Section 1. Executive Summary and Introduction to the 2015 AER 1.1 Summary Report on 2015 This Annual Environmental Report has been prepared for D0007-01, Athlone, in County Westmeath, in accordance with the requirements of the wastewater discharge licence for the agglomeration. There are no specified assessment reports included as an appendix to this AER. The agglomeration is served by a wastewater treatment plant with a Design PE of 30,000. The treatment process includes the following: -
Preliminary Treatment (Screening)
Secondary Treatment (Extended Aeration with Anoxic Zone)
Chemical dosing for phosphorus removal (Alum Dosing) The final effluent from the Primary Discharge Point was compliant with the Emission Limit Values in 2015. 2,433,720kgs sludge as dry solids was removed from the wastewater treatment plant in 2015 as dewatered sludge cake. Sludge was transferred to Mullingar WWTP (Reg. No. D0008-01). There were no major capital or operational changes undertaken in 2015. An Annual Statement of Measures is included in Appendix 7.1.

Annual Mean 192.34 493.60 223.14 6.03 38.04 8,431.64 27,029
Significance of results The annual mean hydraulic loading is less than the peak Treatment Plant Capacity as detailed further in Section 3.2 The annual maximum hydraulic loading is less than the peak Treatment Plant Capacity as detailed further in Section 3.2. The annual mean organic loading is less than the Treatment Plant Capacity as detailed further in Section 3.2. The annual maximum organic loading is greater than the Treatment Plant Capacity as detailed further in Section 3.2. The design of the wastewater treatment plant allows for peak values and therefore the peak loads have not impacted on compliance with Emission Limit Values.

* It should also be noted that Irish Water is unable to access the downstream sampling location as prescribed under Schedule B.3 Ambient Monitoring. The lands adjacent to all the sample locations are underwater for at least a period of 6-8 months of the year The results for the upstream monitoring are included as in Appendix 7.2. Significance of results
The WWTP was compliant with the ELVs set in the wastewater discharge licence as detailed in Section 2.2
The plant is compliant with the ELVs; therefore, based on this it is considered that the discharge is not impacting on water quality or the WFD status of the waterbody.
It is not considered that the WWTP is impacting upon the downstream drinking water abstraction point at Banagher, circa 36 km downstream.

3.3 Extent of Agglomeration Summary Report In this section Irish Water is required to report on the amount of urban waste water generated within the agglomeration. It does not include any waste water collected and created in a private system and discharged to water under a Section 4 Licence issued under the Water Pollution Acts 1977 (as amended).

% of total load generated in the agglomeration
Load generated in the agglomeration that is collected in the sewer network 100%
Load collected in the agglomerations that enters treatment plant Unknown
Load collected in the sewer network but discharges without treatment Unknown
Load generated in the agglomeration that is collected in the sewer network is the total load generated and collected in the municipal network within the boundary of the agglomeration. Load collected in the agglomerations that enters treatment plant is that portion of the previous figure which enters the waste water treatment plant. Load collected but discharged without treatment is that portion of the first figure which is discharged without treatment. The data in Table 3.3 is estimated based on influent monitoring as detailed in Section 2.1 above.
