Developer Services Sewerage Services Alteration or Removal of a Public Sewer or Associated Apparatus

Anyone with an interest in any land which contains a public sewer or associated apparatus has the right to request the alteration or removal, including diversion (generally referred to throughout this document as diversion) of that apparatus to accommodate a proposed improvement of that land (e.g. development or change of use).  This right is granted by Section 185 of the WIA91 and extends to anyone with an interest in adjacent land where the presence of public sewerage apparatus would hinder proposed improvement.  This does not apply to sewers in any public highway.

You can request an alteration, removal or diversion of apparatus by serving a formal Notice which is included with the Application Form.  We have a duty to consider such a request except to the extent that the request is unreasonable.  Any request which would result in a reduction in the performance of the apparatus, or would render it unusable or inaccessible, would normally be considered to be unreasonable.

Please refer to our Guidance Notes for further information.
