- eutrophication
means the enrichment of water by nutrients, especially compounds of nitrogen or phosphorus, or both, causing an accelerated growth of algae and higher forms of plant life to produce an undesirable disturbance to the balance of organisms present in the water and to the quality of the water concerned;
- individual system
means a sanitation facility that collects, stores, treats or disposes of domestic wastewater from buildings or parts of buildings not connected to a collecting system.
- load
means the amount of organic biodegradable matter measured as BOD5 in urban wastewater, expressed in p.e., or of any pollutant or nutrient, expressed in mass units per time;
- micropollutant
means a substance as defined in Article 3(1) of Regulation (EC) No 1907/2006 of the European Parliament and of the Council, including its breakdown products, that is usually present in the aquatic environment, urban wastewater or sludge and that can be considered hazardous to the environment or human health on the basis of the relevant criteria set out in Parts 3 and 4 of Annex I to Regulation (EC) No 1272/2008, even in low concentrations;

- quaternary treatment
means treatment of urban wastewater by a process which reduces a broad spectrum of micropollutants in urban wastewater;
- sanitation
means facilities and services for the safe, hygienic, secure, and socially and culturally acceptable management and disposal of human urine and faeces, and for the changing and disposal of menstrual products, that provide privacy and ensure dignity;
- secondary treatment
means treatment of urban wastewater by a process generally involving biological treatment with a secondary settlement or another process which reduces biodegradable organic matter from urban wastewater;
