WATER CONSERVATION AND MANAGEMENT STRATEGY
In water-scarce Singapore where CDL’s headquarter is located, water supply to the company’s core activities is especially vital as our operations are water-intensive and highly dependent on an effective and reliable supply of water. As a small and efficient nation, the collection, production, distribution and reclamation efforts of water in Singapore are consolidated by PUB, Singapore’s national water agency. PUB’s Four National Taps strategy has created a robust and diversified water supply that has continued to serve the nation since 2005. Approximately 30% of Singapore’s water demand is currently met by water from local catchment areas and imported water; while NEWater and desalinated water make up the remaining 40% and 30% respectively1. CDL takes a holistic approach towards water management to maintain and enhance the efficiency, resilience, desirability and long-term value of our assets and developments. Responsible water management practices also allow us to deliver value to our homeowners and tenants through water and cost savings.

Lifecycle Approach of Water Management
As part of its robust water management strategy, CDL focuses on effective management of water quality and usage across every project’s development and management lifecycle. For instance, CDL’s recently launched Piermont Grand EC, a BCA Green Mark Platinum and Universal Design Mark GoldPLUS awarded development, features a smart energy and water monitoring system that uses an advanced water leak detection algorithm to track and manage power and water usage in common areas more efficiently. Such features at Piermont Grand enable potential water usage savings of approximately 73,881 m3 annually
Water Reduction Initiatives
In addition to incorporating water-efficient fixtures and fittings (e.g. flow regulators, self-closing taps) holistically to maximise water efficiency, CDL annually performs an impact analysis on its utility bills to better understand the implications of higher water tariffs. Monthly water consumption for our key business processes are also closely tracked to ensure we are adequately prepared to continue managing our water usage effectively. Furthermore, the company uses NEWater wherever possible for operations that do not require potable water in order to reduce reliance on potable water.
LIFECYCLE APPROACH TO WATER MANAGEMENT
|Stage in Project Lifecycle||KEY WATER MANAGEMENT INITIATIVES||Benefits|
|Design||Incorporating water-efficient fittings and fixtures||Reduce water usage|
|Using recycled water and drought-resistant plants|
|Construction||Installing self-closing taps|
|Collecting rainwater for washing vehicles|
|Installing water recycling systems for site cleaning|
|Installing silty water treatment system||Prevent silty water from being discharged into water systems|
|Operation of Assets||Conducting routine checks on pipes, taps, urinal and WC flush systems||Prevent water wastage due to leaks or over sensitive sensors|
|Holistic incorporation of water-efficient fixtures and fittings, e.g. flow regulators, self-closing taps||Reduce water usage|
|Using NEWater for operations that do not require potable water||Reduce reliance on potable water|
To date, 12 of CDL’s buildings have been certified as ‘Water Efficient Buildings’ by PUB for outstanding efforts in water conservation. Recognising that water conservation is a shared responsibility, CDL engages our customers through initiatives such as the CDL Green Lease Partnership Programme and Green Living Guide to promote good water conservation practices that complement CDL’s water-efficient design and features incorporated into our buildings.
In recognition of our significant contribution to Singapore’s water security and sustainability efforts, CDL was one of the first recipients of the inaugural Watermark Award by PUB in 2007. Since the inception of PUB’s Active, Beautiful, and Clean (ABC) Waters certification in 2010, CDL has also been a pioneer winner for several of our developments. Our H2O Residences was the first private development to be ABC Waters-certified due to its seamless integration with surrounding water bodies and park.
Key Water Conservation Initiatives in 2019
|Use of recycled water for construction site activities||Property Development||90,010 m3 equivalent to almost $250,000# in savings.|
|Use of NEWater instead of potable water||Asset Management||Use of 87,140m3 of NEWater, equivalent to almost 22% of the total water used and more than $35,700# saved as compared to using potable water|
|#||Water tariffs at $2.74 per m3 before GST, inclusive of water tariff, water conservation tax and waterborne fee. NEWater tariffs of $2.33 per m3 before GST, inclusive of NEWater tariff and waterborne fee. Source: www.pub.gov.sg|
Water Efficiency and Reduction Performance
Recognising that holistic water management maintains and enhances the efficiency, resilience, desirability and long-term value of our assets and developments, we have continuously implemented water conservation initiatives and tracked our water performance. CDL achieved the 2019 CDP A List for water security, an affirmation of CDL’s robust water management strategy.
We regularly review the water management plans for all our properties and introduce initiatives where areas for improvement are identified. For instance, plans are underway to upgrade to the latest water efficient toilet fixtures and fittings at City Square Mall.
In 2019, there was an increase in water intensity for our managed buildings compared to 2018 due to recent changes of the company’s asset management portfolio and tenant mix in a few properties, such as Republic Plaza that saw an increased provision in toilet facilities. In view of the recent changes to our asset management portfolio and tenant mix, we have reviewed and refined our 2030 and interim targets. We commit to reduce water use intensity by 50% from 2007 levels for office and industrial buildings, and 9% from base-year levels for retail buildings by 2030. Performance against these targets will be tracked closely and subsequently reported.
