Water Report — April 2026

Water Report, April 2024

In April, I toured the village water plant with Jake. I took note of the well placement in and around the solar field, the interior of the main room where water is pumped from the wells into the village system, and the room where the main computer resides for remote and onsite monitoring. Jake pointed out a well that was no longer in use due to water quality. I gained a better understanding of how a more stable internet connection can provide more efficient remote monitoring. We are waiting on Archtop to install fiber to the site for a more secure connection.

Details

• Average Daily Volume of Treat Water: 226,898 gallons

• Total Volume of Treated Water: 6,806,953 gallons

• Average Chlorine Residual at Entry Point: 2.02 mg/l

• Testing revealed E. coli and coliform bacteria were absent at all testing sites.

Additional notes:

• Completed repairs at pump #12 include a new pump and drop line.

• The check valve in the water treatment plant has been approved by DOH and is scheduled to be installed the week of 5/11

• The replacement of the pump & motor for Well 13 is waiting for pump size clarification from Delaware Engineering
