Where Does Our Water Come From?

SJRA’s Woodlands Division provides water through groundwater wells designed to produce water from the Evangeline and Jasper aquifers and treated surface water from SJRA’s Groundwater Reduction Plan Division.

  • Groundwater Wells-Some of these wells have been producing water since 1973 and have drill depths as deep as 1,700 feet below ground level.

  • Treated Surface Water-Surface water from Lake Conroe (and possibly other surface water sources) is pumped into the SJRA’s 30 MGD Surface Water Treatment Plant to go through a robust treatment process, delivered through 52 miles of water transmission line, and blended with groundwater in existing ground storage tanks.
