Why is it needed to conduct the feasibility study on relocation of Diamond Hill Fresh Water and Salt Water Service Reservoirs (DHSRs) to caverns?
To support Hong Kong’s sustainable development, the Government actively explores innovative approaches to develop new land resources. One of the possible approaches is rock cavern development. Civil Engineering and Development Department completed a study on “Enhancing Land Supply Strategy - Reclamation outside Victoria Harbour and Rock Cavern Development” in 2013. The study recommended a feasibility study on the relocation of Diamond Hill Fresh Water and Salt Water Service Reservoirs (DHSRs) to caverns, with a view to releasing the existing site (about 3 hectares) for housing and other beneficial uses. Through the feasibility study, we will ascertain the relocation proposal is technically feasible and financially viable.
Why do you propose the hillsides north to Chuk Yuen North Estate as site for relocation of Diamond Hill Fresh Water and Salt Water Service Reservoirs (DHSRs)?
According to the study on “Enhancing Land Supply Strategy - Reclamation outside Victoria Harbour and Rock Cavern Development” completed by the Civil Engineering and Development Department in 2013, the preliminarily proposed site for relocation of DHSRs to caverns was the hillsides north to Chuk Yuen North Estate.
After review, the Consultant confirmed the hillsides north to Chuk Yuen North Estate is the most suitable site for relocation of DHSRs. In summary, this area has the following favourable conditions.
The geology of the proposed relocation site, belonging to hard granite with no obvious weak zones and faults, is most suitable for construction of large caverns;
The majority of the area belongs to government land; and
With appropriate measures, the traffic impact arising from the construction and operation stages of relocation of DHRSs could be minimized.
Will the relocation proposal cause any adverse impact to the surrounding environment?
The Consultant carried out the preliminary assessment on the environmental impacts due to the relocation project during the construction and operation stages, which include air quality, noise, water quality, ecology, waste management and visual impact, etc. The Consultant also proposed suitable mitigation measures, to ensure the compliance with the requirements of the relevant standards.
