Core Refusal Reason
The site's soil conditions are unsuitable for the safe attenuation of domestic wastewater effluent, posing a significant risk to public health and the local public water supply.
Decision Maker's Conclusion
- The Planning Authority determined that the site's soil is incapable of appropriately attenuating effluents due to shallow unsaturated soil depth and a high water table.
- The proposed wastewater treatment system fails to comply with the EPA (2021) Code of Practice, as evidenced by subsurface test holes being submerged or collapsed during inspection.
- The development is considered prejudicial to public health, particularly as the site is located within the Source Inner (SI) Protection Area of the Castlerea Public Water Supply.
