Potable water submarine pipeline in “greater Male region”

Overview

Male’ Water and Sewerage Company Pvt. Ltd (MWSC) provides drinking water to Male’ City, Capital of Maldives (having a population of around 150,000) together with Villimale and Hulhumale’. Collectively these three islands are referred to as Greater Male’ (aggregate present population is estimated at about 175,000).

The islands are in close vicinity of each other and are separated by narrow but deep sea channels. Each of these islands presently has independent water production and distribution facilities. While the demand in Male’ and Villimale have reached its designed capacities there is no space to add on new storage facilities or production facilities in these locations. MWSC is also providing water services in K. Thilafushi and K. Gulhifalhu. Together with these two island the Area is referred as “GREATER MALE’ REGION”.
