What Storage is Best for a Rainwater Collection System?

buried tankStorage for domestic, household use (potable) is required by code to be NSF approved for drinking water. RainBank Rainwater Systems of Seattle recommends that any storage for residential systems meet this standard. An irrigation system can be converted to domestic use safely if the cistern is NSF approved.

Available space, along with aesthetics, should be considered in what type of water tank best suits the intent and design.

There are bladder-type pillow tanks that can be placed in crawl spaces or buried tanks that have zero visual impact. Bolted together, galvanized steel water tanks have a liner inside the tank, while the steel shell provides protection and structure for the liner. Polyethylene (plastic) water tanks are the most cost effective. Additional tanks can easily be added in the future. Slimline tanks or Box tanks can be used for limited available space applications.
