You are here: Home > Holding Tanks for Sewage & Water > Rectangle Sewage & Water Tanks
Sewage holding tanks and water storage tanks are originally blank. The configuration of the tank, fitting placement and their sizes are up to you. Basic Spin-Weld fittings are included in the price of the tank. Though fittings over 3" and Diptube's (discharge) are extra.

Click Here to download or print a Blank Tank Diagram to customize your tank.

If you find a tank that works for you, feel free to fax or email a diagram with where you would like your fittings and we'll start on your order. All tanks require a 50% deposit at the time of placing the order and generally take approximately 2-3 weeks to ship.

The dimensions are indicated in inches and are calculated as exactly as possible. However, due to the nature of the Roto-Molding process and the physical properties of plastic, a slight swelling and shrinking may occur. Please keep this in mind if your project demands close tolerances.

Holding Tanks Are Exempt From Any Free Shipping Promotions.
