Groundwater monitoring

The Environment Agency monitors groundwater levels in areas that have historically experienced groundwater flooding, this includes parts of Croydon.

Flood alert for groundwater flooding in South East London

The Environment Agency has issued a flood alert for groundwater levels in East Surrey and South London, due to higher-than-average rainfall during the Winter.

The Caterham Bourne between Woldingham and Purley is close to flowing. Properties with deep basements and low-lying land in and around these areas may experience flooding. 

You can view a map of the affected area and sign up for flood warnings by phone, text and email on the GOV.UK website.

Flooding of properties, gardens and low-lying land elsewhere is not expected at this time.

We have been taking precautions by doing frequent checks and cleaning of gullies and soakaways in the area, and of trash screens along our water courses. Landowners close to the riverbanks are reminded to keep clear the sections of river that flow through their land.

The Environment Agency is monitoring the situation, and we are working closely with them to make sure residents who may be impacted are prepared.

Visit this section to find out how to prepare for flooding. Information is also available on the Met Office website.
