FloodingLast updated: 29 January 2014 15:11 UK
Although serious flooding events are rare, Portsmouth City Council still needs to be prepared to respond to the risk of flooding at all times. You can download the council's two flood response plan booklets below.

Portsmouth City Council's drainage team is responsible for investigating any flooding in Portsmouth, and works to prevent future flooding by improving drainage throughout the city.

If there is risk to life or serious risk to property or the environment as a result of flooding, call 999.
There are different types of flooding, described below, as well as advice on how to prepare for, and what to do during and after a flood.
Surface water flooding
The council's Surface Water Management Plan identifies and prioritises the areas of Portsmouth at greatest risk from surface water flooding, defined as heavy rainfall creating more water than the drainage system can cope with. Most flooding in Portsmouth is caused by surface water which, by its very nature, is very difficult to predict. This makes providing accurate and timely warnings difficult.
Drains in the gutters at the side of the road, known as gullies, can overflow in times of heavy rainfall. Gullies may not appear to be coping with heavy rainfall, but do allow some time for water to subside and then, if the drainage does not improve, let us know using the gullies online form or phone the city helpdesk on 023 9283 4092.
Burst water mainsPortsmouth Water supplies water to the city, and is responsible for all pipework up to and including the stopcock. To report a burst water main, phone Portsmouth Water on 0800 434 610. Use the Portsmouth Water online form to report smaller leaks.
Portsmouth may be susceptible to coastal flooding, but it is relatively easy to predict. When the Environment Agency warns of tidal flood, the council deploys floodgates and flood boards in Old Portsmouth. Follow the link for more information on the council's approach to coastal flooding. Portsmouth City Council is also a member of the Eastern Solent Coastal Partnership.
Gov.uk also manages the risk of floods and coastal change.
What you can do
We suggest all residents living in flood zones complete a flood plan. The plan collects together essential information you will need in the unlikely event you are flooded. This will help you make the right decisions before and after a flood. For example, Portsmouth City Council do not supply sandbags, so you will need to buy them from your local DIY store. The Environment Agency offers useful advice in their booklet 'What to do before, during and after a flood'.
If you would like any help with your flood plan please contact us, or phone the Environment Agency's Floodline on 0845 988 1188.
Residents in floodzones can register with the Environment Agency's Floodline to receive flood warnings, or you can automatically receive flood alerts for your area by downloading this facebook app. Consult the Met Office for heavy rain forecasts and flood alerts.
