Wastewater System Capacity Information

Council Areas (February 2022)

Disclaimer:

The wastewater system capacity information provided by Council area for (WwTW >250 population equivalent) in this document is subject to change. This may happen as a result of more detailed information becoming available through on-site investigations or ongoing Drainage Area Studies.  NI Water should always be contacted directly on water and wastewater capacity issues by Council and Developer.

NI Water is committed to working with developers to consider ways of accommodating development wherever possible.  The phasing of development is of high importance going forwards due to the historic and prolonged under investment in wastewater infrastructure across Northern Ireland.

Developers should always use the pre-development enquiry (PDE) process. PDEs are valid for an 18 month period from issue. Should formal approval to make connections to the public water and sewerage networks not have been granted by NI Water within this timescale, a further PDE will require to be submitted to ensure that capacity currently identified as being available to serve this proposal, still exists.

*All investments/upgrades detailed for completion during PC21 are subject to all statutory approvals being in place, land acquisition (where appropriate), and the availability of funding.  Due to emerging issues, it is also possible that some re-prioritisation of the investment programme may take place and would be agreed with NI Water’s regulators.
