Portable Waste Tanks

Large ablution block but no sewer connection? The Temporary Waste Tank is the hygienic, long-lasting solution.

The Portable Waste Tanks is an engineering-certified effluent tank, designed to sit underneath large ablution blocks – particularly on large construction sites without a sewer connection (or perhaps a special event or an army camp).

A sturdy, durable, rust-construction, the 6000L Mobile Waste Tank is engineered from rigid polyethylene surrounded by a heavy-duty steel frame, and it’s rated to support a building mass of up to 7000kg plus 12 persons.

Available in three different sizes (2000L, 4000L & 6000L), the Portable Waste Tanks are suited to ablution block buildings up to approximately 6m long and 2.4m wide. The 2000L is available in a frame and without a frame.
