UTILITY HISTORYHighland Park water: from town wells to a Park Cities plant
After incorporating, Highland Park set up its own waterworks and ran them until 1932. From 1932 to 1950 it bought water from Dallas. In 1950 Highland Park and University Park opened their own Park Cities waterworks, and the Park Cities helped pay for the Garza-Little Elm reservoir, now Lewisville Lake, in exchange for water. Today the town buys from the Dallas County Park Cities Municipal Utility District, which takes surface water from Grapevine Lake by way of the Elm Fork of the Trinity River. Two connections to Dallas Water Utilities serve as backups.

04 / THE SOURCE MATTERS
A clear paper trail.
Research checked November 3, 2026. This date is not a sample date. Original reports are unchanged.
Highland Park delivers water treated by the Dallas County Park Cities Municipal Utility District (TX0570078) from Lake Grapevine at its Regal Row plant; it is not Dallas Water Utilities water. EWG is the primary source for this city record. Each result retains its data period and source; supplying-utility results are identified separately. Municipal report results supplement topics where no EWG result is available.
