Our region received 260 per cent of its historical average rainfall during the winter of 2013–14 after some of the worst weather on record.

Southern Water - flooding in Lewes

During the extreme weather in our region early in 2014, we had to tanker and pump stormwater to prevent it overwhelming our sewers and people’s homes.

Damage caused by flooding in 2007 cost the UK economy
£3.2 billion. Following these floods, Sir Michael Pitt was asked to carry out an independent review by the Government into what happened and what should be done differently in the future.

We're combating the increased risk of sewer flooding:

  • We're investing nearly £80 million in flood protection schemes between 2010 and 2015, which will see a 20 per cent increase in the capacity of new sewers
  • This includes £20 million on sewer improvements in Portsmouth to help protect the city from flood damage during storm conditions
  • It also includes nearly £10 million in updating sewer plans, computer models and drainage area plans to monitor how our network can cope with changing weather patterns in the future.

Surface Water Management Plans

Recommendations from the Pitt Review included the production of Surface Water Management Plans for high risk areas. 

Defra has funded the development of a number of Surface Water Management Plans in our region.

Local authorities

Local authorities are responsible for producing the plans, in collaboration with the Environment Agency and the water industry.

We're currently working with the relevant county councils and unitary authorities to help develop these plans. Read more about those that are under way below.
