The groundwater borehole level at Clarendon is 74.2m AOD and at Queen Manor Farm is 70.1m AOD. Both levels are continuing to rise following all the recent rainfall. We believe there is a possibility of groundwater flooding in Cholderton, Newton Tony, Allington, Boscombe,Idmiston, Porton, Gomeldon and the Winterbournes. Residents are advised to prepare property flood resilience measures and ensure that pumps are working where they have been installed. Residents may experience problems flushing toilets and have issues with septic tanks. Unsettled conditions and moderate rainfall is forecast by the Met Office over this coming week with periods of sunny spells. We can expect levels to increase slowly throughout this period. Some borehole information can be found at We continue to monitor the groundwater situation carefully and will update this message on Monday 24/02/2020 or as the situation requires.
