Meencrumlin Water Treatment Works, Co. Donegal

MDE are proud to have worked in partnership with AECOM Ireland, Siac Civil Engineering and Irish water to deliver the new water treatment plant in Meencrumlin, Co. Donegal.  The project consisted of upgrading and expansion of an existing Water Treatment Plant from 5,500m3/day treatment capacity to 11,000m3/day treatment capacity.

The upgrading and expansion of the Main Treatment Plant involved the electrical services and instrumentation associated with: New Chemical Dosing System; Raw Water Flow Control and Flash Mixer/Flocculation Units; New Sedimentation Tanks and upgrading of existing Sedimentation Tanks using Inclined Tube Settlers; New Filters and upgrading of existing Filters and new pH Correction and Chlorination Systems.  The project also included a new treatment facility for wastes arising from the treatment plant.  This involved separating the filter backwash water from sludge bleed water, sludge thickening and final dewatering of the sludge using a plate press system.

Carnmoney Water Treatment Works

The installation of electrical equipment and systems for water management is a complex and skilled area. We have developed considerable expertise in installing the electrical services,  instrumentation and technology required in a modern water treatment works.

MDE were assigned as electrical contractor for the Carnmoney Water Treatment Works to design, certify, install, and to test and commission all electrical, instrumentation and system integration plant and services.

Our contract also required that we decommission and disconnect existing electrical equipment, instrumentation and services which were redundant, make them safe, and safely remove them from the site, disposing of them correctly and subsequent making good.

Works included process cable design, lighting design, fibre network installation, Profibus cable installation and termination, containment installations, distribution and wiring systems; general purpose socket outlet and fixed power services.

We installed internal and external lighting including, emergency lighting systems, and intruder detection and alarm systems. We also installed the telephone system, with associated bonding, earthing and testing.

We were proud to be associated with Carnmoney Water Treatment Works, the largest in Northern Ireland. These upgrade works will greatly improve the existing facilities allowing for development and growth well into the 21st century.

Ballinrees Water Treatment Works

We carried out electrical installation works at both Ballinrees and Castor Bay Water Treatment Works, two sister schemes that we completed concurrently.

These were complex and challenging installations and benefited significantly from the skills of our expert team. Ballinrees is one of the Project Alpha Water Treatment PPP schemes for Northern Ireland Water Service established following the launch of their upgrade of four major existing water treatment facilities in the region.

The two schemes are also part of the first UK PPP project to address the supply of potable water to homes. The existing water treatment works at Ballinrees were upgraded to a new, fully refurbished 30Ml/day facility with extended treatment operations. We carried out contract works on an existing live site coupled with complete building services installation.
