Water Supplies for Sprinkler Systems

Embankment-supported fabric tanks can also function as suction tanks. The tank is usually composed of a reservoir liner with an integral flexible roof. A specifically prepared excavation supports the tank with embankments of earthen berms.

Tank capacity ranges up to 1,000,000 gallons in increments of 100,000 gallons. The tank can be located underground with the top of the tank at grade level or above ground with the earthen berms supporting the entire tank.

To prevent freezing, many of the tanks use a water recirculation system with a heat exchanger.
