Macao Water is the very first contract of Suez Environnement operating outside the European continent in the 80’s. In the early 80’s, there was no medium or long term investment plan to improve the overall infrastructure including treatment facilities, distribution network and automation equipment. The consequences werea lack of pressure in the distribution network due to aged pipeline and high physical leaks. The water quality was considered non-potable with high turbidity. Poor customer service led to dissatisfaction by customers and the government. The project objective was to supply high quality water and provide excellent services to customers
Sino-French Holdings (Hong Kong) Limited, a joint venture which was formed by Lyonnaise des Eaux and Chow Tai Fook Enterprises Limited, too over of Macao Water in June 1985 with 85% of equity. In the same year, a 25-year water supply contract was also signed with the Macau Government.
1/ Reducing leakage and water losses
The company made a comprehensive plan to reduce the Non-Revenue Water (NRW), which was more than 20% before takeover. Losses were mainly from physical leakage caused by the corrosion of underground pipelines, uneven ground settlement in the reclaimed areas, and commercial losses from under-metering. The NRW today has been reduced to 10,2% which is close to the optimum level.
