Water and waste water flows

Large amounts of water are used for cooling in various tyre manufacturing processes. The Nokia plant

takes its cooling water from the adjacent river Nokianvirta. Used cooling water, as well as rain water, is

first run through oil separating wells and then back to the river. The cooling water is never in contact

with any chemicals used in the manufacturing process, and therefore it can be returned to the river. No

numeric targets can be set for cooling water consumption as it depends on the temperature of the river

water. The amount of cooling water released from the plant to the river totalled 24,042 m3 per day in

2007. The waste water of the plant (process and sanitary water) is pumped to the Nokia city sewage

treatment plant. In 2007, the volume of waste water pumped to the city sewage system was 200 m3 per

day. Consumption of water taken from the Nokia city water supply network stood at 196 m3 per day.

The waste water pumped to the city sewage system and the cooling water run to Nokianvirta are tested

annually in accordance with the environmental permit (since 2007). A plan concerning the recovery and treatment of fire fighting water must be prepared by the end of 2008.
