Over a period of time that is almost 20 years, the increase in demand for water has exerted much pressure on the fresh water bodies of the island. This has led to deterioration in the quantity as well as quality of inland fresh waters. Water is made use of for producing electricity and for commercial industrial as well as domestic usage.
In Mauritius, rain is the source of supply for water. The rains occur from December to around April and February as well as March are the most wet months.
What causes water pollution in Mauritius?
The industrial units caused much pollution of waters in the island. About 1100 industrial units are in operation, which are responsible for the water pollutant. The liquid effluents on discharge cause much pollution to the ecosystem. The water quality provided to the consumer comes down. As the island is small in size the effluents can easily affect the waters of the island.
More about marine pollution in Mauritius<.b>
At the Plaine luazun Industrial estate ( this is situated at the entrance of the port Louis), one comes across dye houses, detergent, soap as well as chemical manufacturers, food canning, galvanizing as well as ethanol distilleries among many. These industries make use of 5000m3 of the available water and the effluents are discharged into the sea causing pollution. Such discharges affect the marine ecology, like causing a high rate of death among fishes. The death of fishes could be because of the hot discharge of the effluents.
One can take another example. In the industrial are of Vacoas-Phoneix about 30 industrial houses are there, consisting of 6 dye-houses as well as an edible oil refinery. Water made use of by these set-ups is about 2000m3per day. The liquid effluents are not treated and these are discharged into the local sewerage system, that leads up to the St. Martin treatment plant. There the treatment is only primary in nature,and the effluent gets discharged into sea-waters at Pointe Moyenne. Naturally, the waters get polluted, causing damage to marine ecology.
Many of the sugar mills are also very close to the sea or even the rivers. The liquid waste from these units do not get treated and enter the streams or rivers causing pollution of the waters.
The aquatic life and the fish mortality are issues which are of much concern to the Government of Mauritius.
Mauritius is known for its diving sites. The marine ecology has to be preserved. Pollution of the sea waters has to be controlled in order to ensure that the survival of acquatic life remains intact.
