Septic tank decommissioned; new wastewater treatment system and percolation area installed

Morgan McCaffrey and Lisa Duignan have applied for retention permission to upgrade the wastewater system at their four‑bedroom house on Knockanroe in Ballinamore, Co Leitrim. The proposal involves decommissioning the existing septic tank and installing a new wastewater treatment system that incorporates a percolation area. The works also include alterations to the site layout that had previously been approved under planning reference 21/218.

The site covers 0.413 hectares and fronts a regional road. The dwelling itself has 245.26 m² of gross floor space, accommodates up to six residents and contains four bedrooms. A site assessment report, prepared by Michael Fitzpatrick Architects and Rosie Carson, found the soil to have moderate drainage characteristics and groundwater vulnerability rated R1, which is considered acceptable for the proposed treatment system.

The application is currently incomplete and no decision has yet been issued by Leitrim County Council. The council’s planning file indicates that the retention permission is sought for the decommissioning of the septic tank and the installation of the new wastewater treatment system and percolation area. The council has not yet confirmed whether the application will be approved or what the timeline for completion might be.

The proposed system would replace the old septic tank with a more modern treatment solution that is designed to meet current environmental standards. The percolation area is intended to allow treated effluent to percolate into the ground, thereby reducing the risk of contamination to the surrounding environment. The layout changes to the site, which had been previously approved, are expected to accommodate the new system and ensure that the property remains compliant with local planning regulations.

Residents and local authorities will need to wait for the council’s decision before any construction can commence. The council’s planning portal lists the application as incomplete, and no further information has been released regarding the status of the retention permission.
