Rainwater Harvesting Tanks, Pumps, and Filters in Atlanta, Georgia

Residential Rainwater Harvesting

Georgia Water Tanks is a manufacturer's rep company, providing water tanks, pumps, and filters on commercial and residential projects.

We were founded January 2014 with the goal of making rainwater harvesting a part of every construction project where stormwater management is required. As we grow, we look for ways to leverage our manufacturers' capabilities in all markets we serve.

Our goal for every project is to "make it work the way everybody thinks it should." To that end, we provide design assistance, custom coordination drawings, and commissioning on all our rainwater packages. More than commissioning, we provide jobsite supervision, to help all trades learn this "new" concept.

Don't rely on sizing based on rooftop area. They are based on rainfall rates in Europe, and do not account for thunderstorms like we have in Georgia. Use our tools instead.

This one was small enough that a day tank was unnecessary. What we call the "straight shot" design is appropriate up to 50 - 100 GPM. The limiting factor is how well the UV handles heat during periods of inactivity. As the UV manufacturers move to LED bulbs, we expect them to do a better […]
