Project General Description

The present intervention concerns the Plaines Wilhems Sewerage Project. It’s designed because of the degradation of the coastal waters in the environs of the outfall from the St. Martin Treatment Plant, of the imminent pollution of the groundwater resources of the Plaines Wilhems aquifer and the surface waters of the area as well as the health risks associated with inadequate drainage capacity resulting in overflows. The Plaines Wilhems Sewerage Project consists of the expansion of a sewerage Treatment Plant at St. Martin, construction of a trunk sewer, construction of sewer reticulation systems and house connections and replacement of parts of the freshwater pipe-work system. It should improve the living environment for the people in the project area, contribute towards maintaining the earnings from the tourism industry, and benefit sugar cane-based as well as other farmers by providing treated effluent for irrigation water and compost for soil conditioning. The components of the project are: (a) construction of 41 km of sewers in diameters ranging form 200 mm to 600 mm laid to a depth ranging from 1.5 to 5.0 metres; (b) an estimated 823 access manholes at network nodes; (c) some 3,957 house connections and (d) replacement of about 10km of water supply pipes.

Project Objectives

The objective of the project is to provide environmentally appropriate collection and treatment of sewage and disposal of effluent and sludge from the Plaines Wilhems district.

Beneficiaries

The project targets the population of Plaines Wilhems. Both the general population and visitors to Mauritius should benefit through the prevention of water-borne diseases, the protection of economic activity (including tourism), the protection and enhancement of environmental quality, and the conservation of natural resources that will result from the project. Sugar cane farmers in the vicinity of the St Martin Sewage Treatment Plant should also benefit from availability of additional irrigation water from treated and disinfected effluent.
