The distribution network was developed into a quasi-close loop system to allow repairs and maintenance to be performed with minimal disruption to water supply system.
Storage capacity has increased from 17,000 m3 in 1985 to 70,000 m3 in 2000.
To avoid pipe bursts due to excessive pressure caused by hydraulic vibration, water hammer equipment was installed.
These investments resulted in decreased pipe bursts and water leak. The water loss ratio was reduced from nearly 40% in 1982 to just 10% today.
