Note: – When tailwater is far higher than expected (like an unusual tide event or surge event), it may backup the headwater and cause flooding even during a normally routine storm event since there is nowhere for water to go.

This happens when there is no means to collect the water to get in to the pipes and/or to the downstream collection.
