Operating costs
Based on the figures of 2010, the first year of normal operation for approx. 2900 PE:
| 2010 | |||
|---|---|---|---|
| Total | % | €/Eh | |
| Charge moyenne | 2900 EH | ||
| Entretien courant | 400 h x 20€/h = 8 000 € | 22 | 2 |
| Entretien des filtres | 620 h x 20€/h = 12 400 € | 34 | 3 |
| Entretien espaces verts | 500 h x 20€/h = 10 000 € | 28 | 2.5 |

| Electricité | 48 366 kWh x 0.08 = 3 942 € | 11 | 1 |
| Eau potable | 652 m³ x 1.2 = 782 € | 2 | 0.2 |
| Total | 39 329 € | 100 | 9 |
Filter maintenance = weeding + reed cutting + disposal of stubbles…. % = = percentage of total annual costs…. €/PE = cost per nominal PE, i.e. for 4000 PE. Not included: sludge scrubbing from the primary filters (every 10 to 15 years) and replacement of equipment.
