WATER REDUCTION STRATEGY AND PERFORMANCE
Managing our water supply is critical as our core activities are water-intensive and highly dependent on a reliable supply of water. The Company adopts a holistic approach in maintaining and enhancing the efficiency, resilience, desirability and value of our assets with sound water management practices. This allows us to deliver a reliable supply of water and cost savings to our homeowners and tenants.
Within our managed buildings, the Company draws both potable and NEWater (for non-potable use) from PUB’s utility network, for building operations and maintenance activities. For commercial buildings, water is utilised for cooling towers, toilets, pantries, water features, irrigation and washing activities. At our construction sites, potable water is used mostly by our contractors for sanitation purposes.
| Note: | |
| • | All potable water withdrawal comes from a single third-party water source supplied by PUB. The breakdown of water sources is based on PUB’s Our Water, Our Future report |
| • | Based on PUB’s Our Water, Our Future report, all potable water and NEWater are categorised as freshwater with Total Dissolved Solids levels of ≤1,000 mg/L |
| • | Based on WRI’s Technical Note on Aqueduct Projected Water Stress Country Rankings, the entire area of Singapore is identified to be of high physical risk. The physical risk tool identifies areas of concern exposed to water risks (e.g. droughts or floods) that may impact short- or long-term water availability. As such, all water withdrawal is from water stress areas |
Water Reduction Initiatives
The Company monitors water consumption on a monthly and annual basis to detect any anomalies in water usage that may require attention and identify buildings that may be heavy water consumers, respectively. To reduce reliance on potable water, the Company uses NEWater from Singapore for our operations, where possible.
To date, 10 out of 11 of the Company’s managed buildings (91% of our buildings) have been certified as “Water-Efficient Buildings” by PUB for outstanding water conservation efforts. Recognising that water conservation is a shared responsibility, the Company engages our tenants and homebuyers through initiatives such as our Green Lease Partnership Programme and Green Living Guide. These initiatives promote good water conservation practices that complement the Company’s water-efficient design and features in our buildings.
Water Efficiency and Reduction Performance
Recognising that holistic water management enhances the long-term value of our assets and developments, we have continuously implemented water conservation initiatives and tracked our water performance since 2007. The Company achieved the 2023 CDP A List for water security, marking the the fifth year of this recognition and an affirmation of our robust water management strategy. To maintain our strong track record, we regularly review the water management plans for all our properties and introduce initiatives where areas for improvement are identified.

| CDL Corporate Office | |
| • | Estimated numbers were used for the Company’s Corporate Office in January to March 2019, due to the installation of water meters in our corporate office, having relocated from City House to Republic Plaza during this period. Water consumption data from April 2019 was taken from installed water meters. Figures for 2019 have been restated to include water consumption from corporate office pantries |
| CDL Managed Buildings | |
| • | Water used refers to potable water only. Industrial grade NEWater is not included in the amount of water used |
| • | Water use figures have been restated to remove corporate office water usage quantities as they are reported separately in this report |
| CDL Construction Sites | |
| • | Water use intensity for on-site dormitories is not included |
| Note: | |
| # | CBM and City Serviced Offices are not represented here as they are tenants within a building and do not have separate meters to track respective water usage within their facilities |
| * | 2022 figures were restated to incorporate water use amount from monthly variable charges from building owner |
