Rainwater Collection is Viable Alternative to Well Water

rural residential rainwater harvestingRural residents are finding that rainwater collection can be a viable alternative to well water.  Since rainwater is generally cleaner than surface water and well water, a rainwater system that is properly designed and installed can supply a household with good, clean water for potable use.

In a residential setting, the average person uses 30 to 50 gallons per day.  For a 2-person household, that would be 3,000 gallons per month.  A 2,000 sq ft roof will yield over 44,000 gallons of rainwater with 36 inches of annual rainfall, which is more than enough to supply a residence.

The screen is easily removed for periodic cleaning.

During pollen season, a layer of cheesecloth or a manufactured cloth filter liner should be installed to keep pollen out of the storage area. Both cheesecloth or the cloth filter can be rinsed and reused many times before a replacement is needed.

vortex filterA vortex filter for underground transfer from gutter to a sump tank is a good way to remove debris before rainwater is pumped to the cistern. Only periodic cleaning of the vortex filter is needed. Vortex filters should meet the roof size requirements to work effectively and installed per the manufacturer’s recommendations.
