13. SSO Upstream The scattergraph depicted here reveals backwater and surcharge conditions that result in a sanitary sewer overflow (SSO) upstream from this monitoring location. These conditions result in a capacity loss […]
12. Continuous Backwater This scattergraph displays data obtained during dry weather from a flow monitor installed in a 27-in sewer just upstream from a 12-in Parshall flume. By design, the […]
11. Backwater and Surcharge Orifice The scattergraph show here reveals the presence of a dead dog and a downstream restriction that cause backwater and surcharge conditions. However, note that flow […]
10. Backwater and Surcharge Most surcharge conditions result from downstream restrictions that reduce sewer capacity. The flow monitoring data shown here indicate that this sewer operates as expected up to […]
09. Surcharge Surcharge conditions are common in sewer systems, especially during wet weather event. The flow monitoring data shown here indicate that this sewer operates as expected up to its […]
