ENVIRONMENTAL AWARENESS & PRESERVAT ION Sect ion 06 37 SUSTAINAB I L I TY Report 2022 PRESERVING WATER RESOURCES WATER CONTAMINATION AND POLLUTION The issue of upstream water pollution has significantly decreased over the past three years due to improved stakeholder awareness as well as more stringent and effective regulatory enforcement. Despite the reopening of economic and commercial activity post COVID-19 pandemic, the number of reported pollution cases continues to be on a downtrend. The main cause of pollution is industrial, agriculture and domestic discharge, untreated sewerage as well as effluent and discharge from upstream sand mining activities. Many conventional effluent treatment systems do not adhere to regulatory standards for effluent discharge or are poorly maintained. As a result, discharge into rivers exceeds permissible levels, thus causing river water contamination. Once the level of contaminants exceeds a certain threshold, WTPs must be shut down. Shutting down WTPs is the only option to prevent contaminated water from being distributed through the network and to consumers. However, in FY2022 as mentioned, the number of incidents of pollution continue to decline. TOTAL NO.
