Project Overview

The Regional Biosolids Storage Facility is a new strategic project, forming part of Irish Water’s plan to upgrade and improve the wastewater treatment network in greater Dublin.

Biosolids, a by-product of the wastewater treatment process, are a nutrient-rich, organic product used as fertiliser and a soil conditioner in agriculture. They are mainly used in crops produced for animal feed or energy production.

The project aligns with Irish Water’s National Wastewater Sludge Management Plan which sets out a standardised long-term approach to manging the outputs of the wastewater treatment process.

The Regional Biosolids Storage Facility (RBSF) project will involve a comprehensive site assessment and selection process beginning with a study area that includes Dublin City and County and parts of Meath, Kildare and Wicklow.

A proposed site for the new storage facility will be included in the planning application to An Bord Pleanála for the Ringsend Wastewater Treatment Plant Upgrade in late 2017. Separately, the application will include a new additional regional treatment facility in north Dublin (Greater Dublin Drainage project) in early 2018. The applications will be made under the Planning and Development (Strategic Infrastructure) Act 2006.

The Stage 1 Report, Site Selection Methodology, has been published and a four week consultation is open from 2 February 2017 to 2 March 2017.

Project Need and Benefits

Greater Dublin is growing!

The population of the Greater Dublin Area is forecasted to exceed 2 million for the first time by 2031. In turn, the demand for wastewater treatment within greater Dublin is expected to grow by approximately 40% by the year 2050. Water and wastewater treatment are a key part of the primary infrastructure network necessary to underpin residential and commercial development. This will result in a proportional increase in the associated production of biosolids.

It is planned that a new Regional Biosolids Storage Facility will serve greater Dublin and its population for the next 25 years and will safeguard public health, protect our environment and facilitate development in this growing region. The new regional facility will lead to greater efficiencies and more effective management of the wastewater network over the longer term.

Benefits of the project include:

  • A single regional biosolids storage facility, located closer to where biosolids are produced and in proximity to transport networks rather than numerous smaller facilities spread across several communities. 
  • A storage facility closer to greater Dublin’s wastewater treatment plants where biosolids will continue to be produced into the future.
  • The area required for one regional facility will require less space than multiple units ensuring environmental sustainability.
  • One regional facility, close to transport routes, will have a lower traffic impact on the region’s communities than several small / local storage facilities. This is because fewer trucks will collect the biosolids to distribute them across Leinster, rather than many small vehicles making regular collections to local storage centres.
  • One small team will operate and manage a regional storage facility to a continuous standard thus enabling consistent high quality.
