The utility is investing €200 million on a programme of works that will include a new water treatment plant at Vartry, which is to be designed, con- structed and commissioned by Veolia Water Ireland. "The upgrade of the Vartry water supply scheme has been a priority for Irish Water since the utility took over the responsibil- ity for water services in 2014," Geoff O'Sullivan, project man- ager with Irish Water, said. "The scheme has had no major upgrade since it was built 150 years ago and is in urgent need of this investment." In the 19th century, the Vartry scheme had put Dublin at the cut- ting edge of water treatment in Europe. To combat the growing danger posed by water-borne dis- eases such as cholera, Dublin Corporation devised a scheme to supply residents to the south of the Irish capital with what a con- temporary observer described as the River Vartry's "peculiarly soŽ pure water". The move had been made following a report in 1860 – when water supply agreements with the canals were due for renewal – that described the existing supply as "bad". Creating a system to utilise the River Vartry, though, was a tall order – not least because much of the ground and build- ing work had to be carried out using only picks, shovels, horses and carts – but work began in 1862 and, within six years, it was complete. A 1,640Ž-long embankment was constructed to make the main reservoir on the hills at Roundwood, providing a capac- ity of 11.3 billion litres; two dis- tributing reservoirs were also created in the Dublin suburb of Stillorgan, connected to Round- wood via an aqueduct. Perhaps the project's greatest feat was the 6Ž high, 5Ž wide Cal- lowhill tunnel, which runs 4,332 yards (3.96km). The work took from January 1863 to September 1866, with chief engineer Parke Neville saying their task had been complicated by the "hardness of the rock", "irregularities of the stratification and thinness of the layers", as well as "the quantity of water". There were two separate The main reservoir and treatment works at Roundhill were created in the 1860s Bringing historic Vartry up to date • Veolia gets contract for new water treatment plant as Irish Water gives celebrated Vartry supply scheme first major upgrade in 150 years By Robin Hackett FUSAMATIC ™ MULTISEAL TAPPING TEE STACKLOAD OR UNDERCLAMP FOR GAS AND WATER Fusion Group Limited | Chesterfield | Derbyshire | S41 9PZ | England, UK T: +44 (0) 1246 268666 | E: sales@fusiongroup.com | www.fusiongroup.com Multiseal tapping tees deliver security, safety, simplicity and speed at the point of installation • Designed to minimise joint cycle times. • Reduced cutter torque. • Corrosion resistant brass terminal pins. • Corrosion resistant stainless steel cutter blades Sizes Sizes range from d40 – 355mm with 20, 25, 32, 40, 50 and 63mm outlets.
