The System Integration Charge is the rate charged specifically to cover the capital costs of constructing improvements to connect the collection system in the City of Ridgefield with the District’s system. These improvements ultimately allow for flows to be treated at the Salmon Creek Treatment Plant, which is a much larger and more cost-effective facility. This charge will decrease as growth occurs in Ridgefield and new connections are made to the sewer system, all in accordance with the terms of the “City of Ridgefield and Clark Regional Wastewater District Collection System Transfer and Operating Agreement”.
