At RainKeepers, we offer two primary types of tanks:

Poly and Corrugated Metal


Metal Tanks

Very aesthetically pleasing

Can be painted to match color of home

Has potable, food-grade liner

30 degree, 10 degree, domed, or flat roof options

Larger capacity options (8,000 – 100,000 gallons)

Poly Tanks

More economical option

Good for applications where aesthetics isn’t important

Provides more flexibility to customize where inlets/outlets are located

Darker colors inhibit algae growth by reducing UV penetration

Can be used for potable or non-potable collection
