Good afternoon Prairie Grove: It’s officially summer. It’s hot and it’s dry, and lots of folks are spending time outside using water. Unfortunately, just like last summer, that means we’re exceeding the capacity of the system to supply water. Over the past week, the storage tanks at the Sherwood Forest well have been starting each day about a half foot lower than the day before – and the problem is accelerating. As we’ve said before, even without this increased usage, the well is unable to supply enough water for needs during the day, but it is generally able to recover overnight when usage is low. Unfortunately, as daily demand increases, it has outstripped the ability of the well to fully replenish the tank levels overnight. Unless we all begin immediately practicing the protocol in the Stage 5 Drought Contingency Plan that was implemented in the Summer of 2022 (which has remained active), then we will almost certainly have a system shutdown before the weekend is over. We’ve provided a graph of the Ground Storage Tank levels over the past two weeks (blue line). Based on this pattern and expected demand, we’ve projected (orange line) that levels will likely bottom out very quickly over the weekend. Once the system drops below eight feet (red line), we’ve reached the critical point and we must shut down the system to allow it to fully recover. We have partially closed the outgoing valves from the plant to approximately 15% of normal levels to attempt to slow the demand, but that will not be enough. It will take your help as well. Some things we MUST all begin doing immediately to prevent the system going into emergency operations mode, which will include temporary shutdowns of the system as we have seen over the past few […]
