Regional Infiltration and Inflow Control Program |
|||
|
Local Agency InvolvementKing County and local agencies are working together to develop the Regional I/I Control Program. They cooperatively developed the criteria for selecting pilot projects, and draft standards and policies for I/I control. They are also working together to decide how the regional program should be carried out and funded beyond 2005.
Local sewer agencies in the King County service areaThe King County wastewater interceptors, pump stations, treatment plants and outfalls serve 34 tributary, but politically and administratively independent, local sewer agencies.
Increased wastewater flows within the County have taken up significant portions of, and in some cases exceeded, the existing facilities' carrying capacity. Further, it has been determined that infiltration and inflow (I/I) claim a significant portion of facility capacity during wet weather conditions. To protect the environment and accommodate the needs of local agencies, a balance of expansion of County facilities and rehabilitation of both County and tributary local agency collection facilities must be achieved. In addition, a structure for financing the costs of the necessary capital improvements in a manner acceptable to all participants must be devised. Local agency workshopsThe implementation of the County's Regional I/I Control Program includes the continuous need to build and maintain consensus with the local agencies throughout the contract term. Key to the consensus building process throughout the Regional I/I Control Program is the work of the local agency and policy managers to maintain clear lines of communication between the local agencies and King County throughout the Program. This approach has proven to be instrumental in the successful implementation of key elements of the Regional I/I Control Program. Regional Water Quality Committee (RWQC)The Regional Water Quality Committee develops, reviews, and recommends countywide policies and plans for water quality and sewer service issues, long range capital facilities plans, rate policies and facilities siting to guide King County’s regional water quality responsibilities for consideration by the Metropolitan King County Council. |
