Building near or over a strategic public sewer

If you’re building within six metres of a strategic public sewer, you will need our approval.

What is a strategic sewer?

A strategic sewer carries waste for a large number of properties. Typically, they are large (12inches/300mm or greater) in diameter, but they can be smaller in diameter and still be strategic.

How will I know if a sewer is strategic?

You can access our online mapping system.

See an example below of what strategic sewers may look like in our records. The sewers appear in bold blue for a surface water sewer and bold red for a foul sewer.

Alternatively, you can call us on 01225 526333, and we can check our records and let you know whether the sewer is strategic or not.

Why can't I build near a strategic sewer?

Damage to this type (size) of sewer could affect a significant number of households. If you would like us to assess your proposal and determine whether it's feasible or not, please contact us.
