He said the city planned to build a dam, improve all five bridges along the canal, build a walkway underneath the bridges, improve the drainage system, install a wastewater treatment system to clean the canal water, and restore surrounding houses and buildings in line with the Rattanakosin-era site conservation.

He said the project was expected to begin next year and be completed by the end of the year or early 2018.
