Rush Wastewater Collection Network
At present 75% of wastewater generated in Rush discharges untreated into the Irish Sea. Despite the population growth over the last twenty years the wastewater network has remained largely the same. The Rush Wastewater Collection Network scheme aims to cease the discharge of sewage into the Irish Sea by reversing all flows within the catchment and conveying them to the newly built Portrane Wastewater Treatment Plant. This scheme represents an investment of €7.3m by Irish Water.
Portrane, Donabate, Rush and Lusk Wastewater Strategy
The Rush scheme was a key component of an overall strategy developed by Fingal County Council for the Portrane, Donabate, Rush and Lusk areas. This scheme is now being undertaken in partnership with Irish Water. The strategy involved the provision of a single wastewater treatment plant in Portrane to treat the wastewater generated in the four areas. It also included for the provision of a pump station at Whitestown to transfer wastewater from the northside of the Rogerstown Estuary i.e from Rush and Lusk to the Portrane plant.
As a result of this strategy the following infrastructure has been constructed in recent years:
- Portrane WWTP – opened in 2013 with capacity for 65,000 PE
- Long sea outfall from the WWTP – for the discharge of treated effluent to the Irish Sea
- Whitestown Pump station – to pump flows to the WWTP from Rush and Lusk
- Gravity sewer from Lusk to Whitestown – Connection for Lusk to the WWTP
- Donabate Pump station and associated rising mains
- Portrane Pump station and associated rising mains
- Two pipelines across the Rogerstown Estuary – connecting everything north of the Estuary to Portrane.
- Channel Road sewer Rush – Connection for Rush to the WWTP
The next stage of the strategy, the connection of the entire Rush catchment to the WWTP is set to commence construction in mid 2016. This will be an Irish Water Project undertaken in partnership with Fingal County Council. The scheme has already undergone detailed design and the necessary planning consents are in place for the works. South Beach, Rush is one of seven beaches nationally that was rated as ‘poor’ in the recently published EPA Bathing Water Quality Report. The investment in wastewater infrastructure at South Beach, Rush, will provide a new system to collect and transfer wastewater from existing outfalls and overflows to the foreshore and onwards to the new wastewater treatment plant at Portrane which should result in an improved water quality classification for this bathing water.
The Rush scheme will involve the construction of three new pump stations and approximately 6km of associated sewers.
The three pumping stations required are located in the following areas:
- North Beach Pumping Station: adjacent to the Golden Ridge housing development and will serve the north of the town and the Skerries Road. This Pumping station will pump flows to the Channel Road sewer
- East Shore Pumping Station: adjacent to the Martello Tower and will serve the east of the town. This station will pump flows west to the South Shore Pumping station.
- South Shore Pumping Station: located at the beach car park. This station will pump flows into the Channel road sewer.
Negotiations are currently ongoing with landowners to acquire wayleaves and land for the construction of this infrastructure. Given the complexity of the scheme, the suitability of contractors are being assessed. Submissions were submitted for the prequalification (PQQ) on 4th June 2015. These submissions are currently being assessed. Tender documents are being prepared and prequalified contractors will be invited to tender for the construction of the scheme in the coming weeks.
Following the review of the tenders a Contractor will be appointed to undertake the works. The works are currently programmed to commence in Summer 2016 and construction is programmed to be completed in mid 2018.
This scheme represents an investment of €7.3m by Irish Water. The value of the scheme is above the €5.186m threshold and due to this level of investment Irish Water must follow EU procurement rules in line with the Utilities Directive. There are statutory time periods associated with the various steps of the procurement process which are being adhered to.
Founded in July 2013, Irish Water is bringing the water and wastewater services of all 32 Local Authorities together under one national service provider. Irish Water has been taking over the responsibilities from these Local Authorities on a phased basis since January 2014. It will take approximately five years for Irish Water to be fully established, at which point it will be responsible for the operation of public water services including management of national water assets, maintenance of the water system, investment and planning, managing capital projects and customer care and billing. By taking a national approach to managing Ireland’s water and wastewater infrastructure, Irish Water is providing much needed investment in the infrastructure which has been lacking for a number of decades despite the good work of the Local Authorities. This investment is allowing Irish Water to address weaknesses in the water system, including high leakage rates, varying quality standards, and disruptions to supply.
