| Objectives | The Dischargers WWTF serves the communities of Cutler, Orosi, East Orosi, Yettem, Seville, and Sultana. The WWTF is in Cutler at 40401 Road 120 in Tulare County. The WWTF and its discharges lie in the Alta Hydrologic Area of the South Valley Floor Hydrologic Unit (HU) as shown in the interagency hydrologic maps prepared by the CA Dept. of Water Resources (DWR) in August 1986. Waste Discharge Requirements Order No. 97-106, an NPDES permit adopted on 20 June 1997, regulates the discharge of 2.0 mgd of effluent from the WWTF to land via Discharge 001 and into Sand Creek via Discharge 002. Order No. 97-106 prohibits discharge or overflow of untreated or partially treated waste and imposes effluent limits for Discharge 001 and Discharge 002. The WWTF includes headworks, pump screws, two primary clarifier-digesters, two trickling filters, an oxidation ditch, a secondary clarifier, ultraviolet light (UV) disinfection, two unlined sludge lagoons, and 16 unlined sludge drying beds. Treated wastewater is stored in one of two unlined holding ponds prior to discharge or discharged directly without storage. The unlined holding ponds have a total pond bottom of 16 acres. Effluent evaporates and percolates from the holding ponds. Discharge 001 is recycling of wastewater on 106 acres of Discharger owned land. The Discharger has an additional 20 acres available for irrigation, pending the installation of irrigatin piping. The Discharger grows fodder, fiber, and seed crops on the land, primarily sudan grass in the summer and winter wheat or occassionally natural cloves in the winter. Both sudan grass and winter wheat ae moderately salt tolerant. Discharge 002 is to Sand Creek, a water of the United States, which runs parallel to the WWTF on its south and east sides. Discharge 002 occurs from the WWTF at Longitude 119 degree, 18 min, and 12 sec West, Latitude 36 degree, 31 min, and 23 sec North. Order No. 97-106 permits discharge to Sand Creek from November 1 through April 30 of each year. |
