Looking for locally adaptable methods of emptying septic tanks in areas where de-sludging infrastructure is still not available. Please share your views.

Paulinho, a small entrepreneur in Maputo, Mozambique, is moving into the pit emptying business. This video shows how it works https://www.youtube.com/watch?v=r578JtJkIyA&feature=youtu.be

French English
La fosse est un réservoir de stockage des excréments. Si ce réservoir doit être vidé c'est bien qu'il n'y a pas de traitement d'élimination ou de réduction des excréments. Le stockage favorise la transformation des excréments en boue d'excréments: un véritable poison pour l'environnement. Cette boue se détruit en temps année par la méthanisation du milieu sous l'action de la putréfaction.
La boue d'excrrément est soit vidangée manuellement sur un paillis de branche, soit dans un trou à coté du réservoir, soit transportée par un camion vers une station d'épuration. La dite station d'épuration qui reproduira en sortie la même quantité de boue que celle entrée.
Constat: En 2015 la population mondiale en est toujours au même stade qu'il y a 5000 ans : la défécation à l'air libre.
Plus de 45 000 millions de tonnes de boue d'excréments sont produits par la population terrestre qui se retrouvent sur le sol dans l'attente d'un hypothétique traitement.
Des milliards sont son t investis en infrastructure de gestion des excréments pour rien. Aberrant quand on sait que dans la nature une matière fécale disparait entre 10/12 jours.
Encore plus quand on sait qu'en Assainissement Biologique, les excréments sont totalement éliminés. La terre est un milieu Aérobie total. il n'existe aucun endroit sur terre ou il n'ya pas d'oxygène et encore moins dans un milieu d'eau puisque la fomrule de l'eau est :H2O.

The pit is a simple storage tank of the excrements which has septic only name. If this tank must be emptied it is although there is no treatment of elimination or reduction of the excrements. Storage supports the transformation of the excrements into mud of excrements: a true poison for the environment. This mud is destroyed in time year under the action of the putrefaction by a strong methanisation which evaporates in the atmosphere.
The mud of excrement either is drained manually on a mulch of branch, or in a hole beside the tank, or transported by a truck towards a sewage treatment plant. The aforementioned sewage treatment plant which will reproduce at exit the same quantity of mud as that entered.
Report: In 2015 the world population is always at the same stage that 5000 years ago: the defecation with the free air.
More than 45,000 million tons of mud of excrements are produced by the terrestrial population which are found on the ground in waiting of a hypothetical treatment.
Billion is its T invested in infrastructure of management of the excrements for nothing. Being wrong when it is known that in nature a fecal matter disappears between 10/12 days.
Still more when one knows that in Biological Cleansing, the excrements are completely eliminated. The ground is a total Aerobic medium. there does not exist any place on ground or there is no oxygen and even less in one medium of water since the formula of water is: H2O.

Hi Saladin; Not sure where you are looking for a solution but traditionally there are only two ways to empty a septic tank: manually or via a vacuum truck. The problem is compounded by the fact that people do not want to manually empty because of the nature of the waste and in some areas social stigmas. That only leaves vacuum trucks which are not always available in rural areas especially the further you get from cities. In case you do manage to find a truck keep an eye on it as I have often found that instead of them taking the sludge to a treatment facility they dump it into a nearby depression or river resulting in pollution entering the environment.

I therefore prefer to avoid the entire family of soak pit and septic tank related solutions and have graduated towards using anaerobic digesters.

Hope this helps...
Sanjay
