The Prairie Grove Water Supply Corporation (WSC) is a rural water system, located approximately 0.5 miles east of the City of Diboll. Its service area extends east along FM 1818 for approximately 5 miles.

The WSC was created in 1965 to serve the Prairie Grove community, and over time, the community grew, as did the WSC. However, like many small, rural water systems, the WSC struggled to maintain its infrastructure and meet the increasing regulatory demands for water treatment. With no support staff or funding to repair the failing infrastructure, the WSC was unable to keep the system in compliance with state and federal regulations. As a result, the WSC had been subject to dozens of violations and ongoing enforcement actions. 

On September 24, 2020, the WSC and the Authority entered into an operations and management agreement. As part of that agreement, the Authority began managing the affairs of the WSC, including all operational aspects of the water system. 

After a unanimous vote by Prairie Grove’s voting membership, on November 23, 2020, the Authority formally began the process to acquire the WSC, confirming the community’s desire for a more stable and reliable water system. 

After a 22-month regulatory process, the Authority completed the acquisition process with the Public Utility Commission of Texas (PUC). In July 2022, Prairie Grove WSC officially joined the Authority’s family of utilities, under the new name Prairie Grove Utilities.

Since that time, the Authority has restored the system to a stable operational state, with plans underway to further increase water quantity and quality, as well as upgrading water distribution lines to meet demands for this growing community.

Prairie Grove Utilities – Extreme Winter Weather Update #13

Update 7pm Tuesday: Since 4pm, the demand has continued to be reasonable, so we’re going to leave the system on. We intend to read meters tomorrow. Our crews have already looked at just about every meter in the system, but a full meter read will help us find any smaller leaks that might remain. We hope to be able to lift the boil water notice at some point tomorrow as well. Thank you again for your understanding, patience, encouragement, and good attitudes as we went through this at seemingly the most inconvenient time possible. Have a good night, and if...

Prairie Grove Utilities – Extreme Winter Weather Update #12

Update – 4:00 p.m. Tuesday: The news so far today is good.  We began this morning with full tanks as hoped, and as of 3:30 p.m., we’ve only dropped by 11%. Dropping at all doesn’t sound great, but we expect some during the day because the well is undersized. It’s normal for usage during the day to outstrip the ability of the system to replenish, and it generally is able to catch up overnight when demand is at its lowest. The demand we’re seeing so far today is in line with an average day. So we believe most, if not...

Prairie Grove Utilities – Extreme Winter Weather Update #11

Update 7:45pm Monday: We’re going shut it down at 8 as planned. We will open it back up at 7am sharp, hopefully for the last time for this event. We’re seeing about the same draw as this morning after the leaks we know about were isolated, so at least we don’t appear to have any new leaks. Shutting it down one more time will allow us to start the day tomorrow with full tanks, and that should give everyone time enough to find those last few leaks. We don’t anticipate posting an update in the morning, since you’ll know when...

Prairie Grove Utilities – Extreme Winter Weather Update #10

Update 5:30pm Monday: As of 5pm, water is flowing once again. We intend to keep it open until 8pm as planned, then stop and let it replenish again overnight. Several customer side leaks were found this morning and fixed or the meters turned off. The draw on the system has improved considerably, but it’s still slightly more than the well can supply. With one more overnight replenish, we should be able to start the morning tomorrow with 100% full tanks. We believe there are still a few leaks out there. But if we and/or the homeowners with leaks are able...
