BMA Drainage and Sewerage Department chief Kangwan Deesuwan said yesterday that after city officials improved the quality of water in Klong Phadung Krung Kasem to a satisfactory level, they came up with the next project to clean major canals – starting with the 40km-long Klong Saen Saeb.
“To recover the water quality, we will add some air into the water plus a bacteria-trapping substance, which will tackle contaminating substances in order to make the water clear and yield no foul smell. The project will be three months long,” Kangwan said.
He said they would start cleaning water in Klong Saen Saeb’s connecting canals – Jan and Bang Tei, which directly receive wastewater from the city. After that, the project would expand to other major canals such as Klong Lat Phrao, Klong Premprachakorn, Klong Bang Khen, Klong Sam Wa, Klong Lat Buakaeo, Klong Phraya Ratchamontri, Klong Bang Sue, Klong Prawet Buri Rom and Klong Phra Kanong.
BMA deputy permanent secretary Adisak Khantee said the city Drainage and Sewerage Department also had a plan to clean and dredge minor canals four times a year. He asked people not to litter in canals and install a grease trap at their homes before draining wastewater into canals.
