// Strategic Significance
Houston's water system serves 2.3 million direct customers drawing from Lake Livingston Lake Conroe and the Trinity and San Jacinto Rivers. Hurricane Harvey in 2017 overwhelmed multiple water treatment facilities causing boil water notices for millions of residents for days after the storm. The system's vulnerability to flooding was starkly demonstrated — entire treatment plants were inundated making water treatment impossible while residents had the greatest need.
// Civilian Impact Assessment
Harvey demonstrated that Houston's water treatment infrastructure is highly vulnerable to the same flooding that affects residential areas. Multiple treatment plants were flooded simultaneously leaving millions without safe drinking water for extended periods. The system serves the 4th largest US city and failure during a major hurricane creates a compounding survival emergency during already life-threatening conditions.
// Evacuation & Shelter Guidance
Houston residents should maintain minimum 2 weeks of water storage given demonstrated flooding vulnerability of the treatment system. During major hurricanes water treatment may fail before or simultaneously with evacuation decisions. Maintain water filtration and purification capability. Monitor Houston Water emergency broadcasts. After Harvey prioritize water before other supplies in emergency planning.
