Where it all Began…

Depawater Ltd have been in business for over 15 years specialising in domestic Wastewater Treatment Solutions. Being a family-based business in Co. Armagh, we take a lot of inspiration from Tricel Killarney, a family-based business in Killarney, Co. Kerry.  We like to emulate the family ethos displayed by Tricel Killarney where Tricel products originated under the hard work of Con and Anne Stack and their Family in 1973. Since the Tricel brand was first established in Ireland, it has exploded and today we see the Tricel brand all throughout Ireland but also in France, Germany, USA, Middle-East and North Africa.

Depawater’s family orientated culture promotes a friendly workplace setting for all our employees. Having started out from small beginnings, Depawater is now a Small Medium Enterprise (SME) that is continuing to grow and expand year on year. With multiple vehicles on the road for all business activities Depawater are continually striving to provide all the necessary services you as a homeowner would need to install a septic/wastewater treatment tank for your home.

A special Tribute to…

Depawater annually sponsor the underage Tournament held in the local community in honour of two very special people who where from the area, John Joe Toner and Thomas McLaughlin.  This Tournament, supported by Depawater, sees the local Shamrock Gaels U11.5 and U9.5 teams play against many visiting teams, culminating in a smashing sense of community spirit and pride that we are able to pay tribute to these two very special people.

John Joe Toner

“John Joe Toner was an 11 year old boy from Clady whose life was sadly cut short due to illness. John Joe loved Gaelic football, he was one of the finest underage players I have ever witnessed. His passion for football was evident through his enthusiasm on the football field, he was an exceptional talent! God only knows the heights he would have reached, had he been given the chance.”

The annual John Joe Toner memorial tournament is our tribute and remembrance to his exceptional talent, whilst also inspiring today’s youth to participate in playing a sport loved so much, by so many, just like John Joe. 


“Thomas McLaughlin died suddenly in a tragic accident at his home in Clady in 2005. Tommy was a hugely dedicated underage football coach and mentor. Originally from Donegal, Tommy moved to Newtownhamilton where he established and ran their underage football teams. His charismatic leadership brought him much success which did not go unnoticed as he was part of the Armagh minor management team in 1987.”

Our annual Thomas Mc Laughlin cup is a tribute to Tommy, an inspiring example of dedication, kindness and friendship brought together through sport. His legacy remains today and can be seen in his grandchildren, who proudly take to the field wearing the colours of the Shamrock Gaels.
