1. A young farmer of Senegal has an agricultural land on which for 5 years, it has cultivated agronomy with a less production of with a lack of water. It’s informed that a process “Pit Biological” lyseconcept purifies in a biological way domestic waste waters by providing a water of watering fertilizing and enriching for the vegetable hiding. He gets in touch with the company lyseconcept because the process answers all these search criteria to conclude its project. Elements are already in place: An agricultural farm, a farmer trained with the already collected agronomic culture several times, heat, domestic waste waters. It misses only the process to recycle these waste waters. Configuration Its exploitation is in rural environment. It is surrounded by 100 strewn dwellings rather close to its project. Each house is equipped with a tight pit of a volume of 1 m3 to see 1,5m3 which stores the waste water effluent and which must be drained once filled to the brim. These pits are drained per period at the time of an operation carried out by the administration. When the pit is full, in front of the requirement and without means of draining, the user empties it in front of his door. The waste water Lyseconcept develops a system of treatment of purification biological of waste waters per biological micro process. The waste waters concerned with the project, are waste waters different from waste waters of Europe. The biological parameters of the places of the project are identical certain are simply higher such as for example the temperature. The proportion “of drinking water” in waste waters is on the contrary very low. The process is adapted by taking account of this difference. For example: in rural configuration in France with the current effluents the process is regulated for a time of transit evaluated between 12 and 15 days. The temperature can make it possible to reduce this time of transit. Complementary The waste waters found in these tight pits cannot be used in the state. The farmer obtained a contract with the control of the water of Senegal. This drinking water supply will have two advantages for the project. From with dimensions it will dilute the concentrated natural pollution of this kind of waste waters, other it will increase the quantity of water recycled for watering. The quantity of waste waters available of the close tight pits is of 125 000 liters renewable with profusion. The procurement agreement of drinking water of the SDE is 10 000 liters of water, the unit which can give a possibility of watering of 1500 liters per easy day. It is necessary to take account of wintry times when watering will continue but just for the fertilization of the topsoil.
