Ringsend Sludge Stream Expansion Project
Uisce Éireann
Upgrade
Dublin, ROI
The Sludge Stream Expansion Project was procured by Irish Water (Dublin City Council) to provide an increase in the capacity of the existing sludge treatment facilities to treat the additional sludges that were being generated from the increase in load through the Ringsend WwTW, an increase of c.180,000PE.
CAW, as the Works Operator, was employed by Uisce Éireann to deliver the Extended Sludge Plant, which incorporated a new third stream CAMBI THP Sludge Plant.
Project Highlights
Project Scope
The scope of work for this extension included the provision of:
- 3 x additional SAS Drum Thickeners with associated plant;
- 1 x additional sludge thickening centrifuge with associated plant;
- 1 x third stream of CAMBI THP Plant;
- 1 x additional digester tank of 4,500m3 capacity;
- 4 x digester sludge cooling/recirculation systems;
- Associated instrumentation, electrical cabling, SCADA control and MCCs.
The net effect is that the throughput of the existing sludge processing plant was increased by 60% allowing the THP Plant to treat up to 120 tonnes DS/day.
Project overview
The Project was delivered, by CAW, on a design, build, supply, installation and commissioning basis at a capital cost of €18.993m and was delivered by a Project team, led by a CAW Project Manager, and included CAW Project Engineer(s), Designers, On-Site Manager(s), Supervisory Staff and Commissioning Engineers.
A detailed programme, using Primavera P3e, was developed to enable sufficient information to be available to manage the design, procurement, construction and commissioning of the Plant.
A Project Plan was compiled and implemented which comprised a Project Summary, Health and Safety Plan, Environment Plan and a Quality Management Plan.
The Project was successfully commissioned and completed in April 2010, was delivered on time and within budget and has significantly improved the capacity of the Works to process the additional sludge resulting from the increase in load to the main process streams
