Another Batch of Cleaner Catch Basins!

After a patch of warmer weather, installation was complete for the combined project of Carmel-CF-901 and Carmel-CF-902 in March  2022. Working with our design firm, Dunn & Sgromo Engineers, the project had gone through several different design alternatives before we selected catch basin inserts as the most economic and effective option. This is a part of our on-going study of implementing catch basin inserts to treat stormwater within existing infrastructure, throughout the entire East of Hudson watershed.

The project targets the Willow Ridge neighborhood, located in the Town of Carmel NY. This neighborhood was built before the stricter requirements of the East of Hudson Watershed were put in place, meaning that this was a prime location for a stormwater retrofit! Throughout the development, there are wide roads, cul-de-sacs, roofs and driveways all of which get covered in contaminants from daily use. When it rains, stormwater collects these pollutants, flows into the nearest catch basin and travels into the West Branch of the Croton River, ultimately landing in the Croton Falls Reservoir. The pollutants, such as Phosphorus, Nitrogen, rubber, oils and other heavy metals directly affect recreational opportunities in the area, potentially overloading nearby waterbodies which can lead to decreased aquatic life, increase chance of harmful algal blooms, and overall water health decline. Installation of these units helps the entire watershed by reducing the amount of pollution entering our waterways, while also allowing the easy removal of sediment.
