During the 2024 Devon outbreak, some residents required hospital treatment, and hundreds more fell ill after the local water supply became contaminated with Cryptosporidium, a parasite that can cause stomach sickness and diarrhoea.
South West Water (SWW) has admitted supplying tap water that was unsafe to drink after a parasitic outbreak in Devon left four people in hospital and over 140 infected with cryptosporidium. The first cases were confirmed by the UK Health Security Agency (UKHSA) on 14 May 2024—but at that point, SWW assured customers the water was safe.
Just a day later, on 15 May, the company confirmed traces of the parasite in the supply network and issued a boil water notice to around 16,000 homes and businesses in and around Brixham. The outbreak triggered a diarrhoea-type illness in more than 140 people, with four requiring hospital treatment.
Some properties were under the boil water advisory for 54 days, with the warning only lifted on 8 July. SWW pleaded guilty to breaching the Water Industry Act 1991 at Exeter Magistrates’ Court and issued a “full and unreserved apology” for the disruption. Sentencing is scheduled for a later date.
The timing couldn’t have been worse—striking just ahead of the May Bank Holiday, the crisis caused major disruption for residents and dealt a heavy blow to Devon’s local tourism industry.
Make The Switch to Coconut Carbon Filtered Water.
For many households, this is why point-of-use filtration systems are becoming increasingly popular
An ultrafiltration undersink purifier fits discreetly under the kitchen sink and filters water directly as it’s used. Ultrafiltration membranes are designed to remove very fine contaminants — including bacteria, parasites and microscopic particles — while still allowing natural minerals to remain in the water. They remove harmful impurities, including lead, mercury, microorganisms, and VOCs (volatile organic compounds), which is crucial for families with children.
The result is fresh, filtered drinking water straight from your tap, without the ongoing expense and waste of single-use plastic bottles. Better Taste and odour: They eliminate the unpleasant chemical smell and taste of chlorine used in municipal water disinfection.
It’s not about worrying about every possible contamination event. Incidents like the one in Brixham are relatively uncommon. But they do show why many families prefer having an extra layer of protection at home.
With an undersink ultrafiltration system, you’re not only cutting down on plastic waste — you’re also giving yourself and your family a simple, reliable way to ensure the water you drink every day is properly filtered.
