INFORMATION SHEET <br /> CITY OF LODI <br /> WHITE SLOUGH WATER POLLUTION CONTROL PLANT <br /> SAN JOAQUIN COUNTY <br /> The City of Lodi White Slough Water Pollution Control Plant receives wastewater <br /> from separate sanitary and industrial sewers which serve about 40,000 people. <br /> Domestic waste is treated by the 5.8 mgd activated sludge plant; industrial <br /> wastewater is treated in a series of ponds designed to handle 2.3 mgd. <br /> The plant, according to self-monitoring reports, is reaching capacity. There- <br /> fore, the City has retained Black and Veatch to conduct a facilities and <br /> operations study for the plant's planned expansion. <br /> The Basin Plan mandates the Regional Board to encourage the disposal of waste- <br /> water on land where practicable. In conjunction with this, Table 5-2 (page <br /> I-5-15) of the Basin Plan shows that the City of Lodi should go to land disposal <br /> or irrigation from May - October. In order to meet these objectives, the <br /> requirements include the more stringent BOD and SS limits of 20 mg/l monthly <br /> average and 40 mg/l weekly average which the City has to meet if they discharge <br /> to Dredger Cut during the irrigation period. The City reclaims approximately 50 <br /> -60 percent of treated domestic and industrial wastewater for irrigation of beef <br /> cattle fodder on a fenced 650-acre parcel owned by the City. The 30 mg/l <br /> monthly average and 45 weekly average limits for BOD and SS are EPA secondary <br /> treatment effluent standards required of discharges to surface waters. <br /> The City discharges treated, chlorinated, and dechlorinated domestic wastewater <br /> to Dredger Cut at a point approximately 6,000 feet (1.1 mile) to the east of <br /> White Slough - Bishop Cut - Dredger Cut confluence. <br /> Soils of the area are generally alluvial clay loam and sandy loam. Depth to <br /> ground water is approximately twelve feet. <br /> The City also has an EPA approved pretreatment program which, in conjunction <br /> with City Ordinance #1307, regulates the industrial wastes that can be dis- <br /> charged into the City's industrial wastewater plant. The following industries <br /> contribute to the City's wastewater facility flow: <br /> 1. Cereal , breakfast foods <br /> 2. Plating, polishing, engraving, and plate printing <br /> 3. Canned fruits and vegetables <br /> 4. Meat packing <br /> 5. Laundry and garment <br />
