5.3 Construction, extension and operation of waste water collection and treatment (climate change mitigation)

Kurzbeschreibung

Construction, extension and operation of centralised waste water systems including collection (sewer network) and treatment. The economic activities in this category could be associated with several NACE codes, in particular E37.00 and F42.99 in accordance with the statistical classification of economic activities established by Regulation (EC) No 1893/2006.

Technische Bewertungskriterien

Technical screening criteria Substantial contribution to climate change mitigation 1. The net energy consumption of the waste water treatment plant equals to or is lower than: (a) 35 kWh per population equivalent (p.e.) per annum for treatment plant capacity below 10 000 p.e.; (b) 25 kWh per population equivalent (p.e.) per annum for treatment plant capacity between 10 000 and 100 000 p.e.; (c) 20 kWh per population equivalent (p.e.) per annum for treatment plant capacity above 100 000 p.e. Net energy consumption of the operation of the waste water treatment plant may take into account measures decreasing energy consumption relating to source control (reduction of storm water or pollutant load inputs), and, as appropriate, energy generation within the system (such as hydraulic, solar, thermal and wind energy). _____________ ( 207 ) The Infrastructure Leakage Index (ILI) is calculated as current annual real losses (CARL)/unavoidable annual real losses (UARL): The current annual real losses (CARL) represent the amount of water that is actually lost from the distribution network (i.e. not delivered to final users). The unavoidable annual real losses (UARL) take into consideration that there will always be some leakage in a water distribution network. The UARL is calculated based on factors such as the length of the network, the number of service connections and the pressure at which the network is operating. 2. For the construction and extension of a waste water treatment plant or a waste water treatment plant with a collection system, which are substituting more GHG-intensive treatment systems (such as septic tanks, anaerobic lagoons), an assessment of the direct GHG emissions is performed ( 208 ). The results are disclosed to investors and clients on demand. Do no significant harm (‘DNSH’) (2) Climate change adaptation The activity complies with the criteria set out in Appendix A to this Annex. (3) Sustainable use and protection of water and marine resources The activity complies with the criteria set out in Appendix B to this Annex. Where the waste water is treated to a level suitable for reuse in agricultural irrigation, the required risk management actions to avoid adverse environmental impacts have been defined and implemented ( 209 ). (4) Transition to a circular economy N/A (5) Pollution prevention and control Discharges to receiving waters meet the requirements laid down in Council Directive 91/271/EEC ( 210 ) or as required by national provisions stating maximum permissible pollutant levels from discharges to receiving waters. Appropriate measures have been implemented to avoid and mitigate excessive storm water overflows from the waste water collection system, which may include nature-based solutions, separate storm water collection systems, retention tanks and treatment of the first flush. Sewage sludge is used in accordance with Council Directive 86/278/EEC ( 211 ) or as required by national law relating to the spreading of sludge on the soil or any other application of sludge on and in the soil. (6) Protection and restoration of biodiversity and ecosystems The activity complies with the criteria set out in Appendix D to this Annex.
