The focus of the EU Urban River LIFE Project in Dún Laoghaire Rathdown will be the Shanganagh River Catchment. This Catchment contains three tributaries which join at Commons Road becoming the Shanganagh River which makes its way to sea just south of Killiney Beach.
The Tributaries are:
- Carrickmines River (drains Ballyogan,Carrickmines, Glenamuck, Foxrock, Leopardstown Racecourse) has Moderate Ecological Status
- Cabinteely Stream (drains the Park Estate, Cabinteely Village and Park) has Moderate Ecological Status
- Loughlinstown Stream (drains Kilternan, Ballychorus Rd) has Good Ecological Status
The River Basin Management Plan 2018-2021 prepared by the Dept of Housing, Planning and Local Government requires dlrcc to improve the status of the Carrickmines River and the Cabinteely Stream to Good Ecological Status. This document is Ireland's plan to comply with the Water Framework Directive second round.
The environmental pressures on these streams are the result of the suburban environment through which they flow.
1. Sewer OverFlows
2. Domestic Misconnections -the primary pressure.
The discovery and removal of domestic misconnections is an extremely labour intensive and time consuming process with approximately 1 in 12 homes misconnected. Using the latest methods in GIS technology, the EU Urban River LIFE Project will explore methods to find misconnections in a much more efficient fashion, thereby speeding the removal of domestic from our streams.
In the Shanganagh Catchment the EU Urban River LIFE Project Team will:
- Raise public awareness of the issues effecting water quality in the catchment through public meetings and school visits
- Create a GIS model of the Shanganagh Catchment
- Use this model to strategically direct misconnection surveys to where they will have optimum impact.
- 5000 misconnection surveys will be carried out in the catchment in 3.5 years.
- Provide insights and learnings that will be used for the other catchments in the County.
This project will enable Dún Laoghaire Rathdown to comply with the Water Framework Directive's requirement to have good ecological status for the Shanganagh Cathment. It also provides a welcome opportunity to work alongside our neighbours in South Dublin County Council.
