Caring for water

Water is a shared resource that we are committed to managing sustainably. Everyone, everywhere in the world, 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

By 2020: Reduction of 6% of specific water consumption within factory against 2019 actuals (water consumed by 110 households).

By 2020: 9,000 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

Saving water by 30% in our factory operations equivalent to water consumed by 1,200 households per annum (2008 – 2019 Nov per tonne of production)



Improved technologies in UHT line

We have invested on improved technologies in our UHT (Ultra Heat Temperature) lines, to reduce our water consumption by 33 million litres per annum, equivalent to water consumed by 223 households a year.

Water recirculation mechanism

We also have a water recirculation mechanism used in our Band Dryer vacuum pumps that significantly reduces our usage of water. This has enabled us to also reduce our energy consumption by a notable degree.

We strive to ensure that all our new project investments are in line with our objective of minimising our water usage in our operations, enabling greater savings and maximised water conservation.


Wastewater treatment plant

Our water treatment plant treats wastewater generated from food processing. We reuse this water in our factory operations for gardening, toilet flushing, pipe cleaning operations, water cooling processes and coconut cultivation to water neighbouring coconut plant nurseries in the Mahayaya estate. The plant reuses 148 million litres of water equivalent to the water consumed by ~ 988 households per annum.

Reverse Osmosis (RO)

Our Reverse Osmosis (RO) plant is helping us become a ‘zero water discharge’ factory. ‘Zero water discharge’ means that all our industrial wastewater will not only be treated and purified but also recycled so it can be used again in our operations. The 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 5571 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, equivalent to the amount of electricity 1,100 households would use over 12 months.

Extraction of cow water

We also extract cow water from fresh milk in our operations and use it as boiler feed water during our steam generation process. This enables us to make dual savings: energy by 0.3% and water by 4,160 m3 a year (avg.)



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 per annum equivalent to the water consumed by 310 households a year.

Rainwater harvesting

We were the first in the Nestlé world to implement a rainwater harvesting system and was awarded a Green Building Award for this initiative by the Green Building Council of Sri Lanka. This system enables us to transfer rainwater, collected on our factory roofs, to harvesting pits using pipes. The collected water is then charged into the ground to the water bed. We harvest an average of 850,000 litres of water per annum through this initiative.

New water projects

In 2019, we introduced a system that recovered soft water from our sterilizersat our UHT lines. This water is then reused as boiler feed water, enabling us to optimise our water usage and save water by 2,500 m3 per annum, equivalent to water consumed by 14 households a year, and save energy by 750 KL a year.

We monitor our water usage in our Kurunegala factory on a daily basis and report them at our Daily Operations Review meetings.
