Excrement is a product of both human and animal life. It is called various words - faeces, excrement, faecal matter, dung, poo and dirt. One popular vulgar expression is the word: 'shit'. Animals don't seem to find excrement repulsive; it is also very profitable to nature. Because this “shit” is a very good fertiliser since it contains a lot of nitrogen.. However human beings find it abominable and moreover know, that it is a big hazard to their health. So they want to get rid of it as quickly and effectively as possible.This aversion to excrement led to the invention of sewage systems in most civilized human settlements today: Where a sewage system cannot be provided, its funcion is supplied by gully-suckers. And this page is just about these vehicles. You can find here a couple of photos of all the common faecal tank cleaners:
A fecal tank cleaner works as follows:
The vehicle stands as close as possible to a cesspool and the crew hauls a hose-pipe down, manually or - on newer vehicles - by a crane - into a faecal tank. Then a pump is turned on. The pump is powered directly from the carīs engine (if based on car body) or by the cardan shaft of a tractor (if based on trailer) or by a separate engine. The pump sucks the air out off the cistern and the waste starts to flow in. filling of the cistern can be checked through a sight glass on the rear side. When the cistern is full, suction is stopped automatically by a level-guard to protect the pump from sucking in liquid - which will destroy the pump. When the cesspool is empty, the hose-pipe is pulled out and the gully-sucker under ideal conditions drives to the nearest field. The crew opens the drain pipe at the rear and the content of the cistern starts to spray out liquid manure to the farmland through a spout. Some vehicles are equipped with a special sprayer for uniform diffusion of such fertilizer. Then cereals or other crops are planted into the ground and in the end, we are all provided with superior production of food crops.
