Assistance Type: OTHER WATER QUALITY - Chlorine Supply Shortage
Reasons: Chlorine
 
Details: 6/23/21: Recovery of stored water was paused from the 108th ASR Well (SRC-BA) on 6/18 as a precautionary conservation measure in response to the possible chlorine supply shortage. The plan is to re-start recovery by the 3rd week in July. They are closely monitoring residual levels more frequently and lowered residual set point in half to 0.50mg/L at the A2 reservoir to preserve chlorine stock. As of 6/16 we had about 230 gallons left.

6/24/21: Priority is the chem-trailer which feeds A2 reservoir to help maintain a chlorine residual. System estimates they have a 306 day chlorine supply under current trailer operation and 153 days under normal residual set point.

6/25/21: System restarted the ASR well the afternoon of 6/24 in preparation for a forecasted increase in demand and received 55 gallon drum of chlorine on 6/25.
