Core Refusal Reason
The proposed development was refused due to unsuitable site conditions for wastewater treatment, specifically poor percolation and a high water table, which pose a risk to public health and groundwater quality.
Decision Maker's Conclusion
- Site inspections and visual indicators confirmed poor percolation and a high water table (500mm below ground level), rendering the site unsuitable for the safe discharge of effluent.
- The proposal fails to comply with the EPA Code of Practice 2021 for Domestic Wastewater Treatment Systems, particularly regarding minimum unsaturated soil depth requirements.
- Given the site's location over a regionally important aquifer, the inability to adequately attenuate wastewater would be injurious to public health and contrary to sustainable development.
