Where does the water for Southampton come from?

The majority of Southern Waters supply comes from groundwater (70%), predominantly from the chalk aquifer which is widespread across our region. A further 23% comes from rivers and the remaining seven per cent from surface water reservoirs owned by the company.

Water Rates Southampton

Water rates in Southampton will depend on if your home has a water meter or not. You can find out whether your Southampton water rates are metered by looking at your water bill. Homes with metered Southampton water rates will have a meter number available on their water bills.

Homes that aren't metered won't have this of course, but they will have the rateable value of the home instead. The rateable value part of your Southampton water will have been determined by the local council in the 90s and unlikely to have changed significantly since then unless you have a newer property.

If you don't have a bill at the ready or have just moved into your home, you can look around your house or in the front garden for a meter. Sometimes the meter can 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 Southampton residents are being charged result in an average water bill of around £418 a year. This amount combines both sewerage costs and water supply.

Southampton Water Hardness

Southampton's water hardness is rated as Very 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 Southern Water's supply area, Southampton water picks up minerals, such as magnesium or calcium, on the way to your tap.

The very hard rating of Southampton's waters means that the water in your home is likely to lead to scaling in sinks, dishwashers, kettles, and loos.

  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: Try to avoid over-filling your kettle with water. Make sure that you 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 the scale.
  3. Dishwashers: Take advantage of the built-in water softener. Make sure you regularly top it off with dishwasher salt in the appropriate compartment.

Can you drink the water in Southampton?

Yes! You can drink the water in Southampton without concern. Southampton's water meets very high standards making it safe to drink. The UK Drinking Water Inspectorate has scored Southampton's water quality a 99.96% in overall mean zonal compliance, meaning that your water is very safe to drink. It is not necessary to boil or filter Southampton's water further in order to make it potable.

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

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

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

Southampton water problems can include anything from a burst water main or flooding to having no water in your home. This is why you should make sure you know what to do and who to contact regarding water emergencies.

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

  1. If you are out and about, call or tweet Southern Water
  2. If you are near a computer, go to the "Need help?" section of Southern Waters website, where you can report a leak or flooding, or alternately call their Leakline.
