In response to a mandate issued by the Harris-Galveston Subsidence District (HGSD) to increase usage of surface water and decrease groundwater use, Houston Public Works created the Surface Water Transmission Program (SWTP). To aid in preventing future ground subsidence and alleviate infrastructure damage and flooding, the SWTP Program goals are to increase surface water usage, decommission and/or minimize the use of groundwater pump stations, increase water system pressures and address other large-diameter water line issues.
