A Cork-based wastewater treatment business, Ireland Waste Water (IWW), has announced plans to double its staff numbers with the recruitment of 10 workers to its team.

IWW is looking to fill the positions – most of which will be based at its HQ in Cork, in several areas: technical sales, service, administration, finance, project management and general operations.

The recruitment drive is part of the business’s wider expansion plans following several years of steady growth. IWW has reported very strong demand for its newest addition to its product line - Circle 7 – a domestic and commercial water purifying system which, the company claims, is the first of its kind in the world.

Precast concrete wastewater treatment systems


IWW is a privately owned Irish company, founded in Cork by Mary and Niall Mulcahy more than 20 years ago. It designs, manufactures and installs precast concrete wastewater treatment systems, septic tanks, interceptors, grease traps, rainwater harvesting systems.

It also manufactures precast holding tanks for farm effluent, drinking water and so on. The total septic tank market in Ireland is estimated to be worth more than €3 billion.

Mary Mulcahy, co-founder of IWW, said: “We are going to add 10 more people to our fantastic team by the end of the year – and it’s likely we will grow by another 10 in 2020.

"We’ve been lucky to date in that the people who work with us not only have the skills we need, but the work ethos we admire. However, employment levels in Ireland at high at the moment – and this is great, but it does present some challenges for employers.

“Since we launched Circle 7 earlier this year the demand has been phenomenal – people the length and breadth of the country have been getting in touch with us saying they have been looking for a solution just like this but had not been able to find one to date."

"The demand in the West of Ireland has been particularly strong, and while we have been and will continue to service customers all over the country - logistics is definitely a challenge.

"We need to transport huge concrete tanks by the use of cranes and as we are almost at full capacity at the moment, we are looking at other avenues for our distribution network.”
