PPS 11: Planning and Waste Management
Policy WM 2: Waste Water Treatment Facilities
7.11 Waste water is not controlled waste and therefore the WMS and WMPs do not apply to proposals for waste water treatment works (WWTWs) and related facilities. In such cases the applicant must demonstrate that there is a need for the facility and that the proposal is the BPEO. Proposals for WWTWs are normally Crown development. Whilst the Planning (Northern Ireland) Order 1991 does not apply to Crown development, normal practice is to follow the planning application procedure as much as is possible and to apply policy in exactly the same way as in the case of planning applications. The Planning (Environmental Impact Assessment) NI 1999 Regulations apply to Crown development. Due to their nature and scale many WWTWs have the potential to have a significant impact on the environment and on the amenity of local communities. As a result they are often located in the countryside away from residential development. Consent for Crown development will be refused if the impact would be unacceptable. Odours, quality of discharge and visual impact are important considerations.
