Rainwater not Desalination

Conventional wisdom is that people use about 100 gallons per day of water. My family averages less than 50, but maybe 100 GPD includes water use embedded in things we buy or use. About 350,000,000 people live in the USA. So adding the data on rainfall from this page, the Lower 48 receive about 100x the amount of water needed. That’s pure water desalinated and transported without any man made energy. Just need to be more efficient in collecting it.

That’s where rainwater harvesting comes in. Most every single-family home could collect enough water to meet the needs of the residents, especially when combined with graywater treatment and reuse. The technology is mature and reliable, and becoming more affordable every year. The process is specified in plumbing codes. The products are certified by independent third parties.

Rainwater Harvesting Grants for Nonprofits


The Community Foundation for Greater Georgia offers water (and energy) efficiency grants for nonprofits. The Grants-to-Green program has been very popular. It awards grants twice a year. For more information, click here: 

For religious organizations, Georgia Interfaith Power & Light, gipl.org, offers energy efficiency grants, but not for water. Yet! Please contact and encourage them here!

They also offer rainbarrel workshops. For more information, click here.  Here's hoping that they don't use translucent rain barrels anymore!

Rainwater Harvesting for Community Gardens

Another community garden is ready for the rain! We do some installations ourselves, but our goal is to teach contractors how to add rainwater harvesting to their portfolio of services.


Like many of these community gardens, this school takes water from a single downspout. A 4" pipe brings rainwater to an above-ground tank, which has a basket-style prefilter. Yes these require cleaning, but they are most popular. A typical rainstorm will fill the tank.

This project didn't use a pump, but most do.

Drought Returns to Georgia




This the current condition in Georgia. We are again in a Level 1 Drought as of September 2016. The area under Moderate Drought or higher has doubled from 20% of the state last year this time, to 40%. No additional watering restrictions have been added so far.

What should I do?

We all want nice green lawns, but grass is the most easily replaced part of the landscaping. It's more important to protect trees and shrubs. However, the condition of the grass is a good indication of the moisture available to all the landscaping, IF WE WATER EVENLY.  So when you water, cover the whole yard!

There are various methods for conserving water in irrigation: some use weather data downloaded from NOAA. Others measure sunlight intensity, temperature, humidity, and the presence of rainfall. Others use soil moisture content. We will be experimenting with this, but my preference is always a direct measure of the desired result. So, moisture sensors. However, sensor quality can be highly variable no matter what kind, especially something mass produced for consumers.

And of course, collect rainwater! If drought levels worsen, there's a real possibility of a total outdoor watering ban. How can a rainwater system help? Even the worst droughts in Georgia are a 50% reduction of rainfall. Which means that most buildings can double their effective rainfall with a rainwater system, which should be enough to protect trees and shrubs.

Please contact Georgia Water Tanks for help protecting your valuable landscaping. Our primary business is supplying equipment to contractors, with design assistance and on-site support during installation and commissioning included. If you are a property owner and are looking for an installer, we can recommend several that are experienced installers. And we are always looking to train more!
