Where does Hertford water come from?

Affinity water gains 60-65% of its supplies from underground chalk aquifers. When the aquifer's supply lowers in the summer months this is then supplemented with alternative water sources such as boreholes until rainwater sufficiently restocks the aquifers.

Water Rates Hertford

The water rates that apply to your Hertford home depend on whether your property has a water meter or not. You can easily find out whether your water rates are metered by taking a look at your water bill. Homes that have metered Hertford water rates will have a meter number listed on their water bills. Alternately with some suppliers, the account number may begin with MC for metered customers, or UC for unmetered customers.

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 your home has water meters, it is important that you give frequent meter readings to your supplier so that they can bill you for your exact usage instead of an estimation.

Homes that are not metered won't have these, but they will have the rateable value of the home in their place. The rateable value part of your Hertford water rates will have been determined by the local council in the 90s and will probably not have changed much since then. This rateable value uses factors such as your property's size, the availability of services, and the area in which it is situated to create an estimated consumption value of your home, which is then used to generate your bill.

Are you interested in having a water meter installed? Check out Selectra's essential guide to water meters to find out if this is the right choice for you, and how you can go about getting one.

The average water rates Hertford residents are being charged result in an average water bill of around £417 a year. This amount combines both water supply and sewerage costs.

Hertford Water Hardness

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

Hertford's very hard water rating means that the water in your home will lead to scaling in kettles, sinks, dishwashers and toilets. There are ways to mitigate hard water furring or scaling in Hertford.

  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 water as you need. 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 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 Hertford?

Yes! You can drink the water in Hertford. Hertford water meets the highest standards to make the water safe to drink. The UK Drinking Water Inspectorate has scored Hertford 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 Hertford water to make it potable.

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

  1. Seasonal changes can infuse Hertford water with an earthy smell or taste.
  2. Chlorination is a safe way to ensure hygiene throughout the pipe network.
  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.

Hertford Water Problems

Hertford water problems can include anything from burst water mains, flooding or even 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 Hertford property, you need to do one of the following:

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

Hertford 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 Affinity Water outage impacting Hertford.

  1. Ask your neighbours whether they have the same issue as you.
  2. Check that your stop tap is open.
  3. Check the "In Your Area" sections of the Affinity Water website for any information explaining why you have no water.
  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 Affinity Water for assistance.
