If your average water consumption is 150 m³ per year, your water softener processes 150 m annually³ x 133.5 grams = 20.03 kilograms of limescale removed from your water!

Soft water in Zwolle

The water hardness in Zwolle is around 7.5 dH. This means that the water in Zwolle is fairly hard. Nevertheless, even this relatively soft water can cause limescale build-up and other adverse effects. Soft water is water that is free of, or has had the calcium removed from, limescale. As soft water does not occur naturally in the Netherlands, a water softener is a good solution for adverse effects of limescale to get rid of.

Water hardness in the rest of the country

The Water hardness in the Netherlands varies considerably: it ranges from just over 2 dH to as much as 15 dH. This is because water is sometimes sourced from low-calcium sources, such as surface water (rivers, streams) or water from the dunes. The water extracted from these sources generally has a low, natural hardness. However, in the Netherlands, groundwater is usually used. This almost always results in much higher water hardness because this water is found in calcium-rich soil layers. This is caused by the remains of shellfish that lived here thousands of years ago – when the Netherlands was still under water.
