Scotts Avenue <br /> Stockton, CA 95205 <br /> INSPECTION REPORT, COUNTY SER VICE AREA 15(WATERLOO), SAN JOAQ UIN COUNTY <br /> Enclosed is a report summarizing my inspection, performed on 20 June 2000, of the County Service <br /> Area No. 15 (Waterloo) wastewater treatment plant. In general, the wastewater treatment plant was <br /> clean and well maintained. A site inspection photograph log is enclosed with this letter. <br /> The following observations were made during the site inspection: <br /> • All wastewater is being discharged to the return activated sludge package plant. Effluent from the <br /> activated sludge plant is discharged to three polishing ponds located in series prior to discharge to <br /> one of four evaporation/percolation ponds. <br /> • Limited odor was noted while on the catwalk above the return activated sludge plant and at the <br /> polishing ponds. There was no objectionable odors noted at the evaporation/percolation ponds. <br /> • The freeboard in the ponds was acceptable. <br /> • Wasted sludge from the return activated sludge treatment process is discharged to the southwest <br /> evaporation/percolation pond. <br /> • The wastewater screen is manually raked every day. Screenings are transported to a landfill for <br /> disposal. <br /> If you have any questions on this information, please telephone me at (916) 255-3116. <br /> 1_1 <br /> TIMOTHY R.
