Can I divert a sewer?

If there are existing sewers crossing a new development site which cannot be designed to avoid them, the sewers must be diverted. You can propose a scheme and ask us to consider whether a diversion is possible. Any diversionary works are done at your cost.

When a scheme is agreed we'll complete the works on a fully rechargeable basis and recover all costs from you. In some cases and if you're suitably qualified, we'll let you complete the work under a legal agreement with us. In this case we will require a deposited sum as a surety against poor workmanship. This sum is equivalent to 10% of the cost of the scheme or £5,000 minimum. To apply, download the application form.
