The office manages an area with about 3,000 km of canals. Weeds often grow in the gaps beside canal roads, blocking canals and making them difficult to maintain. The wider land beside the canals is open to farmers for planting, and the growers are responsible for weeding and maintenance. The office is looking for suitable locations to plant daylilies, lemongrass etc. along the river bank to save on weeding costs and beautify the environment.
