How a French Drain Solves Water Problems
A French drain is a gravel-filled trench that redirects water away from your foundation. At the core is a perforated SDR 45 pipe, wrapped in stormwater fabric to prevent clogs and allow smooth water flow. It's ideal for managing heavy rain, high water tables, and surface runoff.
- Diverts groundwater and rain runoff
- Prevents basement flooding
- Protects foundation and landscaping
- Low maintenance and highly durable
Why French Drains By CT Stormwater Authority?
French drains absorb excess surface water, preventing the flooding of lawns, patios, pathways, and driveways. They help dry out lawns and basements by redirecting excess surface water. They are easiest to install during new home construction, but they can be added later.

Our French Drain Installation Process
We take a detailed approach to every French drain system we install in Greenwich:
- Evaluate your property and identify problem areas
- Design a custom drainage system to handle your runoff
- Excavate trenches and install SDR 45 pipe with gravel backfill

How CT Stormwater Installs French Drains
At CT Stormwater Authority, our skilled, certified technicians install French drains using the following process:
- Sides and bottom of trench are covered with water-filtering fabric in collection area to block dirt or debris from entering.
- Porous drain tile is placed over fabric and into the trench.
- Non-porous pipe or line is installed to move water away from collection area.
- Water collection area is filled with gravel or rocks; remaining trench is backfilled with soil.
