Water | Patria

Patria Group’s total water consumption (household water and lake water) increased by 10.3% in 2021 compared to 2020. Domestic water consumption decreased by 4.3% so the total water consumption increased due to lake water use in Linnavuori (figure 5). 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 13.1%. Consumption varies from year to year, 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 85.6% of total water consumption in 2021.
