Refused

Core Refusal Reason

The site is unsuitable for the safe disposal of domestic effluent due to poor soil drainage and high water table levels, posing a significant risk to public health and the environment.

Decision Maker's Conclusion

  • The site exhibits extremely poor percolation characteristics, with evidence of saturated ground, surface water ponding, and subsurface test holes being found submerged during inspection.
  • The proposed wastewater treatment system fails to meet the 2021 EPA Code of Practice requirements, specifically the inability to maintain the minimum 0.5m of unsaturated soil required for effluent attenuation.
  • The development is considered prejudicial to public health and would set an undesirable precedent for development on sites with similar drainage constraints in the 'Remaining Rural Area' zone.
