ENVIRONMENTAL AWARENESS & PRESERVAT ION 06 Sect ion 38 Ranhi ll Ut i l i t i es Berhad PRS System, Air Stripper and Gas Scrubber with Treatment Capacity up to 500ppm of ammoniacal nitrogen content ENV I RONMENTAL Awareness & PRESERVAT ION COSTS ASSOCIATEDWITHWATER POLLUTION Cases of pollution typically necessitate WTPs to be shutdown to prevent contaminated water getting to the water supply system and subsequently to consumers. The shutdown of WTPs leads to reduced water being supplied and therefore, affects revenue. The revenue loss incurred corresponds to the duration of the shutdown, which can stretch from onehour to several days. Beyond revenue losses to Ranhill SAJ, consumers also suffer losses, especially industrial and commercial customers. Disrupted water supply may affect business operations leading to commercial losses. Residential customers would suffer various inconveniences when there are water disruptions. Access to clean water is a basic human right which Ranhill SAJ adheres to, so alternative measures to supply water to affected customers are implemented. These include supplying water via tankers to affected areas. This leads to increased operating costs as well as GHG emissions attributed to increased diesel consumption by tankers. Other risks associated with water supply disruption include the build-up of air locks within the piping system. This can potentially lead to higher maintenance outlay as well as increased water loss due to burst or leaky pipes. Frequent shutdowns would also affect Ranhill SAJ’s brand credibility as a reliable water operator. ADDRESSING AND PREVENTING WATER POLLUTION Ranhill SAJ as a private water operator only starts at the intake; that is ensuring the quality of raw water supplied to domestic and non-domestic customers. The responsibility of ensuring the quality and quantity of river water supply rests with other stakeholders within the ecosystem. However, Ranhill SAJ at the cost of RM7 million has deployed a PRS at the Simpang Renggam WTP to reduce ammonia levels to below 10 part per million (“ppm”). In addition Ranhill SAJ’s Environmental Crime Prevention Unit or UCJAS continues to work closely with enforcement authorities. They include Badan Kawalselia Air Johor (“BAKAJ”), the Department of Environment (“DOE”), Ministry of Health (“MOH”), SPAN and the Royal Malaysian Police (“PDRM”). Through UCJAS, Ranhill SAJ has been effective in quickly identifying pollution incidents and reporting these to the authorities. The use of technology i.e. remotely operated drones and such have enabled increasingly effective evidence gathering, which has enabled legal action to be taken against perpetrators. Enforcement aside, Ranhill SAJ continues to undertake awareness and education activities, especially to business premises or villages situated adjacent to rivers. This is part of the preventive approach towards addressing river pollution.
