Title: sewage-treatment plant construction work
Quantity or scope:
It is required to upgrade and expand the existing Lower Liffey Valley Sewerage Scheme wastewater treatment plant (WWTP), located in Leixlip, Co. Kildare, from 80 000 PE capacity to 150 000 PE. The WWTP expansion is required to accommodate predicted future increases in waste water flows up to a population equivalent of 150 000, from an expanding domestic, industrial and commercial population. The proposed WWTP expansion will provide secondary and tertiary treatment with nutrient removal. There will be staged completion requirements for the upgraded works.Leixlip is a satellite town of Dublin, close to the M4, in the County of Kildare, approximately 10km, to the west of Dublin. The existing WWTP also serves the towns of Celbridge, Maynooth, Kilcock and Straffan.The existing WWTP near St. Catherines Park, Leixlip, receives industrial and domestic effluent and currently has a total treatment capacity for a PE of 80 000. Currently, there are two main effluent streams flowing into the WWTP:— "Main stream" – taking loading to the works from general catchment; and— Intel Ireland Ltd. Treatment Stream – a dedicated treatment stream designed to accommodate the hydraulic and biological loadings from Intel Ireland Ltd and also takes a contribution from the main stream.The WWTP is located to the South-East of the town and the final effluent is discharged via an outfall to the River Liffey at Leixlip. The River Liffey is designated as a Natural Heritage Area (NHA).The Sludge Management Plan (SMP) for County Kildare (2000) recommended that Leixlip be developed as a satellite site, with de-watered sludge being transported by road to the Osberstown sludge hub centre for final treatment. The WWTP currently digests sludge generated on-site and also accepts liquid sludge from a number of small treatment works located in the northern part of the county.Investigations have been carried out into the potential use of the existing WWTP tanks, incorporating additional technology, to accommodate the extra PE. This has shown that there is the potential to optimise the use of the existing process units, and accommodate the new PE of 150 000. The development will be located within both County Fingal and County Kildare, and include modification to the existing process units, and provision of a new administration control building and covered storage balance tank and additional process units as required to suit the Contractor's design.The contract will include operation and maintenance of the existing wastewater treatment plant during the design-build of the works. The contract will also require an extended process proving period, of one year, where the Works are operated and maintained by the contractor. The contract will have staged completion requirements.The works may involve the execution of additional and repetition of similar works and services.
