Plastic tanks offer economical bulk liquid storage for cities and counties. Cheaper than many steel and fiberglass options, polyethylene tanks never rust or corrode. Their construction prevents most leakage and water loss.
Most poly tanks come in one of three types: heavy duty with a 5-year warranty, premium weight with a 3-year warranty, and water-only tanks with a 1-year warranty.
Most plastic polyethylene tanks can be customized with fittings particular to your needs. Bolted, bulkhead, coupling, and spinweld fittings are all options, in addition to valves and strainers.
