The State Government of Sabah in conjunction with Jabatan Air Negeri Sabah (JANS) has implemented Non Revenue Water (NRW) Reduction Projects (Phase 1,2,3 and 4) in the Kota Kinabalu water supply district and has achieved outstanding results and reductions. Water Systems Optimisation Sdn Bhd (Malaysia) was appointed as the NRW specialist contractor for the city of Kota Kinabalu from 2010 until 2016.
A large proportion of the investment was used for the implementation of a sophisticated monitoring and maintenance system, which included the implementation of 300 district metered areas (DMAs), the installation of a large number of electronic data loggers, mechanical and electro magnetic flow meters and pressure control valves.
The water supply and distribution network is monitored at a state-of-the-art Data Management Centre utilising the NRWManager Management System. This system integrates all the logged data, GIS and customer billing data for 24/7 monitoring of the NRW levels in all parts of the water supply and distribution network.
