Water in Norwich

Norwich has very hard water supplied by Anglian Water, typically 250 to 350 mg/l CaCO₃.
East Anglia's water comes largely from chalk aquifers, and Anglian Water's area is consistently among the hardest in the UK.
Norfolk is one of the driest parts of the country and water resources are a persistent regional concern, which shapes local attitudes to waste — relevant when considering reverse osmosis, which rejects water.
Rural Norfolk has a meaningful number of properties on private supplies, where UV disinfection and sediment filtration are the relevant products rather than softening.
Norwich's medieval and Georgian city centre includes many listed buildings where plumbing alterations require consent.

You have very hard water — among the hardest in the UK.

Limescale will be a constant in your home and a real cost in appliance life. A water softener is genuinely worth the investment here and most households who fit one notice the difference within days. At the very least, protect the boiler.

What to consider in Norwich

Based on very hard water, not on what earns us the most.

Commercial systems

Higher-capacity filtration and softening for cafés, restaurants, offices, salons, gyms and other premises, where flow rates, compliance and documented maintenance all matter.

Softeners

An ion-exchange unit plumbed into the rising main that removes calcium and magnesium entirely, giving genuinely soft water throughout the property.

Reverse osmosis

A multi-stage system that forces water through a semi-permeable membrane, removing the overwhelming majority of dissolved substances. The most thorough domestic filtration available.

Inline filters

A sealed cartridge fitted directly into a water line, most often feeding a fridge, an ice maker, a coffee machine or a drinks dispenser.

Frequently asked questions

Does my Norwich café need water filtration?

Almost certainly. Norwich has very hard water, and scale in an espresso machine's boiler and group head is the commonest cause of expensive commercial failures. Most manufacturers make water treatment a warranty condition at this hardness.

What water filtration records does a Norwich food business need?

There is no rule requiring filtration as such. What there is: water used in food preparation must be wholesome, and your food safety management system needs to show how you ensure that. Where you have filtration, its specification and maintenance form part of those records. Take specific advice from your local authority's environmental health team.
