Featured Project: Sorensen Civil Engineering

30 Aug 2016

Sorensen Civil Engineering Ltd completed the design and build of the new Waste Water Treatment plant in Carrigtohill in June of this year, with a value of €9.6 million.

It provides for a 30,000 PE (Population Equivalent) loading with future increases to 60,000PE. A provision for storm holding tanks in excess of 1,500m3 is also included. The overall volume of the water retaining RC structures will be in excess of 9,000m3. A steel frame cladded structure of approx. 1,200m2 will contain the inlet and dewatering works. Following detailed geotechnical design, 30,000m3 of stone was imported to achieve a viable formation level for the various structures. Ground surcharging was required to increase the bearing capacity of the ground prior to construction.

In addition to the main structure, the following items form the main elements of the works:


• The construction of 140m2 admin/control building complete with laboratory and conference facilities
• Construction of 2 no. outlying pump stations and storm holding tanks.
• 12,000 m3 dredging for the installation of the 1,295m long, 710mm diameter, HDPE marine outfall pipe and diffuser to the Slatty waters.
• Over 10,500m3 of RC water retaining structures.
