San Antonio Water System uses drought restrictions, established by city ordinance, to proactively manage the region's water resources. The restrictions limit water use based on specific levels of the Edwards Aquifer.
In 2013, an update to the ordinance was approved to help better align conservation goals with population growth and long-term water supply strategies.
Year-Round watering restrictions are in effect when the Edwards Aquifer level is above 660 feet mean sea level at the monitored well.
Stage 1 begins when the aquifer level reaches 660 feet mean sea level at the monitored well.
Stage 2 begins when the aquifer level reaches 650 feet mean sea level at the monitored well. Watering with an irrigation system or sprinkler is allowed only once a week from 7-11 a.m. and 7-11 p.m.
Stage 3 begins when the aquifer level reaches 640 feet mean sea level at the monitored well. Landscape watering is allowed only EVERY OTHER WEEK, from 7-11 a.m. and 7-11 p.m.
