Founded in 1979

A well established company

In 1979, using a local gravel reserve for raw materials, operations to manufacture a range of general precast concrete products began near Tullamore, Ireland. In 1983, the company commenced manufacturing precast concrete tanks. Throughout the 1980's, the company expanded it’s factory and invested in plant and moulds to increase production capacity.

Molloy Precast premises and factory in Tullamore, Co. Offaly


New environmental standards in the 1990’s required on site effluent treatment systems to improve the quality of water discharged by incorporating secondary and tertiary treatment technologies. Subsequently, Molloy acquired the wastewater treatment business of Atlas Oil Environmental and developed the most comprehensive offering of wastewater treatment plants in the marketplace for both single houses and large developments.

In 2006, to facilitate expansion, the company purchased a new site and now operates from a modern factory and offices at Coleraine, Clara Road, Tullamore, Co. Offaly, Ireland. This location features an extensive courtyard where fully operational models of the company's products are on display. It also features Ireland’s most comprehensive percolation demonstration facility to indicate to homeowners and construction professionals how to build percolation areas.

Today, the company engages in research and development with world leading universities, and has come to be recognised as a leader in the manufacture of wastewater treatment plants and sewage pumping stations for the domestic, commercial and municipal sectors in Ireland.
