| Details: | SUMMARY: Contact Tracer Study DETAILS: The City of Waldport owns and operates a Surface Water system, which supplies approximately 3000 people through 1100 connections. The City treats water from Weist and Eckman Creeks though a packaged flocculation/settling/multi-media filtration treatment system. In 2013, the Circuit Rider performed a tracer test on the WTP clearwell only. This was in anticipation of a capital improvement project. A formal report was not composed. Circuit Rider was contacted by Laura Burns (DWS) regarding the need for a determination on the available contact time in the City of Waldport system. Previous contact time determinations were complicated by various factors including flow determinations and the extended length of system detention. Visited water system to collect water treatment plant production and reservoir level data. Inspected the flow control system between reservoirs. Discussed operations with staff. Performed analysis of maximum potential flow through the contact reservoir. ACTION NEEDED: Complete analysis of available contact time. | ||
