The MAPET and Sludge Pumps require daily maintenance (cleaning, repairing and desinfection). Workers that manually empty latrines should clean and maintain their protective clothing and tools to prevent contact with the sludge. If manual access to the contents of a pit require breaking open the slab, it may be more cost effective to use a Gulper to empty the latrine. The Gulper cannot empty the entire pit and therefore, emptying may be required more frequently (once a year), however, this may be a cheaper alternative than replacing a broken slab.
