SINGAPORE: A total of 74 civil and building contractors have been penalised so far this year for discharging silty water into the waterways, as well as not providing adequate Earth Control Measures (ECM) at their sites, PUB said on Tuesday (Dec 26).
Silty water is generated when rainwater run-off mixes with exposed earth materials and soil at construction site. Contractors are required to implement measures at their sites to remove silt before the water is discharged into public drains.
"Silt, if not removed from construction discharge, will build up in the waterways," said PUB in its press release. "This will affect waterway's effectiveness in channeling stormwater flow and also the environmental aesthetics."
Huationg Contractor was fined S$13,500 in total for four ECM offences, and Samwoh Corporation had to pay up S$10,500 for three violations.
Two other companies convicted - Peng Chuan Engineering Construction and Stallion Development - carried out works that could lead to the discharge of silty water without obtaining a clearance certificate from PUB. They were made to pay S$7,800 and S$7,000 in fines respectively.
PUB's chief engineer for drainage operations Choy Wai Kwong, said everyone has a part to play in keeping the waterways clean.
"Two-thirds of Singapore is water catchment. Silty discharge into the drains and canals will result in accumulation of sediments and affect drainage capacity," said Mr Choy as quoted in the release.
