Water & Waste Holding Tanks
These holding tanks can be used with mobile office trailers at construction sites or on-site at special events or festivals. These septic tank services are also incredibly useful for industrial turnarounds and disaster relief applications.
These strong, impact-resistant polyethylene tanks will provide many years of dependable service. With two internal pillars and thickened corners, On Call’s holding tanks are designed to stack higher, resist cracking, and decrease wear-through from sliding and dragging. Fittings are molded, not spin-welded, for greater strength, and all ports and connectors are recessed to guard against breakage. Also, tanks can be connected end-to-end with standard rubber fittings to increase waste storage when needed.
Many of our Holding Tank Rentals are paired with our signature Pro-Flush Trailer Sanitation System. This system utilizes two portable holding tanks. One tank supplies the fresh running water, while a second tank collects the waste. We also provide scheduled septic service on this system which includes water delivery and waste pumping. Our system eliminates your need to be connected to city water and gives you more mobility on site.
