In 2004 TOBIN Consulting Engineers were appointed to the position of Client’s Representative for Stage 5 of the Leixlip Water Treatment Plant on behalf of our client Fingal County Council. TOBIN’s remit was to cover all stages of design, planning, contract documents, procurement, supervision of construction and commissioning. The capital cost of this project amounted to €30 million and accounted for the construction of a state of the art ‘stand-alone’ facility which was delivered as a Design and Build project through a Joint Venture between AECOM and SIAC Construction Ltd.
This new facility, measuring over 4,000m2 in area, houses all of the main treatment units, chemical storage and dosing facilities, ancillary plant rooms, a water quality laboratory, electrical power distribution and control rooms, along with a SCADA room, from where the plant is controlled and its performance monitored. The facility is also self serving and houses an impressive amount of welfare facilities for the operational team including a canteen and showering/changing facilities.
This stand alone facility was constructed adjacent to an existing water treatment works. The total capacity of the two facilities combined now serves up to one third of the demand in the Greater Dublin Region, supplying North Dublin City and County as well as parts of South County Dublin and Kildare. TOBIN’s outline design increased the guaranteed safe yield of the plant from 148Ml/day to 215Ml/day and in doing so, made it the second largest water treatment works in the country. The additional capacity provided by this project is vital in meeting the current water demand within the supply area. Applying a forward thinking and proactive approach, we pushed the boundaries on future-proofing the design as much as possible. In addition to the increase in safe yield, the main building was designed to ensure a long design life with minimal necessity for significant maintenance to the fabric or structure, all with a view of having a design life of not less than 50 years.
As a result of this pragmatic approach, and on the back of a very strong working relationship between TOBIN and our client, the Leixlip plant now has the capacity to meet substantial future development needs. This is a key point to note, considering the additional housing that is due to come on board in the Dublin region over the coming years.
