Fact Sheet: Trinity Aquifer Project
(2/25/02)
Some San Antonio Water System customers who live and work in far northern San Antonio began receiving water from the Trinity Aquifer Feb. 25, 2002. Here are some basic facts about this new source of drinking water for SAWS customers:
-
SAWS signed contracts in February 2000 with the Massah Development Corporation and the BSR Water Supply Company to purchase water from public supply wells completed in the Trinity Aquifer system.
-
The source of the water comes from the Trinity’s Lower Glen Rose and Cow Creek formations.
- Initially, water will be pumped directly to the 3.2-million-gallon Indian Springs water storage tank near Bulverde and Smithson Valley roads to be chlorinated and placed into SAWS system.
-
Later, a new 5-million-gallon water storage tank, jointly constructed and shared by SAWS and BexarMet, will be built on Oliver Ranch and added to the system.
- This marks the first time San Antonio Water System customers will receive drinking water at their tap other than Edwards Aquifer water.
- At start up, about 750 households and businesses, in an area north of 1604 and east of 281 (see map), will be receiving Trinity Aquifer water.
- Initially, the project will produce about 815 million to 945 million gallons (2,500 to 2,900 acre feet) of water annually; however, studies predict the project will yield about 2 billion gallons (6,200 acre feet) each year.
- Trinity Aquifer system water is naturally fluoridated at about 0.7 parts per million, which is within the level recommended by national standards.
-
The capital cost of project was about $5.5 million or about $425 an acre-foot per year.
