The West Harris County Regional Water Authority (WCHRWA) was created by the 77th Texas Legislature to facilitate the shift from pumping underground well water to surface water in west Harris County.

In compliance with mandates issued by the Harris-Galveston Subsidence District (HGSD), the WHCRWA has:

  • Completed its Groundwater Reduction Plan certification
  • Successfully negotiated a long-term water supply contract with the City of Houston
  • Designed and constructed the transmission and distribution infrastructure to deliver surface water by 2010
  • Achieved the 30% groundwater reduction goal mandated by HGSD by 2010

WHCRWA is on track to comply with the HGSD groundwater reduction to 60% surface water by 2025, and 80% by 2035.

In 2020, WHCRWA was 35% converted for the permit year, with every gallon over 30% contributing to over conversion credits.

To date the WHCRWA has:

  • Designed, purchased easements for and constructed over 79.8 miles of new waterlines
  • Constructed WHCRWA Pump Station #1
  • WHCRWA delivers approximately 28 million gallons per day of surface water to 67 water plants
  • Converted 46 districts to surface water
  • Partnered with other regional water authorities to acquire, treat and deliver an additional 320 million gallons a day of treated surface water
    • The Luce Bayou Interbasin Transfer Project
    • Northeast Water Purification Plant Expansion Project
    • Surface Water Supply Project

Luce Bayou Interbasin Transfer

Luce Bayou Interbasin Transfer

The City of Houston, WHCRWA, NHCRWA, NFBWA and the CHCRWA have teamed up to initiate the Luce Bayou Interbasin Transfer Project with the capacity to bring nearly 450 MGD of raw water from the Trinity River to Lake Houston and the City’s North East Water Purification Plant (NEWPP).

NE Water Purification Plant Expansion

Northeast Water Treatment Plant

With the availability of more raw water coming into the Lake Houston reservoir, there was an urgent need for additional treatment capacity. The NEWPP project will be completed in phases over the next 6 to 9 years, increasing the treatment capacity from the current 80 MGD to a total of 400 MGD.
