Flooding and drainage

Flooding and drainage

Start preparing today before a flood happens: 

  • Check your insurance cover
  • Know how to turn off your gas, electricity and water mains supplies
  • Prepare a flood kit of essential items: water, blanket, torch etc
  • Know who to contact and how
  • Think about what you can move out now
  • Think about what you would want to move to safety during a flood

Visit the Environment Agency website for more advice on how to prepare for a flood. Also read the Thames Region Drainage Byelaws (PDF document.)

The primary responsibility for protecting property from the risk of flooding rests with the Property Owner. 

The Environment Agency takes great effort to notify property owners in flood risk areas of the risks they face. They encourage you to make plans to protect yourself and your property. We support this approach and would urge you to follow the advice of the Environment Agency. Read the Environment Agency flood warning information on the Gov.uk website for more details. 

We have access to a small number of sandbags, in the event of a flood. Unfortunately we don’t have the resources to protect every property and in these cases, priorities have to be made.  

With this in mind, we have adopted an official Sandbag Policy (PDF document.) The policy provides clear guidance to residents of the conditions that will apply when we provides sandbags. Through this policy, residents and parish councils are encouraged to obtain their own sandbags. Residents can buy sandbags from a local Builders Merchants.

Local Flood Risk Management Strategy

We are responsible for managing flood risk from local sources.

Our duties include:

  • Developing and using a Local flood Risk management Strategy
  • Assessing local flood risk
  • Setting objectives for managing flood risk
  • Measuring how well flood risk objectives have been achieved
  • Providing information on how we will work with other risk management authorities

For more information see the publications below:

We are a Lead Local Flood Authority. This means that under Section 19 of the the Flood and Water Management Act (2010) we investigate and publish reports on major flood incidents in the Borough.

We use the flood investigation policy (PDF document) to decide when to carry out a formal investigation of a flooding incident.

Why we investigate flooding incidents

We investigate flooding incidents to determine: 

  • The most likely causes
  • Which risk management authorities, for example water and sewerage companies, and highways authorities, have responsibilities to help manage flood risk
  • Whether these risk management authorities have exercised, or are proposing to exercise, their risk management functions in response to the flood incident

Published reports

Once we've finished the report we will publish the results and notify the relevant risk management authorities. 

You can view all the flood investigation reports we have produced below:

The sustainable drainage systems (SuDS) strategy sets out the long term vision for the use of Sustainable Drainage Systems (SuDS) within the Borough with a focus on managing flood risk and improving the water environment. 

The use of properly designed and constructed SuDS will promote strong, resilient, sustainable communities and reduce flood risk across the borough. 

The technical guide, included within the appendix of the strategy, includes local standards that should be adhered to by developers and their consultants when developing flood risk assessments and drainage strategies for new developments.
