Repairs in the pipeline, hydraulic impacts or heavy water extraction may loosen deposits from the inside surfaces of the pipeline. These deposits may tint the water brownish and cloudy. 

The water clears normally fairly quickly if you let it run for a while from the tap or wall hydrant. Using brown water is not dangerous but you should let it flow until it clears before use. If the water does not clear up in a reasonable time, contact Oulu Waterworks customer service, tel. 08 558 43800.  

If the tap water in building pipeline is green, it normally indicates a leak in the heat exchanger of domestic hot water and means that hot water in the district heating network is mixing with domestic water in the heat exchanger. In fact, green color is used in the district heating water to indicate possible leaks. District heating water does not usually leak from the heat exchanger to domestic cold water and the coloring as such is not dangerous. However, the district heating water has been circulating in the pipe network for a long time, you should not use it and the defect should be repaired without delay.
