Kinvara Wastewater Treatment Plant

Wastewater Project

This €3.5 million project was needed to build a new wastewater treatment plant in order to stop untreated wastewater being discharged directly into the sea at Kinvara.

The seaside town of Kinvara is located on the south shoreline of Galway Bay. The town is a very popular summer destination for day-trippers and holidaymakers who enjoy the active harbour, a number of restaurants, bars, B&Bs and hotels.

Kinvara was one of 44 towns in Ireland where untreated wastewater was discharged directly into the sea as there was no wastewater treatment facilities for the town. The EPA issued a Waste Water Discharge Licence which required the existing discharge of untreated wastewater to be discontinued and a new wastewater treatment plant to be constructed for Kinvara. With a growing local population, a new wastewater treatment plant was essential for Kinvara Town and it's surrounding areas to allow for seasonal/future population growth and further commercial development.
