Providing government agencies and water-science specialists access to continuous data on key water-quality parameters<\/p>\n

<\/em>A custom-designed Internet of Things (IoT) LoRaWAN\u00ae-based solution deployed in Mauritius is providing government agencies and water-science specialists access to continuous data on key water-quality parameters.<\/p>\n

The monitoring system, a proof of concept retained as part of the government-funded Blue Resilience innovation program, was designed and installed by Digital Twin Services<\/strong><\/a> (DTS), a Mauritian technology solutions provider specialized in Industry 4.0 solutions.  DTS is integrating products from two French IoT companies, Aqualabo<\/strong><\/a> \u2013 a designer, manufacturer, and supplier of a wide range of water analysis and testing devices and instruments \u2013 and Kerlink<\/strong><\/a> (AKLK \u2013 FR0013156007) \u2013 a specialist in solutions dedicated to the Internet of Things (IoT).<\/p>\n

On July 25, 2020, a Japanese bulk carrier called MW Wakashio ran aground on a coral reef southeast of Mauritius, near Pointe d’Esny, a wildlife sanctuary in the India Ocean. It released more than 1,000 tons of fuel oil into the crystal-clear waters of the island, and formed an oil spill on the coast of the archipelago.<\/p>\n

The spill caused the worst maritime pollution in the history of Mauritius, which depends heavily on its waters for its food security and ecotourism. Moreover, it is an area that has some of the most beautiful coral reefs in the world. The southeast coast of Mauritius includes Pointe d\u2019Esny, rich in mangroves, and Blue Bay, known for its coral reefs and classified under the Ramsar Convention on Wetlands. Following the spill, the government launched the Blue Resilience program, which was a call for innovative proposals to better equip Mauritian authorities to manage the island\u2019s \u201cBlue Economy\u201d and its resources.<\/p>\n

The success of this proof-of-concept laid the foundation for setting up an island-wide, IoT real-time online monitoring system for seawater quality, as described in the Mauritian government\u2019s request for proposals issued in February 2022. The project includes the appointment of a consulting firm to guide authorities on the establishment of an IoT-based Lagoon Water Quality Index (LWQI). This will, in turn, promote the maintenance and management of beaches to support the local economy through increasing tourism and related business activities. It also will provide officials with a continuous outlook on the quality of beaches by ranking beach water quality as \u201cexcellent\u201d, \u201cgood\u201d, \u201cfair\u201d or \u201cbad\u201d.<\/p>\n

The first site of the pilot project was installed in October 2021 in Pointe aux Feuilles on the east coast of the island, and a second pilot site is expected to be deployed in the coming months in Albion on the west coast.<\/p>\n

The pilot monitoring installation uses several stand-alone communicating modules from Aqualabo’s AquaMod range, digital sensors consisting of a stand-alone LoRaWAN\u00ae wireless waterproof module and an antenna, such as:<\/p>\n
