Vertical corner storage tanks are designed specifically for tight space storage applications. They are ideal for emergency storage needs when available space is limited. Both sizes will fit nicely into a standard size closet. Linear polyethylene tanks are FDA approved for potable water storage. Our tanks come in three standard colors: natural so that you can see the product level, black to reduce light penetration, and grey granite for a more aesthetically pleasing look. Custom fittings and sizes are available upon request (shown with residential emergency drain kit, included in price). Please call today to order! If you have any questions, we would be happy to answer them.
