As part of the project, we have developed a number of animations to
show how the mostly unseen combined sewage and and stormwater infrastructure
system works. We have modeled various flooding scenarios, as engineers
have developed carefully orchestrated plans for different-volume rain
The movie playing now is one of those movies.
The grey is the sanitary sewer conduit.
The green is the stormwater/Stony Brook conduit.
When the grey changes to green, it means that the two sewers combine.
