Mauritius to Boost Water Supply With 5km Pipeline This Weekend

Mauritius is set to begin a significant water infrastructure project this weekend, as the Central Water Authority, known by its French acronym CWA, announces the start of connection works between Tamarind Falls and La Marie, two areas in the western and central parts of the island.

The project involves laying a pipeline stretching approximately five kilometres. Once completed, it is expected to inject an additional 10,000 cubic metres of water per day into the national distribution network, a meaningful boost at a time when water pressure and availability have been under strain across several parts of the island.

The urgency behind the project is partly explained by a sharp decline in output from boreholes in the Hautes Plaines, the highland plateau region in the centre of Mauritius. According to the CWA, borehole flow rates in that area have dropped by around 30 percent, reducing a key source of groundwater that the network has traditionally relied upon.

The Tamarind Falls to La Marie link is designed to compensate for that shortfall by creating a new route through which water can be channelled into the system. By connecting these two points in the network, the authority aims to redistribute supply more effectively and reduce pressure gaps experienced by households and businesses in affected zones.

The CWA has not yet specified how long the works are expected to take or which roads and neighbourhoods may be affected during construction. Residents in the La Marie and surrounding areas, including Quatre Bornes and other parts of the Plaines Wilhems district, may want to monitor official CWA communications for updates on potential disruptions.

What this means: For everyday Mauritians, particularly those in the central and western regions who have experienced irregular water supply, this pipeline could bring more consistent access to water once operational. It is part of a broader challenge facing the island, where ageing infrastructure, population growth and increasingly dry weather patterns are placing greater stress on the freshwater network. The 30 percent decline in borehole output from the Hautes Plaines is a warning sign that groundwater reserves need careful management alongside investment in new distribution links.

The announcement comes against a backdrop of heightened concern about water availability in Mauritius. Reservoir levels have been fluctuating, and recent dry spells have sharpened public focus on how the island manages its water resources heading into the hotter months.
