Flow Measurement

Flow measurement is a missing link in computing why septic systems may fail. The impact of inflow and infiltration can be challenging when calculating the estimated flow on a sewer system. The actual flow may be further impacted with wet weather events and its impact may be ignored. Measuring flow should indicate a state of hydraulic overloading if evident in the performance of any septic or sewer system. The importance of knowing anticipated sewer flow can gauge potential problems. Daily flow can exceed the system design capacity, resulting in frequent sewer backups or puddling of sewage onto the ground surface. Sanitary sewer overflows are evident in cases where potential problems are compacted with additional flows. Values for estimated sewage flows will be compared. Inflow and infiltration are often not considered when sizing an onsite wastewater system or sewer collection system. Several solutions to measure gravity sewer flow accurately will be discussed.
