Stock tanks allow the farmer or rancher to provide water to their livestock where water isn't found naturally. Stock tanks come in constructed in ether galvanized metal or polyethylene. Galvanized metal stock tanks are corrosion resistant and tough enough to last for years. Polyethylene stock tanks are corrosion resistant and light weight (when empty) for easy relocation. See our full line of water pumps for transfering water from portable tanks to your stock tank. Never worry about your livestock going without water with Bottomless Metal Stock Tanks. Water flowing into the bottomless stock tank from a windmill or solar powered pump allows fresh water to be replenished continuously.
