Groundwater flooding in the Candovers and Old Alresford

Flood Alert

The groundwater level at Preston Candover is high and rising, although the rate of rise is just starting to slow. In the last 24 hours it has increased by 0.1m. This week, we expect groundwater to prevent septic tanks from operating effectively in Old Alresford. Some properties are experiencing cellar flooding in Preston Candover. Over the next 5 days, small amounts of rain are expected each day. Groundwater will rise for at least the next 8 days. Without further heavy rainfall in that time, it may just peak below the level where cellar flooding affects a larger number of properties in the Candovers and in Northington. We continue to monitor the forecast. We would like communities to prepare for groundwater flood impacts over the next few weeks. This Flood Alert will be updated by 12:00 on Thursday 27/02/2020.

This information last updated 3:43pm, Thursday 20th February.
