Details: Country Club Estates operates a treatment facility serving 17 home sites approximately 5 miles south of the city of Coos Bay Oregon. Water supply comes from Coos Bay North Bend Water supply and is gravity fed through piping under the Isthmus Slough approximately 6,000 feet prior to being chlorinated and pumped into a series of tanks which supply the system’s users. The water receives chlorine disinfection and filtration which requires a .5 log inactivation CT.
The Country Club Estates system tracer study methodology, per the current configuration, was reviewed by OHA representatives, and decided that the current system configuration would not meet disinfection requirements for proportional flow. The system would require modification prior to running the tracer study. They are currently making fine adjustments to the system, post modifications, to achieve target chlorine residuals.

4-12-18 to 6-29-18 – Assist Country Club Estates with operations:
1. Regular emails with OHA related to system and updates with operations status.
2. Regular phone calls with Rex Miller as they modify their system and make recommendations on system parameters and answer general questions.
3. Site visits periodically to check residuals and provide feedback to operator.

Tracer study to be scheduled once dosing is stable, as system seems to be functioning properly otherwise.

The technical memo will be prepared and submitted 7/3/18
