Conservation Ordinance

In 2013, an update to the ordinance was approved to help better align conservation goals with population growth and long-term water supply strategies.

Because of San Antonio's conservation success, as well as the availability of new supplies, SAWS has made revisions to the city's drought ordinance. These changes will continue to build on our community's water-wise ways to reach even greater savings. Residents will have more opportunities to achieve those results without compromising landscapes by participating in effective residential and commercial conservation programs.

Highlights of the 2013 Conservation Ordinance update include:

  • Sprinkler use allowed 7-11 a.m. and 7-11 p.m. on your watering day in drought Stages 2 through 4. The hours for Year-Round and Stage 1 remain the same as they are now.
  • All residential fountains can operate at any stage of drought.
  • Home car washing allowed during drought once per week on Saturday or Sunday as long as there is no water waste.
  • Hand watering still allowed any day and time during all drought stages.

For Commercial customers:

  • All indoor commercial fountains can operate at any stage of drought.
  • Outdoor commercial fountains must have a SAWS variance in order to operate during drought Stages 1 through 4.
  • Existing cooling tower owners shall register their tower with the SAWS Conservation Department by May 1, 2013. New cooling tower owners shall register their towers prior to the start of operation.

Adopted by the SAWS Board and City Council, the rule changes are effective Feb. 18, 2013.
