About heavy snow, thaw, and frost

Forecast

It has snowed heavily over the past few days. More wet snow is expected on Friday, 9 January. This weekend will see moderate frost.

Consequences for water management

Over the past few days, we have put pumping stations near the treatment plants to prevent them from freezing. We put the automated weirs to a fixed position to prevent them from freezing and failing.

Melting snow

On Thursday, 8 January, it will thaw and rain or snow locally. As the fallen snow melts slowly, the water will gradually seep into the ground. Some of it will replenish the groundwater and some will end up in the water system. One centimetre of snow is roughly equivalent to 1 to 1.5 millimetres of precipitation. The amount of snow in our region is equivalent to approximately 20 to 30 millimetres of precipitation. Water levels may rise if the snow melts quickly due to rain. This is normal. We will gradually drain this water. We do not expect any problems due to the melting snow. The wind has blown a lot of snow into ditches. watercourses covered in snow do not cause any problems towater drainage - the water simply flows underneath.

Ice

We do not expect prolonged severe frost at the moment. Therefore, we are not yet taking any measures to improve ice growth.
