Our commitment: Treat the water we discharge effectively
We are committed to treating the effluents from our operations in a responsible manner and adhere to strict quality targets for returning it to the environment. Wherever possible, we use existing municipal wastewater treatment facilities but where they do not exist or cannot meet our standards, we operate our own treatment plants.
By 2016: Implement the new Nestlé Environmental Requirements for water quality and effluent discharge in all factories.
We have strengthened our Nestlé Environmental Requirements for water quality and effluent discharge, applied by all factories to ensure we go beyond legal compliance across our operations. In 2015, we approved a spend of CHF 19.4 million on improved efficiency, water conservation measures, new and upgraded treatment facilities, and strengthened water quality requirements for effluent treatment installations. This means we have invested a total of almost CHF 400 million in water-saving projects in our factories over the last decade.
We monitor water quality and effluents on a monthly basis and we use a Water and Effluents dashboard to help us analyse longer-term trends and identify improvement opportunities.
Since 2005, water discharges per tonne of product have fallen by 56%. In 2015, it fell by 8.2% and waste water quality improved by 2.3% to 70 mg Chemical Oxygen Demand (COD) per litre.
In 2015, we received a ‘Leadership level’ CDP score of A– for our best-practice approach to managing water and mitigating water risks.
