Core Refusal Reason
The site is unsuitable for the safe disposal of domestic effluent due to poor soil drainage and inadequate site investigation depth in a hydrogeologically sensitive area.
Decision Maker's Conclusion
- The Planning Authority is not satisfied that the site's soil can appropriately attenuate effluents, as all percolation test holes were found to be water-filled during site inspection.
- The trial hole was excavated to an insufficient depth of 2.3m, failing to meet the 3m requirement for a site located within a regionally important aquifer with extreme vulnerability.
- The proposed development fails to comply with the EPA (2021) Code of Practice for Domestic Waste Water Treatment Systems, making it prejudicial to public health and environmental sustainability.

Decision Document Summary
The applicant, Clive Egan, proposed to convert an existing derelict house into a domestic garage and construct a new dwelling house with a wastewater treatment system at Tonlegee Townland, Roscommon. Although the proposal was considered acceptable in principle regarding housing policy, design, and road safety, it was refused due to critical failures in wastewater management. Site inspections revealed that the percolation test holes were submerged and the trial hole depth was insufficient for the...SOURCE PDFOpen Original
