1.Number of agglomerations in EU Member States, by size categories (generated waste water load). Number of agglomerations with over 2,000 population equivalents (p.e.) per Member State and size category. The categories reflect the three main ranges of size defined in the Directive, each of which is subject to different legal obligations on treatment, depending on the nature of the area where waste water is discharged. The variation in distribution between countries reflects differences in their level of urbanisation and in the structure of urban areas. Germany has most agglomerations (3,927). It also has the largest number of very large agglomerations (above 100,000 p.e.): 174. There are four Member States (DE, FR, IT and ES) with over 2,000 agglomerations. The majority of EU countries (18) have fewer than 500 agglomerations. 2.Compliance rate and distance to target in 2016 2.1.Summary table per Member State in 2016, and change compared with 2014 status

COMPLIANCE RATE: Five countries are fully or almost fully compliant with all the Directive’s requirements (AT, DE, LV, LT and NL). Other five countries reach a very high compliance level (EL, FI, SE and UK). Seven countries are placed in a relatively high level (BE, DK, EE, FR, LU, PL and SK). Four countries are in a lower level of compliance (CY, CZ, ES and PT). At the other end of the scale, seven (BG, HU, IE, IT, MT, RO and SI) comply to a limited or very limited extent. Four countries (BE, BG, PL and RO) show positive trends (compliance rates increased above 1%) for all articles. The largest increases can be found for collection in BG, CY and RO, showing an increase of more than 10%; for secondary treatment in BG and SI, showing an increase of over 18%; and for more stringent treatment, with an increase of over 15% in BG, LU, PL, PT and SK. On average, the situation for EU-28 shows a compliance rate of 81% for collection and treatment. Taken in isolation, collection is doing best, with a compliance rate of 95%. DISTANCE TO TARGET Nine countries (AT, BE, DE, EE, FI, LV, LT, NL, SE) have already met very high targets in collection and treatment. However, a further eight (RO, MT, IE, SI, ES, CY, CZ, BG) still have a significant way to go, with distance to target values of over 15% or even 30% in collection and/or treatment. Malta has a very high value of distance to target for secondary treatment (95%). Excessive salt water in all treatment plants and farm manure discharges into collecting systems may explain the country’s poor bad performance. Other ten countries (DK, EL, FR, HU, IT, LU, PL, PT, SK and UK) have met high targets, but still have to make some effort at collection and/or treatment level. 2.2.Maps of compliance rate at regional level The maps in this chapter show compliance rates as percentages, corresponding to collection, secondary treatment, and treatment that is more stringent than secondary treatment. They cover all EU countries at the level of NUTS 2 regions. Legal compliance rates for collection and/or treatment reflect the waste water load of agglomerations > 2,000 p.e. found to be fully compliant with the requirements of collection (Article 3), secondary treatment (Article 4), or, where applicable, treatment more stringent than secondary (Article 5), compared to the total amount of waste water load that should meet such requirements, as per Article, expressed as a percentage. Legal compliance rates can be calculated at agglomeration, regional, national, EU level, etc., depending on the type of data taken into consideration and compared. Legal compliance with Articles 3, 4 or 5 does not reflect the fractions of load in agglomerations that are not fully compliant, but which are in line with the Directive’s requirements. For instance, an agglomeration that collects and adequately treats 80% of the waste water it generates is not considered compliant with Articles 3 and 4/5 of the Directive. This means it will not be included in the calculation of legal compliance rates at regional level, etc, even if the above-mentioned fraction of load is in line with the Directive’s requirements at collection and treatment level. It should therefore be noted that ‘legal compliance’ does not reflect the efforts yet to be made by each region (in the case of the maps in this chapter) to implement the Directive’s requirements in full. The concept is thus far less stringent than ‘distance to target’. 2.2.1.Map showing the rate of compliance with Article 3 (collection and IAS) Map showing compliance rate by NUTS 2 regions. All regions in BG, CY, HU, RO and SI, and some regions in ES, IT, PL and PT have low compliance rates for collection, some being in the 0-70% range.

2.2.2.Map showing the rate of compliance with Article 4 (secondary treatment) Map showing the situation by NUTS 2 regions. All regions in BG, CY, HU, MT, RO and SI, and some regions in CZ, EL, ES, FR, IE, IT, PL, PT, SK and the UK, have compliance rates for secondary treatment of below 85%. More than 20 EU regions even fall below 70%. 2.2.3.Map showing the rate of compliance with Article 5 (more stringent treatment than secondary) Map showing the situation by NUTS 2 regions. All regions of BG, CY, IE, MT, RO and SI, and some regions of BE, CZ, DK, EL, ES, FR, HU, IT, PL, PT, SE, SK and the UK, have a compliance rate of below 85% for more stringent treatment. More than 40 regions even fall below 70%. 2.3.Distance to target in individual Member States The term ‘distance to target’, used for the first time in the Commission’s reports in the 2014 reporting year, means the effort still required to comply in full with the Directive’s requirements on collection and treatment. ‘Distance to target’ values do not take account of agglomerations subject to under non-expired deadlines which therefore have no compliance obligations in this report (i.e. agglomerations in Croatia, those that are subject to a final deadline in Romania, or those that discharge waste water into sensitive areas of late designation under Article 5, where applicable). ‘Distance to target-treatment’ takes account only of collected waste water that is not properly treated (meaning that its treatment is non-compliant and/or the treatment level is inadequate). It does not take account of waste water that is not collected, and therefore not treated. 2.3.1.Distance to target for collection (Article 3) The distance to target for collection in Europe in terms of load is attributable mainly to six Member States which account for the highest absolute values: BG, CY, ES, HU, IT (between 174,000 p.e. and 565,000 p.e. each) and RO, with 4,377,000 p.e. It can be observed in this figure that the corresponding relative values are not so high in two of these countries (ES and IT), thus meaning that these countries have high amounts of p.e. In 20 Member States the distance to target is not beyond 0.5%. In five (BG, HU, SI, IT, EE) it is between 0.6 and 5.5%, while two (CY and RO) still have a distance to target of 17 and 26%, respectively. 2.3.2.Distance to target for secondary treatment (Article 4)

Fourteen Member States collectively account for most of the distance to target for secondary treatment in Europe in terms of load. Six countries (ES, FR, IE, IT, PT and RO) have values exceeding 1 million p.e. each, even though amongst them, only RO and IE also have high relative values (in the remaining four countries, the distance to target is not so relevant, in relative terms). Together, they account for over 32.5 million p.e. (or 88% of the entire distance to target for ‘secondary treatment’ in the EU). Another eight countries (BG 901,204 p.e., CY, EL, HU, MT, PL, SE and UK) reach levels between 147,000 p.e. and 901,000 p.e. each. In 10 Member States, the distance to target is equal or close to 0%. 2.3.3.Distance to target for more stringent treatment (Article 5) Sixteen Member States account for most of the distance to target for more stringent treatment in Europe in terms of load. Nine of these (BG, CZ, ES, FR, IE, IT, PL, RO and UK) are over 1 million p.e. Together they account for about 29.5 million p.e. (93% of the entire distance to target for ‘more stringent treatment’ in the EU). Only four of these countries (FR, IT, PL and UK) have rates of 10% or below, thus meaning that distance to target is not so relevant at relative level in each of the countries, respectively. Seven countries (DK, HU, MT, PT, SE, SI and SK) are between 111,000 p.e. and 519,000 p.e. each. Six countries (AT, CY, EE, DE, LU and NL) have zero or very close to 0 (EE) distance to target.

2.4.Rates of application of individual or other appropriate systems (IAS) in individual Member States 2.4.1.Classification by percentage of generated load connected to IAS This figure shows how much IAS is used by depicting the percentage of generated load for each country reporting the use of IAS. Of the 19 EU countries reporting IAS use, three (SK, HU and EL) use it in more than 10% of the generated load.

2.4.2.Classification of Member States by number of agglomerations which apply more than 10% of IAS This figure reflects the number of agglomerations reporting that more than 10% of their generated load is addressed through IAS. PL reported the highest number, with 575 agglomerations, while seven countries in total (PL, HU, IT, DE, SK, CZ and EL) reported over 200 agglomerations with a significant percentage of load addressed through IAS. It should be noted that a high number of agglomerations applying IAS does not necessarily entail a high IAS rate at country level. It indicates that many agglomerations rely, in a relatively high individual rate, on the use of IAS instead of collecting the generated waste waters in their entirety. 2.5.Compliance status of national capitals Member State Member State Capital city Generated load [p.e.] Legal compliance/distance to target > 0 (in percentage) Collection Secondary treatment More stringent treatment Collection and treatment UK United Kingdom London 10,636,249 C C C C FR France Paris 9,545,414 C C C C EL Greece Athens 5,200,000 C C C C DE Germany Berlin 4,353,563 C C NR C ES Spain Madrid 4,018,202 C C C C AT Austria Vienna 4,000,000 C C C C IT Italy Rome 3,005,533 C C NR C SE Sweden Stockholm 2,788,000 C C C C HU Hungary Budapest 2,722,686 C C C C PL Poland Warsaw 2,491,821 C C C C BE Belgium Brussels 1,460,000 C C NR (C) C NL Netherlands Amsterdam 1,099,208 C C C C PT Portugal Lisbon 1,063,000 C C NR C FI Finland Helsinki 926,700 C C C C LT Lithuania Vilnius 850,890 C C C C LV Latvia Riga 673,670 C C C C SK Slovakia Bratislava 530,000 C C C (NC) C (NC) EE Estonia Tallinn 468,000 C C C C CY Cyprus Nicosia 235,000 C C NR C LU Luxembourg Luxembourg 231,359 C C C C HR Croatia Zagreb 957,301 PD PD PD PD IE Ireland Dublin 2,225,120 C NC/100% NC/100% NC RO Romania Bucharest 2,159,995 NC/15% NC (PD)/100% NC (PD)/100% NC BG Bulgaria Sofia 2,037,000 NC/1% NC/1% NC/1% NC DK Denmark Copenhagen 1,100,000 C C NC (C)/33% NC (C) CZ Czech Republic Prague 1,533,060 C C NC/100% NC MT Malta La Vallette 615,810 C NC/94% NR NC SI Slovenia Ljubljana 302,293 C NC/2% NC/100% NC Legend C: compliant NC: non-compliant

PD: pending deadline NR: not relevant This table shows all the capital cities in the EU (all ‘big cities’), ordered by size but sorted into groups: compliant (on top); subject to pending deadlines (Zagreb, Croatia); and totally or partially non-compliant, at the end of the table. All but three capitals have maintained their reported compliance status. Of the three, two (Copenhagen and Bucharest) are less compliant than at the time of the previous report. Bucharest, whose deadlines have now expired, still discharges 52% of its waste water untreated, while the treatment of the remaining 48% falls short of required standards, especially as regards the removal of nitrogen and phosphorus. Copenhagen has reported that the Damhusåen treatment plant has failed to reach the required level of performance as regards phosphorus treatment. Dublin became non-compliant in 2012, and the downward trend continued in 2016. Bratislava became fully compliant during the reporting period, an improvement on its previous status, especially in terms of treatment. The previous results are given in brackets wherever there has been a change. Most capitals are fully compliant with the Directive’s requirements. In addition to legal compliance (/DTT), the values of distance to target in collection and treatment (what efforts are still required to reach compliance) are shown. For all the capital cities found to be compliant with the Directive’s various requirements (collection/secondary/more stringent treatment), the distance to target is equal to zero %. The values of distance to target in situations of non-compliance span a wide range. Some are very low (e.g. Sofia, for all dimensions; Ljubljana, for secondary treatment), but in most other cases distance to target is equal to 100%.

3.2. Open infringement cases There are currently 29 open infringement cases. Most of the non-compliant agglomerations identified in the implementation reports are covered by these cases. The vast majority of infringement cases listed below are ‘horizontal’, meaning that they cover groups of agglomerations within a Member State that are found, on the same legal basis, to be in breach of the legislation, usually in the same reported year. There are horizontal cases involving large agglomerations discharging waste water into ‘non-sensitive’ areas, or into sensitive areas; cases on small agglomerations; and ‘gap cases’, involving the compilation of agglomerations found to be non-compliant. ‘Gap cases’ may be initiated once all other types of cases have been brought at Member State level. They may involve non-compliant agglomerations with obsolescent facilities that were previously compliant, or those that were previously non-compliant but just not reported by a Member State in previous years. All the deadlines laid down in the Directive have expired as regards the EU-14 Member States plus the UK. Most of the types of cases referred to above have thus already been launched, if needed. A few ‘gap cases’, based on 2016 results, have yet to be launched. Some cases relating to the countries which joined the EU after 2004, corresponding to deadlines that expired in 2014 and 2015, have yet to be launched. In many of these cases, in particular, the Commission has also included an investigation of compliance by individual or other appropriate systems (IAS), where such systems are applied at relevant rates at the level of an agglomeration.
