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

Following the election, the Authority 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.

These boundaries are essentially US 290 on the west, the Harris County line on the north (Spring Creek), Cypress Creek Parkway and Bammel-North Houston on the south and the western shores of Lake Houston on the east. The Authority is comprised of 335 square miles and includes approximately 710,000 residents.

The Authority’s primary assignment is to develop and implement a strategy for complying with the Harris-Galveston Subsidence District’s Regulatory Plan that requires a reduction in groundwater usage to no more than 20 percent of total water demand by the year 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.

The Rising Cost of Water

How we started and where we plan to go

Reduction in groundwater usage

The Authority’s primary assignment is to develop and implement a strategy for complying with the Harris-Galveston Subsidence District’s Regulatory Plan that requires a reduction in groundwater usage.

The Subsidence District’s regulations require conversion to alternate water via a 30% reduction of groundwater usage by 2010, 60% by 2025, and 80% by 2035.

In addition to the cost of purchasing the surface water from the City of Houston, there are shared transmission, operations, and maintenance expenses to be paid. All of these factors, coupled with the cost of constructing the NHCRWA’s, 2025 water supply system, will impact the future cost of water.
