Core Refusal Reason
The proposed domestic wastewater treatment system is non-compliant with the EPA Code of Practice due to failed percolation tests and technical design deficiencies in the sand polishing filter.
Decision Maker's Conclusion
- The site failed surface percolation tests at the pre-soak stage, indicating soil conditions are unsuitable for the proposed drip dispersal system which requires a percolation value of less than 120.
- The sand polishing filter design is technically flawed as it omits the required basal gravel layer and fails to provide the mandatory 0.9m depth of unsaturated subsoil.
- The proposed development poses a risk to public health and is contrary to the proper planning and sustainable development of the area due to inadequate wastewater management.

Decision Document Summary
This application sought permission for the renovation and a 112.3sqm extension of a structure at Ballyhealycastle, Kilmore. The local authority refused the proposal primarily because the site's drainage characteristics failed to meet the EPA Code of Practice for domestic wastewater treatment. Specifically, the soil failed initial percolation tests and the technical design of the polishing filter was missing critical components, leading to concerns regarding public health and environmental safety...SOURCE PDFOpen Original
