Groundwater issues in your area
Although we’re not responsible for groundwater flooding, we do everything we can to help reduce its impact on our communities. Learn more about who’s responsible for different types of flooding.
Groundwater levels are currently very high. We're monitoring the sewer network closely. While we use tankers to manage the situation, you may notice an increased Southern Water presence in your area. Tankers is a way we can actively prevent flooding and impact to the environmental.
Traffic lights may also be in place during this time, with some road closures until further notice. While we do our best to keep noise and disruption to a minimum, we are sorry for any inconvenience this will cause.
If you do notice any spills, or are impacted by restricted facilities or flooding, please contact us on 0330 303 0368.
You can find more details about each area impacted by high groundwater below. We continue to keep in close contact with your local Parish Council about this activity.
