Selected Water Sector Reference Project

We work across the Irish and UK municipal and industrial sectors with blue-chip clients in the utilities, pharmaceutical, food, drinks and medical industries.

Leading project of international significance:

Centocor Wastewater Treatment Plant Design, Build & Operate

The contract consisted of design build & operate of a wastewater treatment plant catering for domestic & manufacturing wastewater flows.

The works were carried out on a live pharmaceutical site in Cork. The plant had the equivalent of size of BOD is 15,000 PE, & a final quality of 5 BOD5/5 TSS/15 tot N/1 PO4-P (inmg/l).

Plant inlet comprised balancing tanks, full pH correction system & temperature control facility, activated sludge reactors, MBR plant, carbon & nutrient dosing stations, sludge thickening, holding & chamber press installation with sludge cake stabilisation.
