# Siilinjärvi

Siilinjärvi (Finnish:) is a municipality of Finland. It is located in Northern Savonia, 20 kilometres (12 mi) north of the city of Kuopio, which largely surrounds Siilinjärvi. Another neighbour municipality with Kuopio is Lapinlahti. The name, in Finnish, apparently translates literally as "Hedgehog's Lake", although its etymology actually stems from a Sámi word meaning "winter dwelling". Lakes are essential part of the geography of Siilinjärvi. There are 123 lakes, and the biggest of them are Kallavesi and Juurusvesi–Akonvesi. Water area is 106.85 km$^2$, which is 21% of the whole area of Siilinjärvi.

The Kuopio Airport is located in the village of Rissala in Siilinjärvi along the Highway 9. The airport is also the home of the Karelian Air Command and the 31st Squadron of the Finnish Air Force.
Siilinjärvi is the birthplace of politician and former prime minister of Finland and European Commissioner Jyrki Katainen.

## Services
### Energy production and water supply

The use of district heating has increased in recent years. Most of the district heat is produced from the Yara plant's process waste heat and from Savon Voima's Tiprusniemi bioheat plant. At the Tiprusniemi bioheat center, heat is produced with domestic wood fuel. In addition, Sulkavantie has a LPG back-up and peak heating center.
In Siilinjärvi, groundwater is used as raw water, which is obtained from three groundwater intakes, two of which are located in the church village and one in the Toivala-Vuorela area. In addition to the municipal water supply plant, there are 15 water cooperatives in the municipality's sparsely populated areas.

### Fire and rescue services

There are two fire stations in the Siilinjärvi municipality, the North Savonia Rescue Department station and the Yara TPK station. Siilinjärvi's main fire station is located in Simonsalo at Sulkavantie 6, a few minutes' drive from the center of Siilinjärvi. The station has a 24-hour on-call service.
