In the late 1960’s William & Michael Kiely began to manufacture pre-cast concrete septic tanks. They soon became the largest manufacturer of septic tanks in the Munster region. The Kiely ‘figure 8’ septic tank and orange trucks were well recognised in the construction industry. In 1980 they established W & M Kiely Ltd. and soon after began to manufacture slatted flooring at the factory in Courtbrack, Blarney, Co. Cork.

Our family business has grown over the years and we now manufacture a range of concrete products including Septic Tanks, BioKast Wastewater Treatment Systems (designed by William Kiely Snr & patented in Ireland & UK), Cattle & Tractor Slats, Pig & Sheep Slats, Beams, Cubicle beds, Effluent & Water Tanks, Grease Traps, Pump Chambers, Rainwater Harvesting Systems, Oil interceptor tanks & Precast Walls.

We take pride in our products and insist on quality and customer service. All our products are certified and grant approved. We supervise every aspect of the business from design, batching our own concrete, testing of products and finally delivering direct to the customer. We offer a full maintenance service for our BioKast sewage treatment systems so you can rest assured that when you buy a Kiely BioKast system we will be there to look after the routine maintenance down the line.

Together with William & Michael, William Jnr & Susan Kiely hope to continue the business well into the future.
