Pre-Development enquiry applications

For a full capacity study for proposed developments, our Pre-Development Enquiry service will provide information regarding the impact the proposed development will have on our existing sewerage network and its ancillary assets, together with identifying any associated costs involved with upgrading or diverting our assets to provide sewerage services for the new development.

Before submitting your request please read the Pre-Development Enquiry Guidance which explains the procedure in more detail. Supporting layout and location plans should also be attached to your Pre-Development Enquiry Application form.

Building over or in close proximity to a public sewer

If you are planning any development work or construction, such as a property extension, you will need to check the location of the public sewers with us.

Should the location of a public sewer prevent land development or a property extension, it may be possible to build over the sewer, this will be subject to our approval.

If you have any queries regarding Building Over of Sewers please contact NWL on 0845 717 1100.

New sewer connection (S106)

Northumbrian Water Ltd offers two options for making a new connection to an existing sewer:

1) NWL’s approved contractor can carry out the work for you at your expense

Or

2) You can request that NWL approves a contractor of your choice to carry out the work (Please note NWL’s consent is not guaranteed).

In both cases a completed application form must be submitted to NWL along with the appropriate supporting documents and the appropriate fees. Please note that dependent on the area to be drained to the public sewer you may be required to complete a Pre-Development Enquiry prior to making a connection application.

Adoption of a new sewer (S104)

You can make an agreement with us to adopt a sewer prior to its construction. You will need to apply for a Section 104 Sewer Adoption Agreement. On adoption the sewer will become part of our sewerage network and maintained at our expense. We follow the nationally approved document ′Sewers for Adoption 6th Edition′, published by WRC on behalf of Water UK.

Abandonment of a public sewer (S116)

In some circumstances it may be possible to close a public sewer so that it can be abandoned, which may remove a potential restriction from any future development of the site and may make any site remediation works easier. Before we consider applying to close part of the public sewer network, we need to be absolutely certain that the length being considered is no longer in use and has become redundant.

First time sewerage (S101A)

Under section 101A of the Water Industry Act 1991 (WIA 91) sewerage undertakers have a duty to provide a public sewer to resolve certain environmental issues.  This is limited to circumstances where existing drainage systems, that are not connected to existing public sewers, are giving rise, or are likely to give rise, to adverse effects on the environment and/or amenity and the most appropriate way of resolving those effects is by providing a public sewer.

Owners or occupiers of properties may ask Northumbrian Water to consider providing a public sewer in accordance with Section 101A where the sewerage system causing the adverse environmental effects, serves two or more domestic properties.

Where there are currently no or envisaged to be any adverse affects on the environment: 
a) owners or occupiers of two or more properties may apply to requisition a sewer under section 98 WIA 91or apply under section 104 WIA91 for Northumbrian Water to adopt sewers designed and constructed by the applicant
b) the owner or occupier of a single property may apply to connect to an existing public sewer under section 106 WIA 91.
