Reduction of water consumption

Sika aims to boost the sustainability performance of its production sites by reducing water consumption and treating water locally. The company implements measures to reduce consumption or to use lower-grade water qualities, especially in geographic regions where water is scarce. Efficient production means closed loop cooling and switching from public to surface and ground water, reducing the amount of drinking water used in production. By reusing wastewater, Sika aims to reduce its water consumption on a larger scale.

Target: 3% less water consumption per ton and year

This includes water consumed by all Sika operating companies and units, both industrial and nonindustrial sites, whether from public utilities or from ground or surface water sources. In 2016, this target has been achieved.


In 2016, Sika used approximately 1.3 million cubic meters of water (previous year: 1.7 million cubic meters). With water consumption per ton sold down by around 22% to 0.32 cubic meters (previous year: 0.41 cubic meters), Sika significantly exceeded its target. Sika invested in various water efficiency projects at its plants worldwide during the year under review.

To reduce wastewater discharge at the Alcobendas plant in Spain, the existing wastewater treatment facility was upgraded with ceramic ultra- and nanofiltration membranes. This reduced tap water consumption by 200 m³ per month (-25%) and achieved savings of EUR 6,000 per year. The quality of the treated water allows its reuse for cleaning the loading bulk station and in the water treatment plant.

Sika Colombia’s large plant at Tocancipá implemented a completely closed water circulation that ranges from rainwater harvesting for production to the reuse of wastewater as sanitary water or, after cleaning, for crop irrigation. In addition, all organic materials are composted and used to fertilize the garden crops.
