Doran Consulting were appointed by main
contractor EPS as Civil, Structural, Hydraulic, Process and MEICA Designers for
the Design Build Operate Contract to provide four new Wastewater Treatment
Plants in West Cork with associated sewerage upgrades.
The Cork Mid-West Bundle Sewerage Scheme provided four new Wastewater Treatment Works at a cost of €27 million to increase the capacity of existing plants to cater for present and future population equivalents of 600PE at Dripsey and 1600PE at Coachford and provide new capacity population equivalents of 2600PE at Ballymakeera and 1600PE at Innishannon as well as upgrading the sewerage networks. These areas had been previously served by overloaded and outdated wastewater treatment infrastructure which required new wastewater treatment plants and network upgrades that will enhance water quality by ending the discharge of poorly treated waste in these areas.
Doran Consulting were commissioned by EPS Group Ltd, who delivered the works on behalf of Irish Water, to provide complete design packages for each of the works as follows:
BALLYVOURNEY/ BALLYMAKEERA WwTW
New 2,600PE activated sludge wastewater treatment plant serving both Ballyvourney and Ballymakeera, demolition of the existing septic tank, new outfall pipe and upgrade works to the existing pumping station and new rising main.
COACHFORD WwTW
New 1,600PE wastewater treatment plant at Coachford involved the demolition of the existing septic tank on the site and replacement with a new Rotating Biological Contactor (RBC) plant, upgrades to the sewer network and construction of a new outfall pipeline.
DRIPSEY WwTW
New 1,200PE wastewater treatment plant to serve Dripsey and the surrounding local area, including demolition of the existing wastewater treatment works and replacement with a new Rotating Biological Contactor (RBC) plant, rehabilitation and replacement of gravity mains as well as a new outfall.
