San Antonio Enters Stage 1 Drought Restrictions

Edwards Aquifer level triggers EAA-required cutbacks and watering rules

San Antonio has not experienced drought restrictions since October 2017, but despite the recent rain, the 10-day average at San Antonio's monitoring well has dropped to 658.5, requiring a return to Stage 1 water restrictions effective Monday, May 21.

Per City ordinance, City Manager Sheryl Sculley in consultation with Robert R. Puente, president/CEO of San Antonio Water System, declared Stage 1 management rules are in effect.

Stage 1 of the city's drought plan is triggered when the 10-day average of the Edwards Aquifer at the J-17 monitoring well drops to 660 feet or below. According to the city's Aquifer Management Plan ordinance, coming out of drought stages can be considered 15 days after the aquifer is above the trigger.

"Despite the cooler weather and rain we've received this year the region's water use has driven aquifer levels to drop," Puente said. "We have an ample supply of water from the Edwards and several other sources, but state law requires us to cut back on pumping when the Edwards Aquifer reaches certain levels."

When in Stage 1, outdoor watering with a sprinkler or irrigation system is allowed only before 11 a.m. and after 7 p.m., one day per week, based on the last number of your address:

0 or 1 – Monday
2 or 3 – Tuesday
4 or 5 – Wednesday
6 or 7 – Thursday
8 or 9 – Friday

Watering days begin and end at midnight; overnight watering is not allowed. Water waste, such as water running down the street, is prohibited year-round. However, watering with a handheld hose is still allowed any day, any time.

SAWS offers its water customers $100 or $200 coupons to replace water-intensive grass with drought-tolerant garden beds or permeable patios. The coupons are available through May 31 so customers should act quickly to take advantage of the online offer at GardenStyleSA.com/coupons.
