Drainage Record Plans
The three divisions, namely Hong Kong & Islands, Mainland South and Mainland North, of the Operation and Maintenance Branch maintain the record of existing public sewerage and stormwater drainage systems in the Territory. These drainage records are to be updated continuously according to the as-built drawings of drainage infrastructures. However, it should be noted that the alignments and levels of drains shown on records are subject to verification on site and it is not guaranteed that all the drains have been included in the drainage record plans.
