Securing a long-term, reliable supply of wholesale drinking water while keeping the cost of water as low as possible for as long as possible.

On June 18, 1999, the bill (HB 2965) that created the North Harris County Regional Water Authority (NHCRWA) was signed into law, and called for a special election to be held on January 15, 2000 so voters could confirm the creation of the new Authority and elect Directors to lead it.

Following the election, NHCRWA became the single entity empowered to negotiate for a secure, long-term, reliable, quality supply of wholesale drinking water for all the independent neighborhoods, municipal utility districts, small municipalities, and permitted well owners within its boundaries.

NHCRWA’s primary assignment is to develop and implement a strategy for complying with the Harris-Galveston Subsidence District’s (HGSD) Regulatory Plan that requires a conversion from groundwater to alternate water via a:

30% reduction of groundwater usage by 2010
60% reduction of groundwater usage by 2025
80% reduction of groundwater usage by 2035

Since the Authority is not a taxing entity, funding for our future water supply and the infrastructure through which to deliver it is being accomplished through the sale of revenue bonds, and paid for by revenue from groundwater pumpage fees and water sales.

In compliance with mandates issued by the HGSD, NHCRWA has:

  • Completed its Groundwater Reduction Plan (GRP) 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
  • 143 MUDS have entered into an agreement to participate in the authorities GRP

If Municipal Utility Districts in Harris-Galveston Subsidence Regulatory (HGSD) Area 3 DID NOT convert to surface water as mandated by the Texas Legislature, water users in those districts would be forced to pay the HGSD’s $11.86 per 1000 gallons disincentive fee instead of the NHCRWA’s $3.60 per 1000 gallons groundwater pumpage fees.


Groundwater $3.60 /1000 gallons
Surface Water $4.05/1,000 gallons
