The Drainage Operations Section is based at Deansrath Depot, Clondalkin.
This Section is responsible for the South Dublin County Council Drainage System which comprises approximately 1,200 km of foul and surface water public sewers.
The drainage system in most modern housing estates, comprise two separate systems - a foul drainage system and a surface water system. The foul drainage system is designed to collect wastewater not only from toilets but also from wash-hand basins, sinks, washing machines and dishwashers. All this effluent is transported via piped systems to the wastewater treatment plant at Ringsend.
On the other hand, the surface water system is designed to channel stormwater (rainwater) to the nearest suitable river. Rivers and streams are natural surface water channels.
The drainage system in some older estates have a single system, 'combined sewerage system', where foul drainage and surface water enter the same pipes and everything is transported through the trunk piped system to the wastewater treatment plant at Ringsend.
The Council is also an active participant in the Greater Dublin Strategic Drainage Study (GDSDS). The GDSDS was set up in 2001 to analyse the existing drainage system in the Greater Dublin Area and to make recommendations on future drainage practices. Dublin City Council (DCC) is the Contracting Authority acting on behalf of Fingal, South Dublin, Dun Laoghaire Rathdown, Meath, Kildare and Wicklow County Councils. The GDSDS recommendations (Insert link) were presented in 2005 and have been adopted by South Dublin County Council.
