City of San Leandro Sewer System Management Plan Volume I Following the education and outreach program, ES staff visit each FSE and conduct an inspection with an emphasis on FOG control, grease interceptor maintenance, and storm water Best Management Practices (BMPs). During these site visits, the City's FOG fact sheet is distributed and each of the elements (FOG, storm water, and integrated pest management) is discussed. Posters and storm water BMP guidance from the Alameda Countywide Clean Water Program are also distributed. Identification and Sewer Cleaning All lines within the collection system are inspected and cleaned annually. Priority is given to areas with a history of problems relating to FOG, roots or structural impairment. Areas with a history of FOG hot spots are investigated and cleaned quarterly. The areas requiring quarterly monitoring and cleaning frequency are downtown San Leandro and the service area surrounding the Bermuda lift station. FOG hot spots (areas with increased incidence of grease build-up) are cleaned to remove the risk of a blockage occurring and are subsequently inspected once per week. The sewer line is cleaned using either a hydro jet with spinning nozzle or a power rodder. The combo unit/vacuum truck is also used whenever feasible to recover the FOG. Additionally, information on the location, severity and possible source is relayed to the Environmental Services Section. Inspectors follow up at FSEs that may have contributed to the grease build-up. The collection crew continues to monitor the area weekly until the problem is abated through inspection or repair. Documents included in Appendix C: Food Service Establishment FOG Fact Sheet Food Service Establishment Wastewater and Stormwater Inspection Survey Food Facility Inspection Form Grease Interceptor Guidance Sheet Approximately 3.6 miles of the gravity sewer system are on the six-month priority maintenance schedule for flushing or both flushing and rodding, with some of these lines identified as grease problems. While the City has known areas with commercial grease sources (e.g. restaurants), most of the City's grease problems are in residential areas and the result of lines with poor grade. As part of the City's rehabilitation plan, the City is planning additional CCTV work throughout the system. The CCTV work is expected to help identify and verify causes of grease problems. Lines with known poor grade will be prioritized for CCTV inspection. With information on the causes of grease problems, maintenance activities and schedules can be modified or sewer repairs made to better control grease buildup and minimize grease -related SSOs.
