Questions regarding sewage plants in general
Which are the conditions to use a sewage plant?
The operation of a sewage plant requires the following:
• The dispensation from an obligatory connection to a large-scale wastewater treatment plant exists.
• The possibility of effluent drainage by means of seepage or into an existing receiving water is available.
• The water discharge permit is granted by the local water authority.
The responsible municipal association, the local water authority or the municipality provide information regarding this issue. When filling in the corresponding application forms, the BLUEVITA staff and its partners are ready to assist you.
How often does a sewage plant have to be maintained?
This is prescribed by law and is defined for the usual effluent classes C and D as two times per year. Once a year, a laboratory analysis is required. The maintenance reports and the analysis results have to be presented to the local water authority annually.
Can the clarified effluent be re-used?
The clarified effluent is still considered as wastewater and thus, must not be re-used in any case. The sewage plants clean the wastewater, but are normally not able to degerm it. This means that pathogenic germs and bacteria may still exist in the effluent, when it leaves the sewage plant. For that reason, the clarified effluent must seep away or flow into a receiving water.
