Case Study


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.

Continuous Water Supply since 2011

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.
