JOHOR BARU: Malaysia’s second most polluted river, Sungai Segget, will be rejuvenated within a year following the opening of a RM120mil centralised sewerage treatment plant (CSTP) here.
Iskandar Regional Development Authority (Irda) Projects and Programme Management Office head Mohd Zam Mustaman said that the CSTP was also the first vertical sewerage treatment plant in the country.
“We are very happy that the CSTP is now fully operational after going through three months of observation and testing period.

“It is about 45m high and is able to process more than 33,000 cubic metres of untreated water or equivalent to 14 Olympic-size swimming pool per day. We are currently taking in 10 percent of the total amount,” he added.
Mohd Zam pointed out that the CSTP was able to collect an average of five tonnes of garbage and seven tonnes of sullage per day while on full capacity.
“The 11-storey treatment plant is able to treat sewage from 150,000 residents living along the 3.6km-long river or around the city centre,” he said, adding that the CSTP was open for 24 hours with a workforce of more than 10 experts running it.
He said this during a media briefing on the CSTP building located along Jalan Susur Tun Abdul Razak here on Wednesday.
Mohd Zam added that the CSTP was constructed under the Sungai Segget Transformation Project where it was able to change its quality from a class IV river to a class IIB river.
A class IV river is classified as the most polluted river while a class IIB river is clean but the water is not safe for consumption.

“The main objective of this project is to clean up the Tebrau Straits.
“The CSTP is able to take in and clean up water from the upstream of Sungai Segget, and once we treat it through several processes, it will be channelled back into the river,” he said.
He also said that it would take between six months and a year for the CSTP to improve the quality of water in Sungai Segget.
Mohd Zam stressed that by improving its water quality, the public would be able to enjoy Sungai Segget that was once the pulse of Johor Baru city centre.
He added that the project was a collaboration programme between Irda and the Johor Baru City Council.
He said they would soon hand over the CSTP to the local authority.
