irrigation on adjacent City-owned agricultural land. <br /> Y <br /> Storage ponds for winter industrial flows are included for use <br /> when conditions are too wet for land disposal. Domestic effluent <br /> ►� is discharged to the Delta <br /> at when irrigation needs have <br /> been met and during non-irrigation seasons. <br /> 5 6 <br /> r' ............. � <br /> 9 <br /> _v.
