Assistance Type: SURVEY/DEFICIENCY FOLLOW-UP
Survey: 11/23/2021
Reasons: Operations
 
Details: The system has been contacted multiple times ( 04.29.22, 05.09.22 and 05.31.22) to discuss the survey deficiencies that have not yet been resolved. Corinne has been advised to provide new due dates if more time is needed to correct the deficiencies.

Pending deficiencies and next steps:

1. No means to adequately determine flow rate on contact chamber: With the new tanks and plumbing configuration, tanks 1 and 2 will be used as contact chambers. A flow meter and sample spigot at the effluent side of tank 2 should be installed to keep track of flow and to measure pH, temperature, and chlorine for daily CT calculations. NEXT STEPS: Provide pictures confirming that a flow meter is installed at the effluent side of tank 2.

2. New tracer study required: NEXT STEPS: Corinne was instructed to coordinate with Civil West to determine when the tracer study will be completed. The due date can be extended, but the system has not provided a date when they plan to resolve this deficiency.

3. Four homes with subsurface drip irrigation systems connected to Weiss Estates water system. NEXT STEPS: Corinne will verify the status of these homes and confirm if the lines have been capped off, or if the homes have double check valves installed.

4. Two homes with domestic wells. NEXT STEPS: Include the home with backflow assembly test results in the 2021 ASR and verify that the other home with a domestic well is capped off, with no electrical conduit or piping hooked up to the water system.

5. Cross connection at the WTP. NEXT STEPS: The system is required to install a reduced pressure backflow assembly upstream from the manual valve (MV 11) and prior to tanks 4 and 5. Make sure the backflow prevention assembly installed does not stop the membrane filter from operating correctly. The backflow assembly must be tested annually and listed in the yearly ASR.

6. Hose connected to the entry point sample tap. NEXT STEPS: Install a HBVB at the EP sample tap.
