Meath Wastewater Treatment Plants Upgrade

Wastewater Project

Upgrades to the wastewater treatment plants in Kells and Trim to improve energy efficiency and reduce carbon emissions.

Irish Water, working in partnership with Meath County Council, is upgrading the wastewater treatment plants in Kells and Trim, Co. Meath. These improvement works are part of a €1.2 million investment to the northeast area, which will upgrade the aeration systems at the plants as part of the energy efficiency programme. 

This project will upgrade and modernise the aeration system at the treatment plants to a more energy efficient system, reducing energy consumption and reduce carbon emissions by 129 tonnes per year. Conway Engineering and Company Ltd is working on behalf of Irish Water to deliver these projects, with the works scheduled to commence in the coming weeks.



  • Modernise and improve wastewater treatment processes at the plants
  • Improve energy efficiency at the plants
  • Reduce energy demands at the plants by up to 115,889 kWh per year
  • Reduce greenhouse gas emissions, which will equate to up a 31.5 tonnes reduction in carbon emissions per year
  • Ensure compliance with Urban Wastewater Treatment Regulations 2001


  • Upgrade the aeration system at the plants, installing a fixed fine bubble diffused aeration system to increase energy efficiency
  • Install of associated brackets, blowers and pipe works and ancillary works
  • Works will be carried out within the footprint of the plants, therefore minimising traffic disruption to residents and businesses in the surrounding area

Energy Efficiency Commitment

Irish Water is implementing a sustainable energy strategy to improve our energy efficiency. These projects are part of Irish Water’s energy efficiency programme which upgrades, replaces and optimises inefficient plants and processes across the country to improve our energy efficiency and reduce carbon emissions.

To date, Irish Water has made significant progress in making our plants and our business more energy efficient. By 2017, water services had achieved a 22.4% improvement in energy efficiency performance, with a corresponding saving of over 51,000 tonnes of carbon.
