disconnection of the existing foul and surface water drainage from the existing shared drainage line with No.4 & No.6 Kilruddery Cottages which runs through the site, and the installation of a new independent treatment system and percolation area for No.1 & No.3 Kilruddery Cottages. Existing foul drainage line for No.4 & No.6 Kilruddery Cottages will remain active. Installation of new surface water soakaway to serve No.1 & No.3 Kilruddery Cottages. All associated landscaping, drainage, ancillary site works and services
Core Refusal Reason
The proposal to disconnect from a public/shared drainage network in favor of a private treatment system serving multiple dwellings is contrary to sustainable development policies and specific County Development Plan objectives prohibiting multi-house private treatment plants.
Decision Maker's Conclusion
- The disconnection of dwellings from the public drainage network to install a private system is a retrograde step that undermines the Core Objectives of the County Development Plan regarding sustainable development and groundwater protection.
- The installation of a single private wastewater treatment system to serve two separate dwellings is expressly prohibited by Objective CPO 13.17 of the Wicklow County Development Plan 2022-2028.
- Granting permission would set an undesirable precedent for the proliferation of private effluent treatment systems, which increases the risk of groundwater contamination and is prejudicial to public health.
