Remember to take care of your sewer's health.

Things that don't belong in the toilet can cause blockages and leaks!

Your water fee buys you more than just clean tap water. Water utility companies work hard daily for the environment by cleaning your sewage water. The harder you make the cleaning process, the more expensive it will become.

Deep ground water from Kurikka

Finding freshwater sources in costal areas has always been challenging. Vaasa takes it's water from Kyrönjoki river, but due to the frequent changes in water quality, the process of cleaning the water is both difficult and costly. 

To provide a growing city with clean tap water in the future, Vaasa Water has begun looking for new freshwater sources. One such source, which shows promise, can be found 70 km:s away, near the town of Kurikka.

When drilling for ground water in Kurikka, geologists discovered massive renewing water reserves deep down, in what today is estimated to be some of the oldest valley structures in the whole world. Brittish geologists have taken interest in the project and helped create a water monitoring system.

Below is a video made by BBC World Services that explains it all.
