wants to make sure the canal is not only clean, but also safe for travel.
It hopes to make it one of Bangkok's beautiful tourist attractions by the end of 2017.
The clean-up plan targets the canal in the Bangkok suburban districts of Min Buri and Nong Chok.
Meanwhile, the Biochemical Oxygen Demand (BOD) – dissolved oxygen used by water organisms to break down organic material – must not exceed 2 mg/l, the source said, adding the current BOD level is 7.85 mg/l.
As for the canal section from Pratunam to Min Buri, the DO level must be at least 2 mg/l and the BOD level must not exceed 4 mg/l, the source said. The current BOD level in this section is 9.17 mg/l.
