16. Reverse Flow Reverse flow in a sewer system is rare, but in this situation a 12-in sewer is overpowered by a much larger downstream interceptor. During a rain event, […]
15. SSO Overflow Pipe This 10-in sewer is equipped with an 8-in overflow pipe located in the downstream manhole. During a rain event, this sewer experiences backwater and surcharged conditions […]
14. SSO Downstream The scattergraph depicted here reveals backwater and surcharge conditions that result in a sanitary sewer overflow (SSO) downstream from this monitoring location.
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 […]
