Also known as a tanked latrine, this works best in high water table or hard ground environments. There have always been make-shift versions fabricated on site using tin or plastic drums framed under a step-up latrine. The container requires pumping out at intervals.
AirCell has long known of interest in this solution and has a design ready for market, called the CCubicle TTanker, based on our existing and successful CCubicle range, but incorporating technology from our water-tank WWashTank unit.
It is a total solution, flatpacked but incorporating a rubber tank, enclosure, steps, handrails, vent pipe and squat or sit-on plate – delivering approx 800 litres of waste storage, sufficient for 12 people for a month.
