REGULATORY REFERENCES
Referencia normativa: Romania
Regulatory framework of Romania · Directive (EU) 2024/3019: reported-capacity band 1,000 to 9,999 p.e.; obligations are set by agglomeration load, not by the capacity of this plant. Individual applicability is not determined in this profile.
SCENARIO
Reference energy scenario for this load estimate · simulator engine
what this estimate is · Inputs: 1,800 p.e. of reported load; equivalent average load 811 p.e. with the reference profile of Romania (hypothesis with reported load and reference profile; not a measurement). Open this scenario in the simulator · how it is calculated and what it is not.
Reference scenario computed on the server from the reported load and the country profile; an estimate, not a measurement. The simulator recomputes it when opened.

QUESTIONS
Frequently asked questions about this plant
What capacity does WWTP COSTESTI report?
Reported size: 3,600 h-e design capacity. Received load: 1,800 h-e. Units are retained without conversion.
What treatment is reported?
Treatment PS. Nitrogen, phosphorus and UV are shown only when explicitly reported.
How much energy would a reference plant use with the load of COSTESTI?
Aguas SB simulator reference scenario for 1,800 p.e. of reported load: 51,791 kWh per year (63.8 kWh per p.e. of average load), with aeration as 55 % of consumption. Estimate with the country reference profile; not a measurement of the plant.
