DC-902500 | For convenient and efficient water storage, use Duracast’s 2500 gallon plastic water tanks. These water tanks are manufactured with FDA approved polyethylene resin to ensure safe potable water storage. Due to freight cost considerations the 2,500 gallon tank is usually the most cost effective storage solution when considering the cost per gallon. Common uses for these tanks include: fire sprinkler systems, irrigation, municipal utilities, agriculture, construction, rain harvesting, natural disaster preparation, emergency water supply and well storage. Available colors include white, green and black. When storing water outdoors, use black or green tanks to slow the growth of waterborne algae. White tanks are translucent and allow you to view content levels quickly. These tanks feature a 16-inch vented lid, gallon calibrations and a 2-inch outlet. This is a 1.2 specific gravity tank.
