Responsibility for water quality is assigned to the Department of Industrial Works and the Pollution Control Department.
The Industrial Estate Authority will examine water quality in the section linked to the Bangchan Industrial Estate in Min Buri.
Agencies will have to use biological and chemical treatment to increase oxygen in the water, convince households and industries to stop releasing wastewater and throwing rubbish into the canal, and conduct public education campaigns.
The BMA will use funds from the government and its own coffers, while other agencies will take money from the central budget.
The BMA is in charge of improved water quality at a cost of 3.84 billion baht, creating public understanding for canal conservation (50 million baht) and upgrading the canal jetties (14.5 million baht).
The majority of the budget will be used in the first phase from this year to 2017, and the rest from 2018 to 2020. Other City Hall projects include building a steel-reinforced concrete embankment on the canal and constructing waste water treatment facilities.
