Segment 3-A1 Update

The Surface Water Supply Project is currently advertising the Segment 3-A1 Construction Project. Work of Contract is construction of approximately 14,000 linear feet of 42-inch diameter waterline with all necessary valves and appurtenances, along a CenterPoint Energy powerline corridor from south of Clay Road to the connection to Segment C located north of Tanner Road. The proposed water line installation will consist of primarily open cut construction; however, trenchless methods are required at crossings of HCFCD facilities, City of Houston (COH) roads, CenterPoint Energy Overhead Power Towers, and crossing of private/public utilities. Additionally, the Work requires installation of air valves, butterfly valves, pre-cast concrete manholes, and cathodic protection facilities, and removal and replacement of existing fencing and pavement surfaces (concrete, asphalt, and gravel).

Sealed Bids, addressed to West Harris County Regional Water Authority, will only be received electronically using the “E-Bidding” function on the CivcastUSA website ( until 2:00 PM, Local Time, March 18, 2021 for “Construction of Segment 3, Contract S3-A1 for the West Harris County Regional Water Authority (WHCRWA), Harris County, Texas.” More information is available at

Ensuring reliable, long-term water supplies for west Harris County and north Fort Bend County, Texas

The Surface Water Supply Project

To meet the Harris-Galveston Subsidence District (HGSD) and Fort Bend Subsidence District’s (FBSD) groundwater reduction requirements for 2025 and beyond, the West Harris County Regional Water Authority (WHCRWA) has partnered with the North Fort Bend Water Authority (NFBWA) to construct the Surface Water Supply Project.

Once complete, surface water from Lake Houston will be supplied to retail water providers (MUDs, PUDs, WCIDs, etc…) in the WHCRWA and NFBWA by way of the City of Houston’s Northeast Water Purification Plant through through over 55 miles of pipeline and two large pump stations. These transmission pipelines will vary in diameter from 96 inches to 42 inches, depending on the pipeline segment.

Opportunities for Outreach

The Surface Water Supply Team provides multiple opportunities for you to receive information about the Project. You may email us at or call our project hotline at 1-844-638-SWSP (7977) for updates. We are available to provide presentations to your local organization (meeting in-person or virtually), as well.

COVID-19 Update and Resources

The WHCRWA and NFBWA have received a number of questions regarding the impact of COVID-19 on water supply. The Center for Disease Control (CDC) has issued a statement that the COVID-19 virus has not been detected in drinking water, and conventional water treatment methods that use filtration and disinfection, such as those utilized in the WHCRWA and NFBWA’s systems, should remove or inactivate the virus that causes COVID-19.

The WHCRWA and NFBWA’s operator, Inframark, has compiled a variety of resources to assist answering questions related to the impact of COVID-19 on drinking water, which are available at The WHCRWA and NFBWA teams will continue to actively monitor any developments and update this information as needed.

Introducing the Surface Water Supply Project.

What to expect during construction.

The Mandate

The groundwater withdrawal in Harris and Galveston counties is regulated by the Harris-Galveston Subsidence District (HGSD), a special purpose district created by the Texas Legislature in 1975 for the purpose of reducing land subsidence.

The HGSD requires all water suppliers in Harris and Galveston counties to reduce groundwater pumping based on the rate of subsidence in their area. In the HGSD regulatory areas map shown, areas 1 and 2 have already converted to surface water. Area 3 requires conversion to alternate water via a 30% reduction of groundwater usage by 2010, 60% by 2025, and 80% by 2035.

HGSD and FBSD Regulatory Areas
30% reduction of groundwater usage by 2010
60% reduction of groundwater usage by 2025
80% reduction of groundwater usage by 2035


Construction will begin in early 2020. Contractors are currently conducting survey work and preparing for the start of construction. Although no pipeline segment will be affected for the entire three-year construction phase, construction is expected to be completed by 2025.
