We aim to increase water efficiency, both in how we build and in the end use of what we build. Where applicable we substitute potable water for alternative quality grades.
Skanska has a great impact on water usage, both during the construction phase and with the end use of buildings and infrastructure. Water is recognized as a priority area on the Skanska Color PaletteTM.
Water in the built environment
The built environment requires water for many different purposes – human consumption and hygiene as well as for construction processes and production of materials. Water use in the built environment is a local factor.
The challenge in water management is to recognize that different qualities of water exist and to use each one in the most efficient way and for the most appropriate applications.
In 2016, Skanska for the first time collected water data on a Group level. In 2017, Skanska scored Leadership level (A-) in the CDP water questionnaire. Skanska is continually working to improve Group water management and reporting.
Example of innovative water efficiency solutions
Skanska integrates water-efficient solutions into projects. For example, the Botanica K Residential Development project in the Czech Republic uses an innovative water solution for grey water management. Treated water from washbasins, bathtubs and showers – along with collected rainwater – is used for flushing toilets. This, combined with other water efficiency solutions, reduces potable water consumption by about 40 percent.
