Patria Group’s total water consumption (household water and lake water) increased by 96.1% in 2020 compared to 2019. This is mostly due to the large amount of lake water used in Linnavuori, but also because of the inclusion of domestic water consumption of ISP units in Belgium, Sweden and Estonia (total 5,922 m3) in the report. In Belgium, rainwater is also used for sanitation and washing, but as collecting rainwater does not affect water reserves, it was excluded from the reporting. The consumption of lake water in Linnavuori increased by 140%. Consumption always varies, depending on the number and types of engines being overhauled in different years. At the Linnavuori site, lake water is used to cool engines during test runs and to dry ovens and vacuum furnaces. The used cooling water is fed back into Lake Jokinen. Lake water accounted for 83% of total water consumption in 2020.
