Sustainable Development

The Relocation of the Shatin Sewage Treatment Works

To promote Hong Kong’s sustainable development, the government has been actively developing land resources. The Civil Engineering and Development Department finished the “Enhanced Use of Underground Space in Hong Kong” research in 2011, proving that Hong Kong’s geological conditions are particularly suited for developing caverns. The government later decided on the relocation of the Shatin Sewage Treatment Works to A Kung Kok Nui Po Shan, expecting to free up around 28 hectares of land from the current site for housing and other beneficial uses. CSHK successfully contracted the project of the site development in the relocation of the Shatin Sewage Treatment Works to A Kung Kok Nui Po Shan, as well as the construction of the connection tunnel.

At the moment, we have finished removing planters at the roundabout of A Kung Kok Shan Road, and constructed temporary footpath and cycling track besides Hang Tai Road. Currently, constructions in progress include road construction connecting A Kung Kok Shan Road and ventilation shaft, foundation works for temporary flyover, and site formation works at the Nu Po Shan main connection tunnel entrance.

During our construction, besides from adopting advanced technology to ensure smooth and safe construction, we also adopted greening policies and cared for the community, in order to show our people-oriented spirit. This increases the effectiveness of communication and different aspects of the construction.


We introduced BIM, 4D immersive computer virtual environment and geographic information system technology in this project and uploaded all the information and data obtained to the cloud platform. Utilising this information combined with three-dimensional building models to conduct analysis can effectively assist us in monitoring the progress of the construction.

We also utilised virtual environment and 4D immersive computer virtual environment to simulate different work accidents and provide safety training for workers. This can effectively increase worker’s safety awareness compared to traditional training methods, and prevent dangerous situations from happening.

The construction site adopts solar photovoltaic panels to collect light sources in powering LED lights, replacing traditional street lamps. This can make good use of renewable resources, saving electricity fees and eliminating the need to dig roads for laying wires. This not only reduces the installation time for street lamps, but also effectively reduces the construction cost. Moreover, each electric lamp functions independently, allowing maintenance to be quick and simple.

We are committed to implementing the greening of construction site, greening office roof using grass, and using recycled plastic bottles and old water barriers to grow potted plants, which are placed at construction sites and the hoarding, to further increase environmental awareness of construction site workers.

We deeply understand that major construction in the area will often change the lives of residents. By listening to residents’ opinions and suggestions, it helps us to optimise construction management and ensure construction safety. We actively go into the community to interact and discuss with residents, such as visiting the neighbourhood with volunteers during mid-autumn festival, keeping local district councilor updated on construction progress, conducting group meetings with nearby residents, attending worship service invited by village representatives, and donating face masks and hand sanitisers for nearby villagers during the epidemic outbreak.

In the future, we will continue to build good relations with residents, and communicate with the neighbourhood regarding the construction project, to create a harmonious environment for the society and achieve sustainable construction.

The construction site also adopted different methods to repel snakes, mice and mosquitos, including installation of snake proof fences, using sulphur powder, snake repellant, and setting up solar powered mosquito lamps and rat repeller, to avoid animals entering construction sites and getting hurt and ensure construction site safety.
