In keeping the cost of Authority water as low as possible for as long as possible, there will be no rate increase in 2023. Water rates will remain $4.60/1,000 gallons for Groundwater and $5.05/1,000 gallons for Surface Water.

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

Pumpage Fee Information

Current Rates*

Groundwater – $4.60/1,000 gallons and
Surface Water – $5.05/1,000 gallons

*Some utility districts modify the NHCRWA water pumpage fee charged to their customers to cover such things as leaks in their system, fire hydrant use, etc.  Which will make the NHCRWA fee on your water bill higher than what the Authority actually charges.

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 $9.80 per 1000 gallons disincentive fee instead of the NHCRWA’s $4.60 per 1000 gallons water pumpage fee.

Surface Water Conversion

NHCRWA delivered approximately 28.9 MGD of treated alternative water in Sept 2022

Municipal Utility Districts participating in the groundwater reduction program
Miles of new waterlines installed in 2010 conversion
Miles of new waterlines constructed for 2025 mandate
Pump stations. SH 249 regional pump station is now under construction

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

To date NHCRWA has:

  • Designed, purchased easements for and constructed over 335 miles of new waterlines to comply with 2010 mandate
  • Constructed over 75 miles of additional waterlines for the 2025 mandate
  • Constructed Louetta Road Pump Station #1
  • Constructed Spears Road Pump Station #2
  • Began construction on a third regional Pump Station on State Highway 249
  • NHCRWA has converted and is delivering approximately 30 million gallons per day (MGD) of surface water to 57 districts
  • Partnered with the City of Houston on construction of the Greens Road Waterline that saves the Authority ~$15 million
  • Partnered with other regional water authorities to acquire, treat and deliver an additional 450 MGD of treated surface water
