2017 Rate Address Infrastructure, Water Supplies

A rate adjustment of $3.79 — or a 6.8 percent increase on the average residential water and sewer bill (not counting regulatory pass-through charges) — is scheduled to take effect Jan. 1, 2017. Due to additional efficiencies, SAWS was able to keep the adjustment below the 7.9 percent maximum authorized by City Council in November 2015.

What the Rate Adjustment Will Pay For"We always strive to make SAWS more efficient," said President/CEO Robert R. Puente. "This is how we were able to keep the adjustment lower than expected."

The majority of new revenue will pay for capital improvements, sewer system upgrades required by the U.S. Environmental Protection Agency and longterm water supplies. This includes the new desalination plant as well as infrastructure to distribute water from the Vista Ridge project starting in 2020. Both projects further diversify San Antonio's water portfolio beyond the drought-sensitive Edwards Aquifer.

New rates will be reflected in February 2017 bills. To see how your own bill will change, use the rate calculator at

Former BexarMet Areas to Receive First Water Rate Adjustment in 7 Years

Customers in former BexarMet service areas will see water rate adjustments for the first time since 2010.

Now that the former utility has been fully integrated into SAWS, customers in those areas will begin paying SAWS rates for water service beginning in January 2017.

The average residential customer in former BexarMet areas will see an increase of 7.8 percent in their monthly water and sewer bill. However, customers who use 2,992 gallons a month or less will see a decrease of more than 3 percent, thanks to the SAWS "lifeline" rate. (These adjustments do not include regulatory pass-through charges.)

These customers will also be eligible for SAWS payment assistance programs, including the Affordability Discount, beginning in 2017. This SAWS program could offer substantially more direct financial assistance than under the former utility. SAWS' Affordability Team can be reached at 210-233-CARE (233-2273).

New rates go into effect Jan. 1, 2017, and will be reflected in February bills.
