Drainage Catchment Area Surveys

Project Overview


Irish Water Cork County Council

Project Summary

Precision Group were contracted by Irish Water to carry out one of the largest drainage catchment area surveys to take place within Ireland.

The survey area covered the Cork City drainage catchments from South of the river Lee including Centre Island and North of the river Lee, Little Island as far as the Tramore area.

Cork is Ireland’s most southerly city. Built on and around the River Lee, which splits into two channels at the western end of the city then converges again at the eastern end of the city centre. The commercial hub of the city centre is located on Centre island which developed between both channels of the river. The northern channel of the river is tidal as far as the western end of the centre island near the Waterworks. The southern channel is tidal as far as a weir adjacent to UCC.

On both sides of the river, the catchment rises away towards the suburban areas. The north side of the Lee in particular is extremely steep. The topography, old city layout and fast growing very busy European City environment all added challenges to the delivery of this large project.


The key drivers for this Project included :

  • Combined Sewer Overflow (CSO) performance, locations and condition
  • Wastewater Discharge Licence Specified Improvement Programme network issues
  • Network surcharging and flooding
  • Development growth pressure
  • Operational deficiencies (including significant infiltration into parts of the network)
  • The Precision Group’s experienced engineers and state-of-the-art equipment allowed the team to complete a robust drainage area infrastructure survey delivered within budget and set time-frames
