Water Hardness

Water hardness is a natural characteristic of water. Whether it is hard or soft depends on the type and number of minerals within the water that have been picked up on it’s journey through the earth, to your tap.

Most water in this area is classified as hard

Due to the presence of limestone in the Bristol area, most of the water we provide is naturally hard, or very hard. To check the water hardness in your area, type your postcode below:

Hard water can cause a few problems...

Hard water is not harmful to health, in fact some argue that it may be beneficial, however due to the high mineral content, hard water can cause limescale to build up, which over time can reduce the lifespan of appliances and generally, be a nuisance.

Some of the more likely impacts will be having to use more detergent or soap when you're washing your clothes or your hair, having limescale build up around the elements of your kettle and also having a thin 'film' on the top of hot drinks.

If you'd like to know more about the causes and issues associated with hard water, we have created a hard water information sheet.

Reducing Hard Water

Simple tips that will help reduce the impact of hard water.

Due to the mineral content, hard water can, over time, increase wear on dishwashers, kettles, washing machines and steam irons. To keep white goods and household appliances in good working order, follow these simple tips.

Descale your appliances regularly

If used regularly, appliance cleaners and descalers, such as those available at most supermarkets, break down the mineral build up caused by hard water.

Keep your dishwasher salt topped up

It's easy to forget to top up the salt in your dishwasher. The salt acts as a water softener and reduces the likelihood of scale build up.

Consider fitting water filters to your taps

Water filters and softeners can be fitted to internal pipework to reduce minerals in your water. This can be beneficial for severe hard water, but the cost of filters may be quite high.

Hard water is mineral rich

Hard water isn't all bad news however. Due to it's rich mineral content, there are many who believe hard water can provide health benefits.

If left to dry naturally hard water may leave a powdery white residue on draining boards and other surfaces. Black, green, orange or red staining of tiles and other surfaces in the bathroom and kitchen is usually caused by airborne spores.

All of the water we supply is classed as either hard or very hard. Water hardness is a natural feature and is a result of the geology of our area being primarily limestone.  Minerals such as calcium and magnesium dissolve into the water as it moves over and through the ground. The level of these minerals in the water determines the water hardness.
