Project General Description

The Mahé Sustainable Water Augmentation Project (MSWAP) is identified in the Medium Term National Development Strategy (MTNDS) for Seychelles, as one of the flagship projects targeted at attaining the country’s development goals. The project seeks to fulfil the country’s targets as set out in the Seychelles Water Development Plan 2008 – 2030 (SWDP) supported by the African Water Facility (AWF). One of the proposals put forward in the SWDP was the development of a new water system, comprising of raising the height of the La Gogue Dam reservoir to increase the storage capacity; construction of a new water treatment plant downstream of the dam; and construction of distribution mains and connections to existing pipelines where appropriate. Indeed, the existing distribution systems which supply the northern parts of Mahé are overstretched, since the supply areas are quite remote from the two main water treatment plants. Many of the existing pipelines are old, under-sized leading to leakages and limiting the supply of water to already connected areas. The main benefit of the project will be the improvement in quality of life and reliability of water services for household, industrial, commercial activities and tourism, especially in the dry seasons. Its total cost is estimated at USD 26 million, net of taxes and duties.

Project Objectives

The objective of the project is to contribute to economic development through improving water supply capacity and resilience to climate variability and change. This particular intervention will strengthen the foundation of economic growth by providing reliable and affordable water supply, which is critical in supporting tourism, the main employer and economic driver, and other manufacturing sectors (fishing and beverages).


Direct beneficiaries of the project are the water users on the island of Mahé whose demand is projected to increase by 130% by 2030. Domestic, industrial and touristic use, which currently accounts for 36%, 11 % and 5% of the total water demand, are expected to increase by 140%, 400% and 190% respectively.
