When we met Agbessi, my husband, a plumber, and he, planned to build a familiar size biogas tank in his yard, but it failed due to the lack of money. If I mention this, it is because I think someone can be interested in it. The ideal to the good function of these tanks is a hot climate. We wanted to build a tank of a continous system. This is very useful in those places without drains or septic tanks.
Wastes take two or three years approximately to evacuate.
Because of it, a free of germs or parasites, and ready to use, fertilizer is obtained. Due to this, the problem of filling up and cleaning the tank are solved.
