Water Rates Harlow

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

Homes that are not metered won't, but they will have the rateable value of the home instead. The rateable value part of your Harlow water rates will have been determined by the local council in the 90s and will probably not 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 Harlow residents are being charged result in an average water bill of around £417 a year. This amount combines both water supply and sewerage costs.

Harlow Water Hardness

Harlow 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 Harlow Water's supply area, Harlow water picks up minerals, such as magnesium or calcium, on the way to your tap.

Harolow's water hardness rating means that the hard water in your home will lead to scaling in kettles, sinks, dishwashers and loos. There are ways to mitigate hard water furring or scaling in Gloucester.

  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: Avoid overfilling your kettle with water in general. 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.

Yes! you can drink the water in Harlow. Harlow water meets the highest standards to make the water safe to drink. The UK Drinking Water Inspectorate has scored Harlow water quality a 99.96% in overall mean zonal compliance, meaning that your water is safe to drink. It is not necessary to boil or filter Harlow water to make it potable.

If you notice a change in taste or smell of Harlow 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 can infuse Harlow water with an earthy smell or taste.
  3. Plumbing can also contribute to the taste of your household water, adding metallic, salty or rubbery hints.

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

Harlow Water Problems

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

  1. If you are out and about, call or tweet Affinity Water
  2. If you are near a computer, go to the "report a leak" section of Affinity Water and fill out the online form.

Harlow 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 a Affinity Water outage impacting Harlow.

  2. Ask your neighbours whether they have the same issue as you.
  3. Check that your stop tap is open
