Hard Water

Having hard water isn’t something you should worry about, it means the water we supply to your taps is rich in minerals from the natural limestone in the area

Our water is proper 'ard

Well, maybe not as hard as Ellis Genge, or figuring out your way around the road closures by Temple Meads. Pop your postcode in and have a look how hard the water is in your area.

Here’s the hard truth

Hard water isn’t harmful to your health. In fact, some argue that it could actually be beneficial because of all those natural minerals you’re filling your body with. On the other hand, it’s those very minerals that can cause limescale build up, can reduce the lifespan of your appliances (your kettle, dishwasher, washing machine), and generally be a bit of a pain in the backside.


Really, the most likely impact of having hard water is using a little more detergent than normal to wash your clothes, or a little more shampoo than usual to wash your hair. Hard water is also the reason you might see that ‘film’ on top of your cup of tea if you don’t stir it enough (hope that answers Doc Brown’s question)

“But how can I reduce the hardness of my water?”

You can’t get rid of the hardness in your water easily, but there are a few simple things you can do to make sure your appliances can live a little longer:


If used regularly, appliance cleaners and descalers (usually found in supermarkets), can 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, and it's usually really cheap and easy to find any supermarket. The salt acts as a water softener and reduces the likelihood of scale build up.

  • Consider fitting water filters to your taps with water softeners (but this can be pricey)

Water filters and water softeners can be fitted to internal pipework to reduce minerals in your water. This can be effective but the cost of filters can be quite high.

Due to the presence of limestone in the Bristol area, most of the water we provide natually hard, or very hard. If you'd like to know more about water hardness, we have this handy leaflet you can check out here

You can also find out more about how to reduce hard water here 

You can check the hardness of your water by entering your post code in the search box at here and then following the instructions on the 'Water Quality' link in the top left hand corner of the map.

More information on water hardness can be found by typing your postcode here.

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.
