| Stormwater is discharged in to the ocean. | Most of the DW is supplied by the centralised DW system. The source is surface water in lake Bolmen, Sweden. In addition, recovered water from the ANCHOR greywater pilot will be prepared to replace potable water in the swimming hall. | GW is locally treated in a EBPR activated sludge with fecl3 precipitation, nanofiltration and ozontion (for OMP removal). Permeate is post treated to DW standard and the bleed water discharged in to the ocean. |

| BW is collected separately and digested in a neighbourhood UASB, nutrient recovery as struvite and ammonium sulphate (ammonia stripper). | FW is collected in a separate LPS system and treated in a separate anaerobic reactor. Effluent can be joined with BW effluent and undergo the same nutrient extraction steps. | Biogas from both digestors is delivered to the centralised gas grid. |
