stormwater drainage tunnel systems are recommended by the DMP consultants to divert excess rain water from upland areas for discharge directly into the sea. By employing this method, less rain water would enter the existing drainage systems in the urban areas and therefore, the flood protection standard of the areas could be improved with much less requirement for the construction of conventional drainage works.
