Interceptor Rehabilitation 2020 - 2022

1. Rehabilitating approximately 2,200 linear feet of existing North Primary Influent and Effluent Conduits to and from North Primary Clarifiers ranging from 42 to 114-inch diameter, 3 diversion chambers and the 6-foot by 6-foot North Primary Effluent Collection Channel. 2. Rehabilitating approximately 35,000 linear feet of existing interceptor pipe segments. Through the Interceptor Condition Assessment Program, initial pipe segment condition ratings are determined by the RR&R Department Transmission Division CCTV inspection and final condition ratings by Engineering Department review of the CCTV inspection. Pipe segments rated Very Poor are rehabilitated. Pipe segments rated Poor or Fair/Poor that are immediately adjacent to the Very Poor segments are also considered for rehabilitation. The goal is to rehabilitate longer contiguous runs of pipe segments that include Very Poor and Poor segments, and Fair/Poor segments as appropriate, resulting in lower overall costs for rehabilitation and reduced overall impact on the public. 3. Rehabilitating approximately 45 existing manholes based on the RR&R Department Transmission Division Surface Inspection and Engineering Department review and inspection.
