Buy Double Mains Toilet Waste Tank
Operating a double mains toilet block on a job site or venue without direct access to main sewer drainage? At shippinngcontainer4all.com, our Double Mains Toilet Waste Tank provides an instant, fully enclosed waste containment solution engineered to sit directly underneath or alongside your 2-cubicle portable washroom.
Fabricated from heavy-gauge welded steel, this low-profile effluent tank is specifically sized to support the footprint of standard double mains toilet containers. By mounting your toilet cabin directly on top of the tank, gravity handles waste disposal seamlessly without requiring external pumps.
Featuring multiple large-diameter waste inlet points, sealed emptying ports for vacuum tanker servicing, and visual level indicators, this heavy-duty holding tank ensures clean, leak-proof, and odor-controlled operation on remote construction sites, greenfield event locations, and temporary industrial yards.
