A transfer of technology from an existing mechanical chlorination system produced in Europe will be done in Madagascar where a prototype will be constructed and installed in Ambohibary on a new piped water system to supply water to 5000 habitants until 8000 habitants at the end of project.

The main goal is the transfer of technology from Europe to Madagascar for the production of mechanical chlorination system with local materials. The prototype will ensure safe water supply of 8000 people through a piped water gravity system to Ambohibary village. The results of follow up of the prototype will establish the bases of a local standard production of a mechanical chlorination system in Madagascar. Gret through the reinforcement of capacities of local companies on the design and on the adoption of standards of construction of piped water gravity system will promote the dissemination of mechanical chlorination systems.

Gret in consultation with local partners and authorities (commune) will put in place a water management approach built on the recovering cost of the water produced, including maintenance, provision for repairs and return cost of investment. This sustainable mechanism will be based on the payment of water by the community , private and commercial client. The capacities of each level of actors involved in this process will be reinforced in order to ensure the sustainability of their own water resource and infrastructures.
After the testing phase of mechanical chlorination system the production could be handled by a workshop which will then be contracted out by Gret to supply chlorination system to be installed on the new piped water gravity systems of Médéa project. Benefits of this approach are a reduction in cost by establishing a local supplier promoted by the standard approach of design spread by Gret to companies involved in the construction of water gravity system.
