KLANG: Non-revenue water (NRW) is a big problem for state water concessionaire company Pengurusan Air Selangor Sdn Bhd (Air Selangor).
To counter the problem, the company has embarked on a programme to replace some 716km of old damaged pipes at a cost of RM671.7mil.
Air Selangor chief executive officer Suhaimi Kamaralzaman (pic) said the company had over the last four years replaced the asbestos cement pipes that had been laid out 30 to 40 years ago with new pipes.
He added the bulk of Air Selangor investment had gone towards replacing these old pipes.
“The amount of NRW in 2016 was 33% and we have now brought it down to 29.7% and it is for the first time ever we have managed to reduce it under 30% at the end of 2019.
“That is the fruit of our labour in terms of investment we put in for pipe replacement,’’ said Suhaimi when met recently.
He added that Air Selangor targeted to reduce NRW to 25% by 2025.
“So we are at 29.7% now and it is five years away and if we do it at one percent a year, we can reach 25% at the end of 2025,’’ said Suhaimi.
According to Suhaimi, Air Selangor has also invested in refurbishment and upgrading of water treatment plants and reservoirs.
Air Selangor had invested a total sum of RM1.8bil in capital expenditure from 2016 right up to August 2020.
The RM1.8bil had gone into three main areas of investment, said Suhaimi.
“Out of the amount RM671.7mil went towards pipe replacements, RM194.5mil was for the refurbishment and upgrading of water treatment plants and RM313.1mil was used to upgrade the water distribution system which involved the various pipes and valves,’’ added Suhaimi.
