Job completed for Stormwater Solution in Backcountry Greenwich, CT

Completion date: October 12, 2021

Location: Greenwich, CT

About this project:

This property is a block off of Lake Ave. and close to downtown Greenwich. The property was overtaken by surface runoff during Hurricane Ida in the summer of 2021. The driveway's catch basins all feed concrete detention chambers below the driveway and completely filled the chambers faster than they could infiltrate and drain. Additionally, a basement walkout was not outfitted with proper drainage and so the area collected an incredible amount of water during the storm, overtaking the door threshold. The solutions we executed on were to (1) drain the patio area completely during any water event and (2) create a dual pump system housed inside a new pump chamber situated above the detention chambers to empty the underground detention chambers when they reach a set water depth.
