Water is a shared resource that we are committed to managing sustainably. Everyone, everywhere has the right to clean, safe water for drinking and sanitation. Responsible water stewardship is a key part of achieving our ambition to strive for zero environmental impact in our operations.
2010 - 2020: reduce water use by 30% per tonne of product in all factories.
- Work to achieve water efficiency and sustainability across our operations.
- Advocate for effective water policies and stewardship.
- Engage with suppliers, especially those in agriculture.
- Raise awareness on water conservation and improve access to water and sanitation across our value chain.
In Sri Lanka
2025: Reduce 5% of our specific water consumption annually in our factory.
2025: Conduct 10,000 awareness programmes on improved water management practices for 10,000 farmers.
Water savings in our factories around the world.
3.7 million m3 in 2018
Direct water withdrawals per tonne of product in all categories.
-29.6% since 2010
In Sri Lanka
We have reduced our water consumption by 30% in our factory operations equivalent to water consumed by 1,200 households per annum (2008 – 2019 per tonne of production)
Improved technologies in UHT line
Our new and improved technologies in our UHT (Ultra Heat Temperature) lines help us reduce the water we use by 33 million litres a year. This is equal to the water used by 223 households a year.
Water recirculation mechanism
We also have a water recirculation mechanism in our Band Dryer vacuum pumps that helps us reduce our use of water and energy significantly.
We strive to ensure that all our new project investments are in line with our objective of minimising water use in our operations.
Wastewater treatment plant
Our wastewater treatment plant treats wastewater generated from food processing. We reuse this water in our factory operations for gardening, toilet flushing, pipe cleaning operations, and water-cooling processes. The water is also used by our neighbouring coconut plant nurseries. The plant reuses 148 million litres of water a year, which is equal to the water used by ~ 988 households annually.
Reverse Osmosis (RO) plant
Our Reverse Osmosis (RO) plant helps us further purify treated wastewater to drinking water and also helps improve the efficiency of our boilers. It reduces our factory’s use of water by 5,571 m3 per year, equivalent to the amount of water 35 households would use over 12 months. It also helps us save 2,946 GJ of energy every year in our operations, which is equal to the amount of electricity 1,100 households would use over 12 months.

Water from fresh milk
We also extract water from fresh milk during our milk powder production process, and use it as boiler feed water for our steam generation process. This enables us to make dual savings every year: energy by 0.3% and water by 4,160 m3 (avg.)
CIean-In-Place (CIP) is a method of cleaning interior surfaces of pipes, process equipment, filters etc. without the need to disassemble them. The water we use during our CIP process at our factory is transferred to storage tanks so that we can reuse it for other purposes within our factory.
We use dry cleaning methods first to clean our factory, before wet cleaning, to increase the quality of used water and make it more conductive for reuse.
We recover 100% of recoverable steam produced during our operations and condense it to be used as boiler feed water. We recycle 47 million litres of water every year, which is the same amount of water used by 310 households a year.
Our rainwater harvesting system was awarded a Green Building Award by the Green Building Council of Sri Lanka. This system helps us transfer the rainwater collected on our factory roofs to harvesting pits. The collected water is then charged into the ground to conserve the water bed. We harvest an average of 850,000 litres of water a year through this initiative.
We monitor the water use in our factory every day and report them at our Daily Operations Review meetings.
