Dorset Council Issues Urgent Warning to Private Water Supply Users Following Heavy Rainfall
DORSET – Local authorities have issued an “Important Notice” to residents and businesses relying on private water supplies, warning of a significantly increased risk of contamination following the recent period of intense rainfall.
With heavy downpours sweeping across the region, Dorset Council is urging vigilance for those who source their water from wells, springs, boreholes, or surface-water systems. Excess rainwater can act as a vehicle, washing soil, animal waste, and agricultural pollutants directly into water sources, potentially bypassing standard natural filtration.
Why the Risk is Rising
The primary concern for health officials is the introduction of harmful pathogens and runoff into the domestic supply. Heavy rain can lead to:
- Increased Pathogens: A spike in bacteria such as E. coli and parasites like Cryptosporidium.
- System Overload: Runoff from nearby fields or overflowing septic tanks can overwhelm private systems.
- Reduced Filtration: Increased turbidity (cloudiness) can make UV treatment units and filters less effective at killing germs.
These contaminants pose a serious health risk, particularly to vulnerable groups including children, the elderly, and those with compromised immune systems.
Immediate Action for Residents
Dorset Council recommends the following “Right Now” protocol if you suspect your supply has been compromised:
- The “Look and Smell” Test: Do not drink the water if it appears discoloured, cloudy, or has an unusual taste or odour.
- Boil as a Precaution: If you have any doubts, boil all water used for drinking, cooking, brushing teeth, and washing salads.
- System Inspection: Physically check your source, tanks, and pipework for signs of flooding, damage, or surface water ingress.
- Maintenance Check: Ensure all treatment systems, such as UV lamps and sediment filters, are powered on and functioning correctly.
Seeking Assistance
If you notice a persistent change in your water quality or believe your supply has been affected by the recent weather, you are encouraged to contact Dorset Council’s Environmental Health team.
”Rain can wash pollutants into sources unexpectedly. Staying alert is the best way to look after your household’s safety,” the Council stated.
