Placement of over 110 Majfara and Reef Balls™ units in the Hidd area, on behalf of the Muharraq Sewage Treatment Company (MSTP) and as part of their Corporate Social Responsibility (CSR) Programme. The CSR program started with a learning event held at the premises of Reef Arabia, and where school children from the Al Hedaya Al Khalifia Secondary Boys School and the Hidd Secondary Girls School participated in an environmental workshop. The school children were also part of the post monitoring team, specifically in the preparation of monitoring reports.
