Groundwater flooding for the Wylye Valley at Wilton

Groundwater levels in Salisbury Plain are beginning to fall but remain high. Areas that could be affected include: Wilton. The groundwater level at Stoford Cross borehole has fallen to 68.51m. We have had a period of drier weather, but the forecast is unsettled for the coming days which may cause falling levels to rise. Residents are advised to prepare property resilience measures and ensure that pumps are working where they have been installed. Residents may experience inundation of septic tanks and sewer systems. Properties may experience flooding in cellars in affected areas. Flooding of roads is expected, take particular care when driving, both for your own safety and to prevent flooding to others. Roads may have become damaged by floodwater. Where groundwater is near the surface, intense rainfall will lead to surface water flooding. We will continue to monitor the situation closely.
