I spotted this old fire hydrant a while back. If it's still in use, I don't know, but I guess it is. Nowdays, the firemen's water supply mainly comes from manholes. I did a quick search on the name on the hydrant and found out that Esco is the factory where these hydrants (and other valves and fittings) are being made. The factory is actually situated in Kongsberg, a city a 30 minutes drive away from Øvre Eiker.
