Sources of Supply

Historically, the City obtained nearly all of its water from the Edwards Aquifer. The Edwards Aquifer lies beneath the City of San Antonio with an area approximately 3,600 square miles in size. Including its recharge zone, it underlies all or part of 13 counties, varying from five to 30 miles in width, and stretching over 175 miles in length, beginning in Brackettville, Kinney County, Texas in the west and stretching to Kyle, Hays County, Texas in the east. The Edwards Aquifer receives most of its water from rainfall, rivers, and streams flowing across 4,400 square miles of drainage basins located above it. The quality of the water surpasses all federal drinking water standards and requires only gas chlorination before distribution. In 2002, fluoride began to be added to both SAWS and Bexar Metropolitan Water District’s water supply after a city ordinance was passed.

In the past two decades, SAWS has begun to diversify its sources of supply. In 2012 only 46% of San Antonio’s water came from the Edward’s Aquifer, compared to over 70% in 2000. SAWS’s other water sources include supplies from Canyon Lake, the Trinity Aquifer, the Carrizo Aquifer in Bexar County, and the Carrizo Aquifer in Gonzales County. Being able to draw on multiple, diverse sources of water allows San Antonio to deal with droughts and cope with dramatic population growth without endangering the region’s water resources.

In 2012, SAWS updated its Water Management Plan to outline a diversified foundation of San Antonio’s water supply through the year 2070. While the Edwards Aquifer will always be the cornerstone of San Antonio’s water supply, SAWS is continuing to develop alternate sources to meet the needs of a burgeoning metropolitan population. SAWS has highlighted a number of key projects in the short term (through 2030) to meet the growing demand for water in San Antonio. One critical piece of the puzzle is the Brackish Groundwater Desalination Program, which will draw previously unusable water from the Wilcox Aquifer (located south of San Antonio). Construction on SAWS’s first desalination plant will be complete by 2016. SAWS hopes to be able to pump as many as 30,525 acre-feet of water from the Carrizo Aquifer annually by 2026. Development of this new water source will diversify SAWS water resource portfolio with a wholly new, sustainable, drought-proof supply, without directly competing for access to freshwater resources with neighboring water users.

The 2012 Water Management Plan also outlined concepts for long term projects (past 2030) to protect and expand San Antonio’s access to water, including desalination of ocean water from the Gulf of Mexico and expansion of SAWS’s Aquifer Storage and Recovery Program, which capitalizes on the natural storage capacity of the Edward’s Aquifer to give San Antonio the tools to manage water resources in drought conditions.

Vista Ridge Pipeline in 2020

The Vista Ridge Pipeline, scheduled to deliver water here in 2020, will provide the largest, non-Edwards Aquifer water supply to our region — enough for 162,000 new families. San Antonio Water System (SAWS) officials estimate an increase of 20 percent more water for San Antonio.

The Vista Ridge pipeline will consist of 142 miles of pipe running between Burleson County and Bexar County and will pull 50,000 acre-feet of water from the Carrizo-Wilcox and Simsboro Aquifer by 2020. Combined with the unmatched conservation already exhibited by San Antonians, SAWS’ foresight to establish water storage facilities, and desalination and other new water supply initiatives, San Antonio’s water needs should be addressed for generations to come. San Antonio will soon be recognized as a viable option for water intensive operations that are considering expansion or relocation.

Conservation Program

As a result of a nationally recognized conservation program, SAWS is using the same amount of water today as it did more than two decades ago, despite a population increase of 67%. Given these accomplishments, the 2012 Water Management Plan includes goals of 135 gallons per capita per day (GPCD) by 2016. SAWS has a unique commercial conservation program as well as a strong residential program, such as direct rebates and services to help customers reduce water use, certification programs for industry, and public education programs for the entire community.

Water Recycling Program

SAWS provides high quality recycled water from its wastewater treatment plants to augment, and in some instances replace, Edwards Aquifer water for industrial, commercial and irrigation use. The water recycling program is designed to provide up to 35,000 acre-feet per year of recycled water. Currently, more than 130 miles of pipeline deliver highly treated effluent to approximately 60 customers consisting of golf courses, parks, and commercial and industrial customers throughout the city. Recycled water is one of the key factors in making more water available for economic growth and development in San Antonio.

Water Distribution System

Currently, SAWS maintains almost 5,100 miles of distribution mains, ranging in size from four inches to 60 inches in diameter, the majority of which are between six inches and 12 inches in diameter.

Fast Facts

Pumping Capacity: 826.2 million gallons per day (MGD)

Average Pumping Rate: 195.22 MGD

Peak Pumping Rate: 299.1 MGD

Underground Storage Capacity: About 120,000 acre feet or more of excess Edwards Aquifer water

Reservoir Capacity: 192 million gallons in 42 elevated storage tanks and 38 ground storage tanks

Education Program

SAWS Education offers a variety of ongoing programs and activities to meet the varied needs of San Antonians. The goal is to develop a water-literate society and to inspire future generations of active water stewards.

SAWS Education has established its own custom youth education curriculum for pre-kindergarten through 12th grade. The program is designed to inspire students to take an active interest in water issues. Students discover the science of water right along with their ABCs in elementary school. In middle school and high school, students learn how to apply that instruction through field studies and experiments.

Teachers at all grade levels receive comprehensive training and materials from SAWS on various water subjects to use in their classrooms. Community field trips and outreach events extend water education beyond the classroom to adults by providing an in-depth look at SAWS water and wastewater functions.

Wastewater System

The wastewater system is composed of about 5,150 miles of sewer mains and three major treatment plants: Dos Rios, Leon Creek, and Medio Creek. All three plants are conventional activated sludge facilities. SAWS holds Texas Pollutant Discharge Elimination System (TPDES) wastewater discharge permits, issued by the TCEQ for 233 MGD daily average flow.

Regional System

San Antonio operates a regional sewage system serving Bexar County. SAWS provides sewage service to all properties within the city’s legal jurisdiction with the Regional Boundaries according to the provisions of Chapters 34 and 35 of the City Code. Impact fees are charged on all newly planted properties serviced by the Regional System. Adequate main and treatment plant capacity is assured to users of the Regional System.


The San Antonio federally approved Industrial Pretreatment Program requires certain industrial and commercial facilities to have an Industrial Water Permit. Some industries regulated by the San Antonio Water System are required to pretreat their effluent prior to discharge.

Capital Improvement Program

The Capital Improvement Program (“CIP”) is a multi-year plan for implementing projects that support water supply and delivery, wastewater collection and treatment, and heating and cooling needs in the SAWS service area. The CIP is a financial planning and management tool that identifies facility and equipment requirements, and schedules them for funding and implementation.
