Studies for drainage master plan were carried out on the basis of eight major catchment areas below:
(a) Yuen Long, Kam Tin, Ngau Tam Mei and Tin Shui Wai

(b) Northern Hong Kong Island

(c) Tsuen Wan, Kwai Chung and Tsing Yi

(d) Tuen Mun and Sham Tseng

(e) Northern New Territories 

(f) Sha Tin and Tai Po 

(g) Sai Kung, East Kowloon and Southern Lantau

(h) Southern Hong Kong Island

In addition to DMP Studies, drainage studies were also carried out to cover the following 3 catchments:
(i) West Kowloon

(j) Tseung Kwan O

(k) Ngong Ping 

During 1994 to 2010, we completed Drainage Master Plan (DMP) studies for all of the eight catchment areas and drainage studies for 3 catchment areas above, to provide comprehensive solutions to the flooding problems in individual areas.  These studies comprehensively examined the adequacy of the existing drainage systems and recommended short to long-term drainage improvement measures to meet the required flood protection standards and future development needs.  The studies took into account technical constraints, cost effectiveness and environmental consideration in formulating sustainable short-term and long-term improvement measures.
