Leonard Water Treatment Plant

Construction on the Leonard Water Treatment Plant started in the fall of 2018. “Raw” or untreated water from Bois d’Arc Lake will enter the treatment plant after traveling southwest through 35 miles of pipeline. The water will be treated using state-of-the-art ozone and biological filtration technology. Six massive pumps will propel the water from the Leonard Treated Water Pump Station through a distribution system to NTMWD member and customer cities. When initially complete in 2022, the plant will be able to provide up to 70 million gallons daily (MGD).

During Major Phase I construction, crews are building:
  • A 210-million-gallon terminal storage reservoir.
  • A high service pump station initially capable of pumping 90 MGD.
  • Biologically active filtration and ozonation water treatment facilities.
  • Access roads to the site, connecting power and water and building maintenance facilities.
Future site additions will include:
  • A second 210-million-gallon terminal storage reservoir.
  • A second high service pump station (for a total pumping capacity of 330 MGD).
  • Expansions of the treated water pump station (increasing pump capability up to 280 MGD).
