Public Works-Catch Basin

Show All Answers

1. What is an "overflow" or "bubbler" catch basin?

"Overflow" or "bubbler" catch basins are outlet points for an interconnected system of 2 or more catch basins designed to convey runoff water from one area to another in an effective manner. These generally exist where there is no nearby drainage main pipe to which the "overflow" catch basin may be connected. As such they fill up and "overflow" along the curbline to the next drainage system.

2. Why do some catch basins always seem to be clogged or flooding over?

Most likely this is what is referred to as an "overflow" or "bubbler" catch basin though it could be clogged so callus at (914) 235-3567. If you leave a message please leave a contact number so we may update you on our findings.

3. If I see water or debris in a catch basin does that mean it's clogged or needs to be cleaned?

Not necessarily. Many of the City of New Rochelle's catch basins are what are called "sump" catch basins. This refers to the fact that the outlet pipe that conveys water away from teh basin is higher than the bottom of the basin. This design is intended to "catch" solids, sediment and debris below the outlet pipe, in the basin "sump", to be cleared away by our staff. This minimizes the flow of solids and sediment to our waterways and limits the potential for buildup of these same materials in our drainage piping.
