Groundwater Withdrawal in Harris County
The groundwater withdrawal in Harris County 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 the WHCRWA to convert to alternate water via a 60% reduction of groundwater usage by 2025, and by 80% by 2035.
