All should have a UV protection warranty for at least 8 years. Dark colors are recommended to alleviate light penetration which can cause algae growth. Multiple tanks can be manifolded together to achieve the volume of storage needed. Keep in mind that plumbing should be under ground for frost protection.

There are vertical cylinder plastic water tanks if you have a large area for storage. Slim line design plastic water tanks are best suited for urban settings where space is an issue. There are box type plastic water tanks for storage under decks.

All rainwater storage tanks should be NSF approved for drinking water, should you decide to go potable now or in the future. There is a tank that will fit every application.

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.

Steel and plastic water tanks are economical to install when considering the cost of a having a drilled well.
