U-ACT toilets feature one- or double-stance toilets with a lined pit and a brick superstructure. Pit lining prevents groundwater contamination and ensures that a facility can be emptied when it is full (ideally by a vacuum truck). To guarantee ease of access for the hose from the vacuum truck, the pit is equipped with a removable brick. The solid brick and cement structure makes the latrine very durable. All latrines are equipped with wooden doors and a sturdy lock. To reduce flies and odours, the U-ACT latrine is provided with a ventilation pipe. Furthermore, it is equipped with a handwashing facility that can be filled with rainwater or piped water. In locations where there is a risk of flooding and/or a high water table, the latrine is raised.
