William and Michael Kiely Ltd

In the late 1960's William & Michael Kiely began manufacturing  precast concrete septic tanks.  Subsequently they established W & M Kiely Ltd which is now one of the most modern manufacturing facilities in the world. 

Please visit our website www.wmkiely.ie for full details on all our products. Our precast concrete tanks range in sizes from 150 to 4000 gallons and are suitable for water & effluent storage, grease traps and septic tanks.  Our double chamber septic tanks are EN 12566-1 Certified.  All tanks for farm use, 1000 - 4000 gallon, have heavy duty covers and are fully grant approved.

We began manufacturing slatted flooring for Cattle, sheep and pigs in 1990.  The Cattle & Tractor slats range in sizes from 7'6" to 16'6".  The sheep and pigs slats can be made to order depending on the size you require, from 3' up to a maximum of 9'6" long.  All slats are manufactured to the highest specifications and are grant approved.

The Kiely BioKast wastewater treatment system was designed and patented by William Kiely Snr.  It is EN 12566-3 Certified. It is a large capacity reinforced concrete tank and proves to be one of the most durable and reliable systems on the market.  All maintenance of BioKast systems is carried out directly by our staff.


We also manufacture precast Cubicle Beds, Oil Interceptor Tanks, Rainwater Harvesting Systems & Precast Insulated Walls.

We are located about 9 miles outside of Cork city.  


Leave the city on the Mallow road, and take the slip road for Blarney. As you go through Blarney (there is a small by-pass that avoids the square) you will come to a T-junction.  Turn right and keep on the main road heading toward the Tower.  One mile out that road you will see a sign for Donoughmore, take this right.  Go up that road for 4 miles, and you will come to a cross roads, turn right here.  This will take you to Courtback, when you get here, you will see and old shop, and we are 100 yards past this onthe left.
