One example of such a pump is The Gulper. This is a simple hand pump used to empty wet pit latrines and drain interceptor tanks. It consists of PVC pipes for the body, and stainless steel valves and puller rod. The Gulper is lowered into the pit with a footrest at ground-level. The operator raises and lowers a puller rod, which pushes the sludge from the pit up through a pipe into a bucket or bag. Using the gulper, operators no longer need to climb into the pits and come in contact with the septic sludge. It is also much less time consuming as it removes around 3 litres of sludge per stroke. It is a cheaper method of improving sanitation, than trying to replace the pits by proper latrines.
