The town of Lohja acquires water from Nordkalk


More than one million cubic meters of groundwater is pumped up yearly from the underground mine. About half of the water is delivered to the municipal waterworks, where it represents 23 per cent of all raw water received. It is filtered through a sand bed before being led to the water distribution system.

The Tytyri plant itself uses some 30.000 m3 of water annually, also from the mine, but through a separate pumping station. The surplus water – about half a million cubic meters – is directed to the nearby lake Lohjanjärvi. This is mostly groundwater, but it includes a small portion of storm water gathered from the plant area. Yearly quality measurements show that the water released into the lake corresponds to household water quality.

In Tytyri, there is also The Tytyri Experience including a museum and other activities. The Tytyri Experience is operated by the city and visited by more than 10.000 people annually.

KONE Corporation’s high-rise elevator test laboratory is located in old mine shafts. One of the elevators is used to transporting visitors to the Tytyri Experience.
