This would be close to the same stretch of Sungei Kallang along Bishan Park that has been affected by a sewage leak. We have come a long way where it comes to preventing pollution of our waterways, but much more needs to be done to enforce laws and regulate activities that lead to discharge and runoff into the drains and rivers that ultimately feed our reservoirs.
