Diversion of public sewers

If there is a public sewer within your proposed development site, a diversion may be required to allow your development to progress.

Developers with an interest in land that contains public water or waste water assets can arrange for the alteration or removal those assets to allow development work to progress. The process of altering or removing public assets to facilitate development is known as a diversion.

All or part of the diversion works may be contestable in which case the developer should be given the opportunity to undertake the works or employ a suitably qualified third party contractor to undertake any contestable elements.

In cases where the water company carries out some of the diversion work, it is only entitled to recover costs reasonably incurred.
