The Rain to Drain Experience


San Antonio Water System ensures you always have a safe, reliable and quality supply of water at every turn of the tap. If you’re interested in learning more about the source of your drinking water and where it goes, well, “after the flush,” join SAWS Education for The Rain to Drain Experience field trip for adults.

During this fully immersive day-long expedition, lasting from 9 a.m. – 5 p.m., you will travel to places few people have ever visited. You will explore an Edwards Aquifer recharge cave, experience the inner workings of a SAWS water production facility and tour a water recycling center.
