Policy WWI1 Development Relying on Non-Mains Wastewater Infrastructure
A proposal for new development relying on non mains wastewater infrastructure will only be permitted where the applicant has demonstrated, through the submission of sufficient information on the means of wastewater treatment and disposal that it will not create or add to a pollution problem.
In those areas identified as having a pollution risk, in exceptional circumstances non-mains wastewater infrastructure will only be permitted where appropriate mitigation measures have been identified.
Justification and Amplification
This policy seeks to ensure that proposals for new development relying on non-mains wastewater infrastructure, either individually or cumulatively, do not increase the risk of pollution. The applicant will therefore be required to provide information to demonstrate to the Council’s satisfaction that the proposed development will not add to or create a pollution problem. Applicants should consider the installation of a package Wastewater Treatment Plant which is considered to be an effective system in treating sewage and thus reducing the risk of pollution.
Where there are WwTW capacity or network capacity constraints, or where the development is within an area identified as having a pollution risk, the applicant must also submit detailed information on proposed mitigation measures. In some cases, the applicant may be requested to provide a private WwTW or contribute to infrastructure upgrade costs to facilitate their development. This will be required to be agreed with the Council.
The Council will consult with NIEA Water Management Unit and NI Water where appropriate. Applicants will also have to obtain a relevant waste management authorisation from NIEA i.e. discharge consent etc.
