Details: SUMMARY: Received request from Wickup WD for assistance with equipment recommendations for pH control for WTP A DETAILS: The system owns and operates two water treatment plants to treat surface water which supply water to approximately 620 connections with a population of approximately 1702 people. WTP A is a slow sand filter plant rated for 100 gpm. WTP B is a package treatment plant with coagulation, flocculation, sedimentation, and rapid sand filtration rated for 150 gpm. The plant was designed for 175 gpm however the maximum output is 150 gpm due to the poor water quality produced at 175 gpm. Both Plants have post hypo chlorination. Received assistance request from Daryl Gardner, operator for the Wickiup Water district. The district had recently failed a lead and copper test. The district requested assistance with equipment recommendations at WTP A for pH adjustment for corrosion control. Received last round of testing for lead and copper tests from District. Continued research on the need for corrosion control due the failed lead and copper test and the proper chemical addition and equipment that may be needed at WTP A. Have begun recommendations report for the district. ACTION NEEDED: Complete and submit report with recommendations to district.
