WISE UWWTD Viewer – about Urban Waste Water Treatment agglomerations map

What is on the map?

The map reflects the most recent available information on implementation of the Urban Waste Water Treatment Directive (UWWTD) in EU-27 as reported by the Member States under UWWTD (91/271/EEC). The last reporting exercise under UWWTD article 15 was organised in 2009 (UWWTD2009), with the European Commission aiming to receive information on the implementation of the UWWTD in the reference year 2007 (situation as at 31/12/2007) or 2008 (situation as at 31/12/2008). For EU-15 (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden and UK) the latest date to fully comply with the Directive was 31/12/2005.

The data are displayed in the following four layers:

· Waste Water treatment pathways by Member State

· Proportion of total generated load by agglomeration size

· Waste Water Treatment agglomerations by size

· Waste Water Treatment pathways in agglomerations with a size > 150.000 p.e

Layer: Waste Water treatment pathways by Member State displays summary diagrams (pie charts) on pathways of waste water (= type of treatment) based on total generated load in p.e. of all agglomerations ≥ 2000 p.e. in a Member State. Summary diagrams, displayed at the scales 1 : 5.0 mio and less detailed, are presented as pie charts for each Member State. The size of each segment of the pie charts is proportional to the percentage of the waste water of all agglomerations attributed to the respective wastewater pathway, in other words expressing the pollutant load (in p.e.) undergoing the different types of treatment. The segments of the pies are coloured according to the different waste water pathways. The sum of these percentage values should be 100%. Please note that in cases , where the sum of percent values do not sum up to 100 % it is caused most often by incomplete dataset provided. EU-12 Member States are not obliged to report any information related to their agglomerations and related treatment plants, whenever their deadlines for implementation of the UWWTD (linked to different staged transitional periods) had not expired by 31.12.2007. Therefore such information may not be reflected in the viewer and appear as “no information”.

Layer: Proportion of total generated load by agglomeration size display summary diagrams on apportionment of the total generated load (in p.e.) between big cities/big dischargers and agglomerations smaller than 150 000 p.e. in a Member State

Layer: Waste Water Treatment agglomerations by size displays location and size of agglomerations. Individual agglomerations, displayed at more detailed scale are presented as purple dots with legend size reflecting the different agglomeration size classes.

Layer: Waste Water Treatment pathways in agglomerations with a size > 150.000 p.e displays Individual big cities /big dischargers (i.e. agglomerations of size > 150.000 p.e.) as pie charts, when zooming further in. The size of each segment of the pie charts is proportional to the percentage of the waste water of the agglomerations attributed to the respective wastewater pathway. The segments of the pies are coloured according to the different wastewater pathways. Agglomerations smaller than 150 000 p.e. are displayed as purple dots.

Receiving areas represented as catchments of sensitive areas, areas designated under the article 5(8) and normal areas are displayed in the additional layer.

What can I do?

· When you zoom out, you can view the agglomerations of a Member State and the situation on waste water treatment as one pie chart for each Member State.

· When you zoom-in, you can view the location and size of all agglomerations >= 2.000 p.e. in the EU as reported in the frame of the UWWTD.

· When pointing at a specific pie chart at country -level or at a specific agglomeration at a higher zoom-level, a pop-up window provides further details.Two types of information are available in pop-up window for big cities/big dischargers. Beside the information on the waste water pathways aportionment a chart illustrating trend in wastewater pathways apportionment reported in two successive reporting exercises (2007 and 2009) is displayed.

· Information in pop-up windows can be printed by mouse right-clicking or via the Print Screen tab on your keyboard

· With help of the "Find Location" - tool you can select an agglomeration or plant by ID or name and zoom-in to it.

· See more about functionalities in the general map description from the 'i' menu
