ENVIRONMENTAL AWARENESS & PRESERVAT ION Sect ion 06 39 SUSTAINAB I L I TY Report 2022 WATER QUALITY REGULATORY COMPLIANCE (MALAYSIA WATER OPERATIONS) Ranhill continues to implement its Water Safety Plan (“WSP”) which focusses on identifying all hazards that affect the safety and acceptability of drinking water. Risk assessment starts from the catchment areas right through to treatment and distribution and extends to the consumers’ premises. WSP Programme Raw Water Source Awareness Water Treatment Plant Auditing Programme Water Supply System Auditing Water Treatment Plant Intra-laboratory Test WSP Document Review Water Quality Troubleshooting Programme ENV I RONMENTAL Awareness & PRESERVAT ION Ranhill SAJ conducts quarterly raw water quality monitoring based on Raw Water Quality Index set by Department of Environment (DOE). 1. Dissolve Oxygen (DO) 2. Biochemical Oxygen Demand (BOD) 3. Chemical Oxygen Demand (COD) 4. Suspended Solid (SS) 5. pH 6. Ammonia WATER CONSUMPTION In FY2022, water consumption has increased due to increase in non-domestic consumption demand. Opening of the economy, increased industrial and commercial activities, the removal of pandemic related restrictions, has increased water consumption during the financial year. Domestic consumption had decreased as the population, from being largely confined to their homes during the pandemic, transitioned back to their regular work and lifestyle routines. Water consumption data is scoped primarily to Ranhill SAJ , RWT and RPI and RPII.
