Carrigrennan WWTW - Carrigrennan Wastewater Treatment Works Upgrade - Consultant Contract Planning Stage
Carrigrennan WWTP (Wastewater Treatment Plant) is located at Little Island, Co. Cork. The plant treats wastewater from Cork City and surrounding areas in the County.
The plant was commissioned in 2004 with a design organic load capacity of 413 000 population equivalent (p.e.).
The plant was designed to ensure compliance with the Urban Wastewater Directive. It provides primary and secondary treatment. Secondary treatment is achieved by means of a cyclical activated sludge system which is
carried out in Sequence Batch Reactors.
Treated wastewater from the plant is discharged through a 500 m long outfall pipe to Cork Harbour at Lough Mahon.
The design of the existing plant did not include for nutrient removal or disinfection.
Since the plant was commissioned the upper harbour, was designated a sensitive area under the Urban Wastewater Treatment (Amendment) Regulations 2004 (SI 440/2004).
Current discharges from the plant do not comply with these regulations.
Furthermore, there are several shellfish waters designated within Cork Harbour. Discharges from the proposed upgraded plant should take these waters into account.
Cork City Council now requires a consultant to identify what works are necessary to ensure that discharges from Carrigrennan WWTP comply with:
- Environmental Protection Agency Wastewater Discharge Licence D0033-01
- SI 440/2004 and
- SI 268/2006 European Communities (Quality of Shellfish Waters) Regulations 2006
It should be noted that Carrigrennan WWTP was procured using a Design, Build and Operate (DBO) approach. The successful contractor was a consortium of five companies.
This Contractor is currently in year 8 of a 20 year operate contract.
Cork City Council now requires the services of a competent Consultant, with experience of major civil engineering works in the wastewater field, for the following stage:
