Page 32 of 57 Specifications 5.19 - Operations and Maintenance WDR REQUIREMENTS Specification. 5.19 (pg. 27) “To prevent discharges to the environment, the Enrollee shall maintain in good working order, and operate as designed, any facility or treatment and control system designed to contain sewage and convey it to a treatment plant.” COMPLIANCE As described in Section 4.2, ICOM3 is used to generate work orders for routine sewer cleaning, CCTV inspection (condition assessment and construction inspection), FOG activities, repairs, refurbishments, replacements, manhole/structure inspections, service calls, and spill reporting. Sewer Cleaning Cleaning sewers is the City’s primary sewer maintenance activity. The City has both frequent, focused cleaning as well as cyclic cleaning for pipes not on the focused cleaning schedule. The City is currently on a one-year schedule to inspect and clean each public main pipe. Excessive grease buildup in City mains is also addressed through the FOG program areas. Problem areas are identified by Collections staff and forwarded to the City’s Engineering staff where they are prioritized and scheduled into the capital improvement program. Hot Spots Areas that have known problems such as excessive grease buildup or odor problems are cleaned and checked on a much more frequent basis based on experience history. Approximately 5% of the system is included in the Hot Spot cleaning program, with inspection on a weekly or bi-weekly basis, and cleaning on a 30, 60, or 90-day schedule. Cleaning frequency depends on the history and cause of stoppages or overflows on a line. Focused cleaning is performed primarily by jetting. A listing of the Hot Spots is found as Appendix 4.2. Root Control The City has both a focused and cyclic root treatment program. Roots encroach upon the interior of sewer mains through structural cracks, faulty pipe joints and defective laterals. Root intrusion is also a common problem in sewer laterals which are shallow. If roots are observed to be an issue during routine cleaning, in response to complaints, or through observations from CCTV inspections, root cutting is performed with chain flail attachments on the jetters or with mechanical cutters. The City also engages a contractor to perform chemical root control in the most affected pipes annually. CCTV Inspections The City maintains a television inspection program. Sewer segments undergo detailed video inspection for both structural and condition damage. The program’s goal is to televise the entire collection system every seven years. This goal has not been met recently, in part because the CCTV truck was frequently inoperable due to maintenance issues and the City lacked staff. However, a new truck has been budgeted, staff have been hired, and the City intends to expand its CCTV program. In addition, the City plans to hire a contractor to CCTV the larger pipes. The City will strive to meet its goal of CCTV’ing the entire system every seven years.
