What is hard water?

Water which contains calcium and magnesium compounds is called hard water. When rain water - which is naturally soft - seeps through the ground it picks up minerals from soil and rocks it passes through. Much of the drinking water in Europe comes from above ground sources and a great deal also comes from underground geological formations that store rainwater. The rainwater seeps through porous strata such as sandstone and chalk. These underground water sources are then tapped as sources by municiple water companies which are distributed to our homes.

Please see the benefits page to see the effects of hard water on you and your family.

Water Distribution

Water is delivered to our homes through various methods and distribution networks. These networks are made from cast iron, plastic or cement. Residues from treatment and corrosion of the pipes can sometimes settle in areas of low water flow. When deposits are disturbed, this can result in discoloured water arriving through the pipes into homes.

Water Treatment

Water is treated at treatment plants before it gets to all of us. There are three main processes in the treatment process:

  • Clarification: This is a process which removes silt, algae, colour, magnesium and aluminium, and various other matter which may be found in raw water. A chemical called coagulant, which is usually Iron or Aluminum salt is added to the water. Making the material coagulate into larger pieces to be removed easier.
  • Filtration: The water is then filtered through beds of sand or other material where particles are trapped.
  • Disinfection: The most common method of disinfection is with the use of Chlorine. Chlorine is used to kill bacteria in the water supply, water companies need to leave a portion of the chlorine in water to ensure that bacteria is controlled on the way from the treatment plant to our taps.
