About Us

At Rural Water District No. 1 Ellsworth County, Kansas, our goal is to provide safe, clean, reliable water to all of our residents!

Rural Water District No. 1, Ellsworth County, Kansas a/k/a Post Rock Rural Water District was first organized in 1979 by a group of farmers in the Wilson area who were searching for a safe and reliable source of water. The District now serves water directly in segments of eight counties and indirectly to two more counties, through over 1500 retail customers and 10 wholesale accounts.  Post Rock RWD's sole source of water is Kanopolis Lake which is fed by the Smoky Hill River.  The lake is a good supply for the system.  The protection and preservation of this precious resource is essential.  Post Rock RWD's treatment plant currently has the capacity to produce 1.1 million gallons of water per day.  Water is stored in a 200,000 gallon underground clear well for distribution to the system.  The finished product is distributed to Post Rock's customers through approximately 1,800 miles of pipeline.
