Bangkok Metropolitan Administration (BMA) has a goal to develop and improve landscape of Saen Saep Canal with integrated cooperation from various organizations and agencies such as the BMA District Offices and Departments; external organizations such as Pollution Control Department, Department of Industrial Works, and Department of Public Works and Town & Country Planning; as well as private sector and people sector. Campaigns and activities were launched to raise public awareness among people and business establishments located along Saen Saep Canal and its branch canals to stop disposing or discharging waste or sewage into moats and canals and public water bodies. They were also requested for kind cooperation in maintaining the landscape on both sides of the canals to be clean and beautiful in order to create a good landscape and environment under the concept of “Facing the Canal”.
In terms of wastewater treatment in Saen Saep Canal, solutions have been implemented at various sources as follows:
- Pollution generated from household activities accounts for 70% of the amount of wastewater discharged into Saen Saep Canal and its branch canals. Approach for wastewater treatment is to gather wastewater from households into wastewater collection systems of the BMA. At present, the BMA has offered wastewater treatment service implemented by a large water quality control plant to collect and treat wastewater which will cover a whole Saen Seap Canal.
- Pollution generated from buildings and business establishments accounts for 29% of the amount of wastewater discharged into Saen Saep Canal and its branch canals. The BMA has integrated cooperation with Pollution Control Department, Department of Industrial Works, and Department of Public Works and Town & Country Planning to enforce related laws on wastewater treatment so that business establishments have installed standard wastewater treatment system and treated wastewater before discharging into the public water bodies.
- Pollution from boat cruising and accumulation of sediment at canal bed accounts for 1% of the amount of wastewater discharged into Saen Saep Canal and its branch canals. The BMA has dredged and removed sediment in Saen Saep Canal and has plans for preserving and maintaining of canals in Bangkok area every year.
Moreover, the BMA has campaigned for the promotion of public participation from all sectors to join hands in preserving and maintaining the landscape on both sides of the canal to be beautiful and clean. This aims for better landscape and environment of Saen Saep Canal and canal development as a prototype canal of cooperation that bring about sustainability in the future.
