2.3 Sustainable urban drainage systems (SUDS) (sustainable use and protection of water and marine resources)

Kurzbeschreibung

Construction, extension, operation and renewal of urban drainage systems facilities that mitigate pollution and flood hazards due to discharges of urban runoff and improve the urban water quality and quantity, by harnessing natural processes, such as infiltration and retention. The activity includes SUDS promoting infiltration, evaporation and other stormwater treatments (including water butts, site layout and management, pervious pavements, filter drains, swales, filter strips, ponds, wetlands, soakaways, infiltration trenches and basins, green roofs, bioretention areas and stormwater pre-treatment devices, including sand filters or silt removal devices (10)) and other innovative systems. The activity does not include nature-based solutions for flood and drought risk prevention and protection outside the urban environment (see Section 3.1 of this Annex). The economic activities in this category could be associated with several NACE codes, in particular E36.00, E37.00 and F42.9 in accordance with the statistical classification of economic activities established by Regulation (EC) No 1893/2006. (9) Council Directive 86/278/EEC of 12 June 1986 on the protection of the environment, and in particular of the soil, when sewage sludge is used in agriculture (OJ L 181, 4.7.1986, p. 6).

Technische Bewertungskriterien

Technical screening criteria Substantial contribution to the sustainable use and protection of water and marine resources The activity leads to a retention of rainwater in a specific area or to an improvement in water quality by complying with the following criteria: (a) the construction and operation of the sustainable urban drainage system is integrated in the urban drainage and waste water treatment system, as demonstrated by means of a flood risk management plan or of other relevant urban planning tools. The activity contributes substantially to achieving the good status and good ecological potential of bodies of surface water and groundwater or to preventing the deterioration of bodies of water that already have good status and good potential, and is carried out to ensure compliance with Directive 2000/60/EC (11) and Directive 2008/56/EC; (b) information is provided on the percentage of a specific area, such as a residential or commercial area, where rainwater is not directly drained but retained within the area site; (c) the design of the sustainable urban drainage system achieves at least one of the following effects: (i) a quantified percentage of rainwater in the catchment area of the drainage system is retained and discharged with a staggered delay to the receiving water bodies; (ii) a quantified percentage of pollutants, including oil, heavy metals, hazardous chemicals and microplastics, is removed from urban runoff before discharge to the receiving water bodies; (iii) runoff peak flow, with a return period in line with the requirements of flood risk management plans or other local provisions in place, is reduced by a quantified percentage. Do no significant harm (‘DNSH’) (1) Climate change mitigation N/A (2) Climate change adaptation The activity complies with the criteria set out in Appendix A to this Annex. (4) Transition to a circular economy N/A (5) Pollution prevention and control Depending on the origin of the received water and the different pollutant load, such as rainwater, rainfall run-offs from roofs, rainfall run-offs from roads, or stormwater, SUDS treat these waters before discharging or infiltrating the water into other environmental media. (6) Protection and restoration of biodiversity and ecosys­ tems The activity complies with the criteria set out in Appendix D to this Annex. The introduction of invasive alien species is prevented or their spread is managed in accordance with Regulation (EU) No 1143/2014 of the European Parliament and of the Council (12). (11) For activities in third countries, in accordance with applicable national law or international standards which pursue equivalent objectives of good water status and good ecological potential, through equivalent procedural and substantive rules, i.e. a water use and protection management plan, developed in consultation with relevant stakeholders which ensures that (1) the impact of the activities on the identified status or ecological potential of potentially affected water body or bodies is assessed; and (2) deterioration or prevention of good status/ecological potential is avoided. (12) Regulation (EU) No 1143/2014 of the European Parliament and of the Council of 22 October 2014 on the prevention and management of the introduction and spread of invasive alien species (OJ L 317, 4.11.2014, p. 35).
