San Antonio Moves into Stage 2 Watering Rules

Spring’s rainy weather has turned into hot dry summer days, and today the 10-day average for the Edwards Aquifer dropped to 650.0 feet.

Per city ordinance, City Manager Sheryl Sculley in consultation with Robert R. Puente, President/CEO of San Antonio Water System, declared Stage 2 management rules are in effect.

The announcement comes as SAWS has encouraged residents to become involved in planning the city's water future by asking them to complete a short survey at SAWS is currently developing its 2015 Water Management Plan.

Stage 2 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 650 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.

“The Texas Climate includes extremes in weather,” said Robert R. Puente, SAWS President/CEO. “SAWS considers this in our water supply planning. Our alternative sources of water, like Canyon Lake and Carrizo Aquifer sources, have helped slow the decline in the Edwards Aquifer. These other sources, in addition to reasonable landscape watering restrictions, provide for San Antonio’s well-balanced response to the dry summer conditions.”


Watering days stay the same in Stage 2 as in Stage 1, however the hours during which watering is allowed are shortened. Watering with a sprinkler, soaker hose or irrigation system is allowed only during the hours of 7 to 11 a.m. and 7 to 11 p.m. on your designated day, as determined by the last number of your street address. Areas without a street address, such as medians and neighborhood entryways, water on Wednesday.

Watering days begin and end at midnight; overnight watering is prohibited. Watering with a handheld hose is still allowed any day, any time.
