Drains attached to houses meet up, in most cases, with drains from neighbouring houses and eventually attach to the main public sewer system.

You are responsible for lateral drains within (under) your property boundary.    

Drains outside your property boundary, shared sewers and public sewers are the responsibility of Anglian Water who is the local water and sewerage company.

If you're connected to the public sewer system they are now responsible for the pipes that are outside your property. You are still responsible for pipes within your property boundary.

You can find out more about these changes from the Anglian Water website   

Managing flood risk and drainage on developments

The Environment Agency is the leading public body protecting and improving the environment in England and Wales. The Planning Practice Guidance website offers information on site-specific flood risk assessments for developments.

If your proposal requires a full flood risk assessment, you are strongly advised to discuss the scope and content of the flood risk assessment with the Environment Agency and our Planning Team before you start work on it.   

New developments are encouraged to use sustainable drainage throughout their schemes to reduce the risk of flooding. 

Sustainable Drainage via Planning

Sustainable Drainage Systems (SuDS) are drainage solutions that provide an alternative to the direct channelling of surface water through a network of pipes and sewers to nearby watercourse. 

It is essential that the consideration of sustainable drainage takes place at the start of the design process, and that the site design is adjusted accordingly. This should ensure that the most cost effective well designed sustainable drainage which delivers the required level of functionality.    

In May this year legislation was changed to make the Lead Local Flood Authority (LLFA) a statutory consultee to planning on all major applications regarding surface water flood risk and the implementation of SuDS through planning. As stated in the ministerial statement from December 2014, all major planning applications must ensure that sustainable drainage systems for the management of run-off are put in place, unless demonstrated to be inappropriate. Currently this application does not meet with this legislation.

A Developer should: 

  • Consider how to use SuDS throughout the green spaces and highways  
  • Contact the LLFA at the earliest opportunity to discuss the SuDS design to minimise the risk of later design conflicts
  • Provide a Sustainable Drainage Assessment and a Sustainable Drainage Operation and Maintenance Plan when submitting a planning application for major development. Failure to provide either of these documents may result in your planning application being invalidated

We are working alongside Peterborough City Council on all SuDS Schemes. Please see PCC website for further information on Sustainable drainage
