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.
