Main Lift Pumping Station Upgrade
Modernising and upgrading the largest pumping station in Ireland to improve performance and improve energy efficiency
Irish Water, working in partnership with Dublin City Council, has commenced essential upgrades to the Main Lift wastewater pumping station at Ringsend, Dublin. The Main Lift Pumping Station is the largest wastewater pumping station in Ireland. Approximately 60% of the wastewater that is treated at Ringsend Wastewater Treatment Plant passes through this pump station every day. There are six pumps operating at this pumping station. They pump unscreened wastewater to a high level collection chamber at the pumping station. The wastewater then gravitates to Ringsend Wastewater Treatment Plant through twin reinforced concrete siphon pipelines.
This project will upgrade and modernise several elements of the process at the plant. This includes installing six new pumps, as well as installing two new transformers and refurbishing the pump station roof which will lead to energy efficiency improvements at the plant. EPS Group Limited is delivering this project on behalf of Irish Water.
What is involved?
- Installing installing six new pumps (630kW 3.3KV pumps with a flow of 3300l/sec each)
- Installing associated pipework, switchgear, control panels and ancillary equipment
- Installing two new transformers
- Refurbishing the pump station roof
- This upgrade will lead to estimated annual savings of 2,799,146 kWh/year or over 2,182 tonnes of carbon, which equates to annual savings of over €335,000 for the business
- Modernise and improve the performance of the pumping station
- Reduce energy consumption and carbon emissions
- Reduce the risk of failure at the site and subsequent flooding in Dublin
- The first two pumps were delivered to site in December 2019 with installation commencing shortly
- Works are ongoing in preparation for this installation including removal of pump 6, installation of new invert siphon and associated works
- The installation of the second pump is expected to commence in March 2020 which will further reduce the risk of failure at this site
