Ground water infiltration into the sewer
Groundwater is currently high enough to infiltrate the main sewer through the parish causing some households problems with their toilets and waste water removal, and causing sewage to flood onto the road.
Southern Water have responded by tankering in both Stoke and St Mary Bourne. Eight of the 24 tankers in use in North Hampshire are currently allocated to the parish of St Mary Bourne. They have also started jetting the sewer 3 times a week to remove silt build up.
