What is the NHCRWA?

The North Harris County Regional Water Authority (NHCRWA) is a wholesale water provider created by the Texas Legislature and approved by voters in 2000. Its primary mission was to manage compliance with regulatory groundwater reduction mandates. It is not a retail water provider like a Municipal Utility District (MUD), nor does it have any oversight of MUD operations (e.g., delivering water to homes and businesses, sewer services, retail billing, etc.).

The MUDs that supply our neighborhoods with drinking water have traditionally pumped groundwater from individual wells drilled into the aquifers below. Dramatically increasing population and decades of aggressive water usage have caused the aquifers to decline, resulting in land subsidence and causing increased flooding.

In 1975, the Texas Legislature created the Harris Galveston Subsidence District (HGSD) and gave it the power to restrict groundwater withdrawals as a method to minimize subsidence and to help give aquifers an opportunity to recharge. The HGSD began its efforts in the Baytown Pasadena area, which proved to be extremely successful, and later extended its phased groundwater regulation to include north and west Harris County in 2000.

Compliance with the HGSD’s mandated conversion from groundwater to surface water to mitigate subsidence is being accomplished in phases:

30% reduction of groundwater usage by 2010

60% reduction of groundwater usage by 2025

80% reduction of groundwater usage by 2035

The initial mandate was met in 2010, which reduced reliance on groundwater in the area by 30 percent.*

*Failure to meet these deadlines would trigger a HGSD (“Disincentive”) penalty of $11.86/1000 gallons pumped, which is significantly higher than the NHCRWA water pumpage Fee.

If you are covered under the Authority’s Groundwater Reduction Plan, you will pay the fee below:

If the Authority was not created, all Utility Districts in Harris-Galveston Subsidence District Regulatory (HGSD) Area 3, if they are not in compliance, may be subject to the disincentive fee below:

Groundwater $2.60 /1000 gallons
Surface Water $3.05/1,000 gallons

$11.86 /1000 gallons

Q. Where does our surface water come from?

For the past two decades, the NHCRWA has partnered with the City of Houston and other area water Authorities to deliver available water supplies to where they are needed most. This involves constructing new pipelines and more infrastructure to receive and deliver water treated at the Northeast Water Purification Plant (NEWPP) to the MUDs/water providers within the Authority’s boundaries.

Q. How do we pay for converting to surface water?

The Texas Legislature did not give NHCRWA taxing authority when it was created. To generate sufficient revenue to cover debt service and pay operating and construction costs for the infrastructure already in the ground, the NHCRWA adds a usage charge for groundwater pumped by the utility districts and delivered to its customers, and for sales of surface water provided to the district.

The Authority has had numerous bond sales over the past 20 years to fund the 2010 distribution system and other construction and operating costs. As more bonds are sold to fund the 2025 conversion projects, the debt service will continue to rise.

The Authority has also had access to the State Water Implementation Fund for Texas. The NHCRWA has been one of the largest recipients of subsidized, multi-year funding through the SWIFT Program in the state! This will save the Authority’s rate payers millions of dollars in interest payments over the next 30 years.

Q. What is the NHCRWA Water Pumpage Fee on my bill?

NHCRWA does not bill any individual homeowner/customer for the water they use; that is the responsibility of the MUD – their retail water provider.

NHCRWA charges each MUD for the (metered) groundwater they pump from their well(s) and the surface water delivered to them by the Authority.

Rates effective 10-01-2024

Groundwater – $2.60/1,000 gallons and
Surface Water – $3.05/1,000 gallons

Based on meter readings, the District in turn applies the NHCRWA water pumpage fee to their customers’ bills based on how much water the customer uses, so the amount may change monthly depending on your water use.

*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.
