Application forms, guidance & agreements

If you are planning to discharge anything other than domestic waste into a drain that’s connected to a public sewer, it is likely that you’ll need to obtain consent from us before you commence any discharge. Please contact your appointed Retailer to discuss this.

You should be aware that from 1st April, the retail water market for business customers is changing. It will work in a similar way to other utilities in which you will have the freedom to choose a retailer for services such as billing and customer service. For more information on the changes and advice on how to choose a retailer go to Open Water website.
