Collooney & Ballymote Wastewater Treatment Plants

At a Glance

The existing waste water treatment plants at Collooney and Ballymote, were substandard and had no storm water storage capacity. A €9.9 million scheme to upgrade the plants and improve the quality of the effluent leaving the plants was awarded to Veolia. Veolia’s Director, Joe Higgins, had pledged that the company would ensure the State got value for money.

The access equipment had been originally specified in galvanized steel, but due to the pledge given by Veolia’s director the Contracts Manager was keen to look at alternatives.

Relinea provided a competitive proposal to the steel system, which had the added advantage of a 50 year design life, as well as significantly reduced installation costs. This was a win win for Veolia and they awarded Relinea the contract to design and supply all access equipment and hatches.

We were required to develop the design for the platforms prior to the work commencing, as Veolia were endeavouring to install main structural steels in parallel with our equipment. Working with the Veolia team, our inhouse GRP designers developed a system that had flexibility to allow for changes on site to match the site requirements.


Our ability to provide full 3D drawings, backed up with full calculations and anchor specification ensured the equipment was supplied prefabricated and could be just dropped into position. Some remedial work was required on site but due to our design and the flexibility of GRP these issues were easily solved.

The client praised our professional approach and was pleasantly surprised how easily the equipment could be installed.
