Flood Prevention > Ecological Enhancement > Greening of Existing Channels

Apart from environmentally friendly designs in flood control projects, we also apply the same concept to redress some existing nullahs in the rural and urban areas.  Aged concrete slopes or granite parapets alongside open channels are being replaced by hydromulch, grasscrete and/or planters.  Examples of our effort can be seen at nullahs in Kai Tak, Jordan Valley and Tsui Ping.
