Should I Use a Pillow Tank or Liner for my Cistern?
Rainwater Collection Tank
Pillow Tank vs. Liner
I have a metal tank (92" Height x 200" Diameter) it is outside and was wondering if I should use a pillow tank instead of a liner.
The tank is outside now but will be under house when I build it. I'm going to need a lid on the tank but then I thought about just using pillow tank. Can the pillow be cleaned? How would fittings be used?
Thanks for contacting the Portable Tank Group. Choosing between a Pillow Tank and a liner for your cistern is a common debate. They both accomplish the same goal, but in different ways.
Both the pillow style tank and the liner are manufactured with fabrics that are FDA and NSF 61 compliant for potable water use. They both also perform well under seismic conditions and are relatively cost effective and easy to use.
The fittings on the tank can be placed where you need them, according to your configuration. Standard fittings are 3/4" thru 2" and we have 4" thru 6" available upon request. Choose from Aluminum, Stainless steel, Polypropylene with Camlock, Storz or threaded fittings to accommodate hoses. Also available are ball valves, pressure relief vents and caps. The fittings will allow you to hook up hoses and pumps to have access to the water you are storing.
The pillow tank can be cleaned. Chlorine can be used, and we recommend a solution at no more than 5%. An alternative means of sanitation is with an industry approved sterilizing agent. There are a number of suitable options available from the Ecolab Center.
