Houston Drinking Water Overview
Population: ~2,300,000 | Source: Lake Houston, Lake Livingston, and groundwater
Houston's water comes from a mix of surface water and groundwater, managed by the city's Public Works Department. The Houston Ship Channel and surrounding petrochemical industry create a complex contamination landscape. Flooding events can overwhelm treatment systems and cause boil water advisories. The city has been shifting from groundwater to surface water to reduce land subsidence.
