What Is This “RWA Fee”?


Understanding the Regional Water Authorities

Discerning residents may have noticed a line-item on their water bill titled “RWA Fee” or something similar. This is the fee collected by Memorial MUD and goes towards West Harris Co. RWA, the Regional Water Authority (RWA) in the area. Below is a brief description of what RWAs are and what they do.

On June 18, 1999, the bill (HB 2965) that created RWAs was signed into law by Texas State Legislature, and called a special election so voters could confirm the creation of a new authority and elect directors to lead it. The RWAs became 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.

Among the RWAs created was the North Harris County Regional Water Authority (NHCRWA). Resting within the Harris-Galveston Subsidence District (HGSD), known for the greatest impacted area of subsidence in Texas, the new authority faced an epic challenge: they must secure the future water supply, construct the new water delivery infrastructure, and generate the funding to accomplish it – all within a set timeframe. The enabling legislation also required the new agency to promote water conservation.

Following the lead of the NHCRWA, the West Harris County Regional Water Authority (WHCRWA) was created by HB 1842, approved by 77th Texas Legislature, and signed into law May 28, 2001. Like the NHCRWA, the WHCRWA was created to accomplish public purposes stated in the bill, including:

  • the provision of surface water and groundwater for various uses.

  • the reduction of groundwater withdrawals.

  • the conservation, preservation, protection, recharge, and prevention of waste of groundwater and of groundwater reservoirs.

  • the control of subsidence caused by withdrawal of water from those groundwater reservoirs.


As a result of the increasing threat subsidence posed to these areas, the HGSD adopted a series of regulatory plans to reduce groundwater pumpage, and ultimately mandated, in their 1999 plan, a reduction to only 20% reliance on groundwater by 2030. With the help of the NHCRWA and the WHCRWA, a fair and equitable contract with the City of Houston to supply surface water from Lake Houston was successfully negotiated and construction is already underway in both Authority areas. The goal of the HGSD is to see the same dramatic improvements occur in these areas as were experienced south and east of Houston years ago.

Resident Impact

All customers within the boundaries of the Authorities pay a fee as a line on their bill, which is collected by the individual water district that supplies them. This amount is then passed to the Authorities to fund water supply delivery infrastructure and groundwater conservation efforts; the projects and efforts to convert fully to surface water supply for the HGSD area are created through bonds, which these fees repay as they are collected.

The Authorities charge the water districts groundwater and surface water fees based on a Rate Order adopted by their respective Boards of Directors. These fees have funded construction of the initial infrastructure and will continue to cover debt service requirements and bond covenants, as well as to fund the maintenance and operation of the surface water delivery system and construction of future infrastructure.

The Authority fees are a necessary part of the cycle of water service and wastewater treatment. They fund the infrastructure that converts the area to utilizing more surface water and reducing subsidence in the HGSD. These efforts are all part of a larger conservation and sustainability goal set by the State Legislature of Texas.

Continued Growth

Conservation and sustainability efforts require time and money, along with a dedication to meet or exceed the goals set by entities like the HGSD. In the early 1900’s the greater Houston area did not expect or plan for the amount of growth and water requirements that would come with expansion in the 60’s through present day. The Regional Water Authorities are providing the ways and means to make sure water continues to flow and subsidence is abated as Houston and surrounding areas continue to grow.
