A master plan for the development of water resources has been completed. It not only acts as a roadmap for the integration and management of water resources in Mauritius, but also as an investment plan for the establishment of infrastructure for water supply.

The Master Plan was prepared by consultants Niras A / S of Denmark and their partner Mauritian Mega Design Consultants Ltd, to meet the national demand for water and to expand the availability of this resource over the long term. In parallel, the plan avoids fragmented decision-making by providing a comprehensive approach to the future development of water resources in the country.

The plan offers opportunities for water extraction across the country where a large share of production could be generated by the development of three new dams, Constance, and Calebasses My Vallon. These dams will be added to the other two projects Bagatelle and Rivière-des-eels which mobilized some 50 million m3 per year.

Thus, the plan calls for the expansion of existing dams, water extraction from rivers, construction of 52 additional drilling and reuse of wastewater for irrigation.

In addition, a part of the Master Plan was devoted to a program of reform of water rights. In this context, the legal framework governing the water sector should be reviewed and new legislation has been recommended.

They also identified infrastructure options for increased mobilization of water resources in the short, medium and long term.
