Why do some of the tanks need a sand or concrete base?
They are required under several circumstances. The Snyder and RMI tanks require a sand base because the material is thinner than those of the Bushman models. The weight of a full tank of water could cause a puncture in the bottom of the tank if it is placed over a sharp piece of gravel. Also, compacting the sand before placement of the tank ensures that the sand base is stable enough to support the weight of the tank evenly. The very large (3,000 & 5,000 gallon) steel tanks are actually circular bottomless shells with rubber liners; so they require a sand base for the same reason as the Snyder and RMI tanks. The steel Slimline models require a concrete base because their weight is concentrated in their elliptical bottoms, and the edge would cut through soil and perhaps become unlevel. The Bushman models are very durable, and can be placed on any level surface. However, if the Slimline models are placed below grade for any reason, such as to conform to HOA height requirements, we recomm
