Record Requests

Identify What you Need

  • You will need to be aware of any of our services below your site. An A4 printed record will usually allow for sufficient detail of this.
  • If a larger map is required, additional costs will apply.

Application & Payment

Record Issued

  • We will issue you a copy of our mapping records.
  • This will allow you to see the location of our existing watermains and sewers.

Record Requests


An extract of data can be obtained from NI Water’s Graphical Information System (which incorporates sewer/watermain infrastructure) by applying for a Record Request. This involves processing applications of the specified area to include the location of our infrastructure and the provision of same by means of electronic or printed copies.

Please note that the applicant is required to submit a Site Location Plan 1:1250 / 1:2500 map (LPS ACE map will suffice) with the site boundary clearly indicated in red and relative to an existing feature to allow for the specified area to be easily identified. The area where information is required must be covered in full by the site boundary outlined in red on the site location plan, failure to indicate the full area of interest will result in an application fee for an additional map.

In general most of the Record Requests processed allow for a suitable amount of detail when printed on A4. However if you request a size that does not provide a suitable amount of detail, a larger map will be required, you will be notified of any additional costs that should be paid prior to the Record Request being issued. Additional copies of our records will incur an additional cost per copy. There is a cost for this service in accordance with our current Scheme of Charges.

Standard Information Provided in a Record Request

We will endeavour to issue maps in electronic format rather than issuing printed copies, so please ensure your email address is included on all correspondence.

Maps issued by email will be in PDF file with information embedded into the record drawings for the selected area. You will be able to access information on a particular feature, including the type of asset, pipe diameter, pipe material and manhole depths.

The position and attributes of NI Water infrastructure shown on the map should be regarded as approximate and should not be relied upon. NI Water does not accept liability for loss or damage to any person or property caused as a result of any inaccuracy in the information. For health and safety reasons it is your responsibility to determine the exact location of NI Water infrastructure, prior to any excavation work being undertaken and it is recommended that hand dug trial holes are used to determine the precise location.
