Groundwater flooding in the Alton area

Flood alert

Groundwater levels remain high and are rising at our Farringdon borehole near Alton.
Groundwater levels remain above normal levels for this time of year and are at a level where communities may be affected by groundwater flooding within the next few weeks.
The catchment remains sensitive to rainfall due to the saturated ground and levels may start to increase again if we receive further rainfall. Low-lying land, gardens, roads and cellars will therefore continue to be at risk of flooding. Due to the nature of groundwater behaviour, this situation could continue for several weeks or longer.

We are continuing to monitor groundwater levels and will update this message on 21/03/2024, or as the situation changes.
