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 an approximately 35-mile-long pipeline and two large pump stations. The pipelines will be 7 to 8 feet in diameter depending on pipeline segment.

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

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 2023.
