Planning case SD18A0180

CN0082217SD · Irish Water has identified a requirement to provide additional effective storage of 100Ml (100,000m3) at the existing reservoir site at Saggart and associated upgrade works. This is to provide security of supply and resilience by the provision of sufficient storage capacity at the site for operations and transfer of treated water from the complex to strategic service reservoirs in the Greater Dublin Area. A new On-Site Electro Chlorination Plant building (OSEC building) housing a new replacement secondary chlorination plant is also required as the existing chlorination plant has reached the end of its service life. The new OSEC building shall house an ESB substation, chlorination plant and associated equipment, de-chlorination plant, a backup power generator, controls and welfare facilities. The development shall comprise in summary the following works (non-exhaustive list): Section 1 Works: • 100,000m3 effective capacity covered potable water reservoir in two compartments with integrated inlet and outlet valve houses; • New OSEC building; • Diversion of existing 1600mm diameter pipeline to connect to the existing 4.5Ml reservoir; • New pipelines to connect existing inlet and outlet supplies to new reservoir; • Re-laying of a section of the existing overflow/drainage pipeline and provision of overflow attenuation area and overflow de-chlorination system; • New scour pipeline to connect to existing foul sewer on Páirc Mhuire; • Surface water collection systems and attenuation
