Enhancement Works for Kwun Tong Sewage Pumping Station

Enhancement works included constructing an underground balancing facility with a storage capacity of 16,000 cubic metres to enhance the effectiveness of sewage treatment. To implement the "single site, multiple use" initiative, the roof floor of the pumping station was developed to a landscaped deck and opened for public use. It joins with the adjacent waterfront area to form the 1.8-hectare Cha Kwo Ling Promenade. A pavilion, landscaped areas, lawns, children's play facilities, fitness equipment and more are available at the promenade. The waterfront area also serves as an Inclusive Park for Pets where the public can bring their pets.

Relocation of Sha Tin Sewage Treatment Works to Caverns

Releasing of about 28 hectare of land after relocating the existing Sha Tin Sewage Treatment Works (STSTW) to caverns brings multifold benefits to the communities of Sha Tin and Ma On Shan Districts as a whole. On one hand, the environment of the existing STSTW site and its surroundings will be greatly improved. Comparing to the existing open-plant arrangement, the odour management of the proposed relocated STSTW in caverns, with caverns as natural barrier, can be efficiently enhanced so as to minimise the odour impact on the surrounding communities. On the other hand, developing the vacated site for residential and other beneficial uses will benefit the community by meeting the public’s needs.
Stage 1 Works including site preparation and access tunnel construction commenced in February 2019 and targeted for completion in 2022 Q4. The remaining construction works will be implemented in stages. The total construction period of the project is estimated to be about 13 years.
