Where does Ewell water come from?

85% of SES's water comes from underground aquifers sourced from the chalky regions of the North Downs, or the greensand deposits to the south of the Downs. The rest of the water comes from SES's reservoir at Bough Beech. The water from both of these sources are closely monitored and filtered in order to ensure that it is of a safe and high quality before it reaches your home.

Water Rates Ewell

Water rates in Ewell depend on whether your home has a water meter or not. You can easily find out whether your Ewell water rates are metered by looking at your water bill. Homes that have a meter along with the associated water rates will have a meter number listed on their water bills.

Homes that are not metered won't show a meter number, but they will have the rateable value of the home instead. The rateable value part of your Ewell water rates will have been determined by the local council in the 90s and is unlikely to have changed much since then.

If you've just moved in or you don't have a bill handy, you can look outside your house or in the front garden for a meter. Sometimes the meter may be located inside your house near the stop tap.

If you want to read more about water meters check out Selectra's essential guide to water meters.

The average water rates Ewell residents are being charged result in an average water bill of around £374 a year. This amount combines both water supply and sewerage costs.

Ewell Water Hardness

Ewell's water hardness is rated as hard water. While rainwater itself is relatively soft, water hardness can change through the water cycle. Due to the way water filters through rocks in SES Water's supply area, Ewell water picks up minerals, such as magnesium or calcium, on the way to your tap.

Ewell water's hard rating means that the hard water in your home will lead to scaling in kettles, sinks, dishwashers and loos. Below are some ways to help mitigate hard water furring or scaling in Ewell.

  1. Baths, sinks and toilets - Use an acidic sanitiser regularly (available in local shops) to clean susceptible surfaces in order to clear limescale deposits.
  2. Kettles - Do not overfill your kettle with water, using only as much as you need at that moment. Make sure that you also clean your kettle by half-filling and adding two tablespoons of white vinegar, leaving it for four hours in order to loosen scale build-up. Rinse and repeat to remove scale.
  3. Dishwashers - Take advantage of the built-in water softener. Make sure you regularly top off it off with dishwasher salt in the appropriate compartment.]

Can you drink the water in Ewell?

Yes! You can drink the water in Ewell. The UK Drinking Water Inspectorate has scored Ewell's water quality a 99.96% in overall mean zonal compliance, meaning that your water is safe to drink. You don't need to take any further steps such as boiling or filtering your water in order to make it potable or safe.

If you notice a change in taste or smell of Ewell's water this may be due to one of the following reasons:

  1. Chlorination is a safe way to ensure hygiene throughout the pipe network.
  2. Seasonal changes in water characteristics can infuse Ewell water with an earthy smell or taste.
  3. Plumbing can contribute to the taste of your household water, adding metallic, salty or rubbery hints.

You should not hesitate to contact SES Water if you have questions about your water's taste, smell or appearance.

Ewell Water Problems

Ewell's water problems can include anything from burst water mains, flooding or even having no water supply in your home. This is why you should make sure you know what to do and who to contact in the event of a water emergency.

If you notice a water leak or flooding outside your Ewell property, you need to do one of the following:

  1. If you are out and about, call or tweet SES Water
  2. If you are near a computer, go to the "Noticed a problem?" section of the SES Water website and report a leak or issue. If there is an emergency or an immediate risk to health or safety, you should call their emergency number.

Ewell No Water

If you have no water in your home, you need to find out if the issue is to do with your home plumbing or an SES Water outage impacting Ewell.

  1. Check the "In Your Area" or "Report a supply issue" sections of the SES Water website for any information explaining why you have no water
  2. Ask your neighbours whether they have the same issue as you
  3. Check that your stop tap is open
  4. If you have no water is it only no cold water or no hot water. If you have cold water but no hot water, the issue will be with your home plumbing and not the water company

    If there is no cold water, not even a trickle, contact SES Water for assistance.

Ewell Water Discolouration

If the water in your home is discoloured, the issue might be an SES Water issue impacting Ewell.

  1. Changes to the colour of the water in Ewell may happen after a burst pipe has been repaired
  2. Or, SES Water could have been carrying out upgrade work on the pipes in Ewell
  3. Water Discolouration is not harmful and can often be cleared by running the cold water tap until it becomes clear
  4. If there is no improvement after trying this, you can contact SES Water for assistance.
