Install Gutter Drainage Underground in Connecticut

After helping with inspections, reprts, and permits we will install a new stormwater underground drainage system or retrofit the old one

Connecticut Stormwater Authority offers installations of Contactor and Recharger chambers on residential and commercial properties. Our engineers, or yours, can design the system based on your stormwater requirements then install gutter drainage underground. We also have direct access to CULTEC staff engineers for design. We aim to provide a long-term solution to your gutter system, ensuring all stormwater is coordinated away from the house or building, without causing damage to the foundation.

Currently, our installation provider is installing CULTEC stormwater management systems in Fairfield County, CT, Westchester County, NY and will soon be expanding installation services to select locations across the U.S. and Canada.

Stormwater drainage systems require professional maintenance to clean and maintain.

Already have a storm drainage system? We can also retrofit your current underground drainage system to make your life easier, allowing for repairs to any damage caused by a build-up of dirt or other debris that may have built up over time. Contact us today and schedule your free estimate for installation or retrofitting in Riverside, Greenwich, Stamford, & nearby Fairfield County!



Connecticut Stormwater Authority offers the opportunity to reduce maintenance and maximize the performance of CULTEC stormwater management systems with the StormFilter T-80 and StormFilter 330.

CULTEC's StormFilter® T-80

CULTEC StormFilter® T-80 is a cost-effective filtration unit used to remove leaves and debris from rainwater collected by catch basins or gutters. StormFilter® T-80 prevents outflow systems and piping from being clogged with leaves and debris. Rainwater is piped into the end wall of the StormFilter® T-80 and passes through a removable filter. Pollutants are collected within the tank and may be removed by a wet/dry vac. The filter bag may be cleaned or replaced. This compact unit is easy to install and simple to maintain. It is perfect for treating roof and driveway runoff from the rain for light commercial or residential applications. When the filter frames are not installed, the StormFilter® T-80 may be used as a holding tank or catch basin.

CULTEC's StormFilter® 330

The CULTEC StormFilter® 330 is designed to be a secondary in-line filter system that effectively removes many of the smaller particles not eliminated by conventional structures during the pretreatment process. CULTEC StormFilter® 330 is a pass-through filter system and has a welded and secured solid bottom.

Inspection Ports and Other Fitting Alterations

When an inspection port is lacking, it may be best to install one for the sake of maintenance. Inspection ports are retrofitted and situated on the separator row (or inlet row) to allow us an easy look into the chamber. This may save time and money on maintenance if access to your chamber beds is difficult or impossible. We can retrofit an inspection port to your existing system and may also suggest an alteration to your current system layout to improve access, performance, or both.
