Water

Several of our properties have grey water treatment and recycling systems in place. The system at Oxford House at Taikoo Place collects, treats and reuses pantry wastewater from office tenants for cleaning purposes, at an annual recycling volume of 300m³. Several Chinese Mainland properties including Taikoo Hui, INDIGO, Sino-Ocean Taikoo Li Chengdu and HKRI Taikoo Hui have installed systems to collect and treat wastewater and rainwater for toilet flushing and plant irrigation. One Taikoo Place also has a system that collects rainwater which is then recycled and used to irrigate the gardens and green spaces at Taikoo Square and around One Taikoo Place.

We continued to explore any opportunities to save water this year, whether by upgrading or changing maintenance procedures for our equipment, or through new practices in our daily operations. In addition to running a trial programme where we adjusted the cleaning schedule for cooling towers, this year we also partnered with Tsinghua University to begin a study of how our cooling tower water consumption could be reduced. Using simulations, the study will analyse water-use patterns and generate suggestions for optimal practices in different portfolios. We are also in the early stages of exploring the concept of water neutrality, with a view to properly define the scope as it applies to the Company so we may begin to use it in our operations.

In tandem with the new wireless platform for IAQ monitoring at Cityplaza, we plan to implement water leakage detection sensors into the same platform to reduce the consequences of water leaks and accelerate remedial or rectification action when dealing with leak incidents. Through early detection in key locations such as plant rooms and tenancy areas, we can act quickly to stop and fix water leaks. This part of the system is expected to be ready by Q2 of 2022.
