Scattergraph

18. CSO Side Weir This scattergraph displays data from a flow monitor installed in a 120-in sewer located just upstream from a CSO regulator.  Dry […]

17. CSO End Weir Flow monitoring data provide a means to determine the duration and volume of a combined sewer overflow (CSO).  This scattergraph displays […]

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 […]

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 […]

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 […]
