Ho Chung River flows alongside Ho Chung Road and discharges to Hebe Haven. Owing to the rapid developments in Sai Kung, the surface runoff had increased significantly and the original Ho Chung River could not meet the flood protection standards. The DSD had based on the recommendations in the Drainage Master Plan and carried out improvement works in Ho Chung River to improve its drainage capacity and alleviate the flooding risks in the nearby areas. The project started in 2007 and was completed in 2009. The DSD had widened the river channel by setting back the southern river bank to relieve flood risks. In addition, new ecological conservation features were introduced to enrich the aquatic and riparian environment and thus enhancing the ecology of the river.
