Planning Permission for Drainage Works

When it comes to minor repairs, routine maintenance, or very small projects on your property's drains and sewers, you typically won't need to apply for planning permission. However, for more substantial undertakings, you might be required to submit an application.

Some projects, even those more involved than just basic repairs, might be covered by what are called 'permitted development rights'. These rights essentially allow you to carry out certain types of work without needing a full planning application. Nevertheless, it is absolutely vital that you confirm with your local planning authority whether these specific rights have been removed for your particular property.

Ownership and Responsibility

Before you even consider modifying or maintaining any part of a drainage system, you must first establish who owns it and who holds responsibility for it. This is a critical step because:

• Your drains, sewers, and even manholes could be shared with your neighbours.

• Alternatively, they might belong to the local water and sewerage company (often referred to as the 'sewerage undertaker' in official terms).

Failing to verify these crucial details or neglecting to comply with all relevant standards could lead to legal action and expensive corrective work, all of which would be at your own expense.

If you're ever unsure about any aspect, your local planning authority is always available to offer you further guidance.
