Dear Brian Meaney,

In response to the Regulation 18(3)(b)-2 request for further information notice created on 30 July 2012 please see below relevant information.

Aczvding to Section 0.9, tbe pupulatiun equivalent of the Paufstvwn agglomeratiOn is 1,964. This is in e x d a n c e of the design capscity of the pfanG which is 1,000 PE Confim tbese fJgums. Cunfirtn also whether tihere am any frrrtlzer plans to incmase Crreatment process capacity at tlie Pautstvwn freatmeni works. Prvvide timeflames and dates for cornpietion of anyprvpsd umrade wuk5 andcunfirm that emi&siuns h m the upgraded pfant w7f mmpfy with the provisions of the Cound Directives specifid in Sectjon GI.

Irish Water recently conducted a review of the agglomeration population equivalent for Paulstown. The current population equivalent of the agglomeration is estimated to be 881 P.E based on 2011 CSO population data and a 10% non-domestic factor, The population equivalent for the agglomeration in 2020 is estimated to be 902 P.E, based on an average annual growth rate of O.406Yo1 per annum for 6 years.

There are currently no operational issues with the wastewater treatment plant. Irish Water currently have no plans to upgrade the plant.
