ALTERNATIVE WATER SOURCES
Supplement a water well system with an alternative water source like rainwater harvesting. Well water is dependent on so many factors that can impact the availability, quality, and overall drinkability.
Having an alternative water source can act as a backup, or help to alleviate well water dependence.
Utilizing an alternative water source can be as easy as connecting an existing gutter system to a tank and using the same existing well system plumbing. Rainwater systems may also have financial incentives depending on the location of the project.
The State of Texas, for example, has a sale-tax exemption for rainwater system components including the rainwater storage tank. (Learn More)
RESOLVING WELL WATER ISSUES
Water wells that aren’t able to provide a consistent clean water supply can be resolved with an alternative water source. Drilling a deeper well can be very expensive, especially as compared to adding a rainwater catchment system as a water source.
Rainwater is naturally soft water that typically has nearly a neutral pH for easy filtration. Rainwater systems are designed to accommodate the water used for the household or property and can be added to an existing well system.
Since different water sources may require different filtration, the water needs to be thoroughly tested to see if they can be combined or need to be stored in separate tanks.
TURN A ROOF INTO A WATER SOURCE
The amount of potential rainwater that can be collected depends on the rooftop catchment area space and the amount of rainfall that falls annually.
The typical calculation is as follows:
Catchment Area (ft^2) X Rainfall depth (inches) X 0.623 (Conversion Factor) = Potential Harvested Rainwater (Gallons)
