To let the public have a better understanding of the water treatment process and enhance their awareness of water conservation, an Open Day was held on 3 December, 2011 at the Ngau Tam Mei Water Teatement Works. Over 1,000 visitors were guided by the department's volunteers for a technical tour to get acquainted with the water treatment process and stringent water quality monitoring process.
