Limerick Wastewater Treatment Plant Upgrade Project

Wastewater Treatment Plant and Regional Sludge Hub Centre

Project Background

Limerick Wastewater Treatment Plant has been providing wastewater treatment to Limerick City and surrounding areas since the early 2000's.

Uisce Éireann has identified that the plant is becoming overloaded. Upgrades to the wastewater treatment process are required to ensure continued environmental compliance, and to support the growth and development of Limerick City into the future.

The continuation of appropriate wastewater treatment will be vital to protect both human health and the local environment, as population grows and industry continues to expand in Limerick City.

Limerick Wastewater Treatment Plant has also been selected as the preferred location in the Southern Region for the development of a Sludge Hub Centre, accepting sludge imports from smaller plants in Counties Limerick, Clare and Tipperary. This forms part of the National Wastewater Sludge Management Plan which aims to deliver a sustainable and standardised approach for wastewater sludge management.

The existing sludge facility at the plant was last upgraded in 2017 and already treats sludge produced at the plant itself and at smaller plants in Counties Limerick, Clare and Tipperary.
