Summary:

The article presents a analysis of amount flow to sewage to treatment plant type SBR – BIOVAC in years 2001–2004. The Treatment plant is located in Książ Wielki in province małopolska. The Treatment plant gave and started in 2000 year. The Treatment plant designed to flow sewer Q=200 m³∙d^-1. Analysis amount flow to sewer allowed to compare actual flow to sewer with flow to founded in project. From 2001 year do 2004 year successive connected next users to sewage system, because of that increased amount flow to sewer. In 2001 year flowed to middle 70,0 m³∙d^-1, however in 2004 year flowed to middle 106,7 m³∙d^-1. In analysis time four years the most flow to in months march and december – middle 97,0 m³∙d^-1, however months the smallest flow to in january and june – middle 77,0 m³∙d^-1. After analysis middle flow to sewer in individual week days the most flow to write down in sundays (91,5 m³∙d^-1) and the smallest in saturdays (81,0 m³∙d^-1). Maximum deviations from middle days flow to took ± 10%. Actual flow to sewer is about 50% Q_śr.d. From analysis results research follow to treatment plant flow to every year more sewer. Trend rising flow to sewer allow affirm in the nearest years the treatment plant will achieve full capacity. Is possibility extend sewage system and connect next households to aim achieve full capacity of treatment plant.
