Primary discharge accounts for 87% of total pe in the agglomeration, which passed for BOD/COD and failed for TSS. However, secondary discharge accounts for 13% of total pe in the agglomeration, which only receives primary treatment. Therefore does not comply with requirements of Article 4. More stringent treatment than secondary is provided at this WWTP. However, as the agglomeration is less than 10,000 p.e., it is not subject to the requirements of Article 5. As agreed with the uwwtd helpdesk on 11.07.18, it was necessary to default this agglomeration to ‘Pass’ with regards to N/P removal to avoid data blockers. It is possible that in some cases the agglomeration may not have achieved the N/P quality and sampling standards in the Directive.
Forward looking aspect
Identified reason(s) for non compliance: 
Absence of secondary treatment for some of the agglomeration.
Measure(s) to reach the compliance needed for UWWTP: 
Works ongoing - WWTP upgrade at design stage. Further work - WWTP upgrade.

Any relevant comment on UWWTP: 
Below the size threshold for mandatory compliance with Article 4 effluent quality standards in the previous reporting exercise (2014) but the estimate of agglomeration size increased above the threshold in 2016. A more detailed assessment of the load undertaken in 2017 shows that the load is now 1,955 p.e. which is under the threshold. Reduction due to the connected domestic load figure and a refinement of connected load calculation.
