Silo FAQ's

Yes, Silo must be installed on a levelled concrete slab at least 100mm wider and longer than the tank or tank group.

Only simple, annual cleaning is required to maintain the Silo exterior. Use a soft bristled brush, water, or water mixed with a mild detergent to wash the plastic. When used to store non-potable water, the interior of the tank does not require any maintenance since the use of leaf guards etc. will remove vegetation before entering the tank.

It is probable that small amounts of dust or similar will enter the tanks, but the amounts will not impact on the storage or capacity of the Silo tank.

Yes, a tap can be installed near the base of the tank to gravity feed a tap. Although this will initially provide good pressure this will significantly reduce as water level lowers.

Yes, Watersmart can provide this service for you! Although a competent home handy-person with the right tools can do this.
