Plastic tanks with a narrow footprint for rainwater harvesting or water storage applications where space is limited. Each slim line tank offers excellent impact resistance and are designed with molded in baffles. Like Vertical tanks, these are molded from polyethylene with UV stabilizers. This additive protects the tank from sun degradation, so it can be kept in a yard or elsewhere without worry. All tanks are equipped with a vented Manway and have Bulkheads installed at the bottom and top for your inlet/outlet. Manway and Bulkhead sizes vary from tank to tank, depending on gallon size.
