Limerick Gasworks Remediation

Cleaning up the former Gasworks site in Limerick.

Background to the project

Gas Networks Ireland is working to clean up the site of the former Gasworks on the Dock Road in Limerick. 

The clean-up or remediation works consist of two phased contracts, namely Phase 1 ‘Pump & Treat’ followed by Phase 2 ‘Soil Stabilisation’. The intention is to remediate as much soil on-site as possible with minimal waste material taken off site.

More information on these works brochure is available in our project brochure at the following link: Limerick Gasworks Remediation Brochure 

A licence to clean up the site has been obtained from the Environmental Protection Agency and planning permission was granted from Limerick City Council.

On completion of the project, the site will be developed in accordance with the Limerick City Development Plan. While there are currently no plans for the site, the aim of the works is to clean up the site and facilitate the reintegration of the site within the city environment.

Progress to Date

The Phase 1 ‘Pump & Treat’ works were successfully completed in late 2017 and during 2018 enabling works were undertaken to prepare for the 2019 Phase 2 ‘Soil Stabilisation’ contract.

What's Happening Now

Works on Phase 2 ‘Soil Stabilisation’ commenced last August by our contractor, Murphy International Limited, and are expected to be completed by April this year.

The soil stabilisation works are carried out in the following way:

  • The soil within the site is excavated up to a depth of approximately 3 metres and any remaining underground tanks removed;
  • The soil is screened and concrete crushed and then binders are mixed into the excavated soil/crushed material producing a stabilised material;
  • This stabilised material is then carefully backfilled in the site, resulting in a solid finish at similar levels to the site prior to this stage.

These works are being carefully supervised, with noise, vibration and dust monitoring, to ensure that disturbance or impact from the works is minimised and carried out in compliance with planning and licencing requirements.

The use of an odour control system, in the form of a mist, may be noticeable along the perimeter of the site over the next few months, January to April 2020.  This mist is water-based and uses an odour neutralising additive, which is biodegradable, to assist in minimising odours. Neither this mist, nor any odours associated with the site, are harmful to health.

We will continue to keep local residents and businesses updated as the works progress.

What Happens Next?

Soil stabilisation works are expected to be completed in April 2020.

Once the Limerick Gasworks site has been remediated, it will be suitable for development in accordance with the Limerick City Development Plan.

While there are currently no plans for its future use, this project will complete the cleanup of the site and facilitate its reintegration to Limerick City.
