Greenwich Yard Drainage Solutions – Prevent Flooding & Erosion

At CT Stormwater Authority, we deliver comprehensive yard drainage solutions in Greenwich, CT—designed to prevent standing water, protect landscaping, and stop erosion before it damages your property. From trench drains and yard catch basins to French drains and downspout tie-ins, we customize stormwater systems to suit your home’s needs and adhere to all Town of Greenwich drainage regulations.

Custom Yard Catch Basins & Trench Drain Installation

Our yard catch basins and trench drain systems are engineered to collect surface runoff across lawns, patios, and driveways—especially useful on sloped lots in neighborhoods like Cos Cob, Old Greenwich, and Riverside. These systems channel water into SDR 45 piping networks that lead to storm drains, dry wells, or CULTEC chambers. We size the systems based on rainfall volume and slope using civil-grade calculations.

Each installation includes:

Polymer or concrete trench grates rated for pedestrian or vehicle loads
Access risers and cleanouts for easy maintenance
Filter fabric and stone bedding to prevent clogging
Edge-to-edge integration with patios, walkways, or pool decks

French Drain Installation & Downspout Tie‑Ins

French drains are our go‑to solution for capturing groundwater and redirecting it before it reaches your foundation. When tied into roof downspouts, these curtain drain systems serve as a first line of defense against runoff. We excavate trenches, install crush-resistant SDR 45 pipe surrounded by aggregate and filter fabric, then connect everything to a discharge outlet or CULTEC infiltration system.

This integrated approach is especially effective in Greenwich properties with tight basements or slope-grade challenges. It's also ideal for Town stormwater compliance, and increases your property’s resale value by preventing water damage long-term.

Landscape & Erosion Control Management

We offer geo-textile-lined drainage swales, grade transitions, and natural stone solutions to control erosion on hillsides and garden beds typical of Northern Greenwich, Backcountry, and Hillcrest. Our team installs rock or vegetated swales, silt fences, and mulched terraces to slow and disperse runoff. These systems reduce soil movement, protect foundations, and preserve plantings.

For driveways and retaining walls prone to seepage, we incorporate drainage blankets and weep holes into the design, ensuring water is diverted away from key structural elements and limiting hydrostatic pressure.

Frequently Asked Questions – Yard Drainage in Greenwich

What is a CCTV drain inspection?

A CCTV inspection uses a waterproof HD camera fed into your underground drain lines. It captures live footage of blockages, root intrusions, or pipe damage without any digging.

How much does a CCTV inspection cost in Greenwich?

Most residential inspections start at $350. Full packages that include jetting and a video report typically range from $500 to $1,200, depending on pipe length and access.

What’s the difference between hydro jetting and snaking?

Snaking clears a path through a blockage, but hydro jetting fully scrubs the inside of the pipe with high-pressure water (up to 4,000 PSI) to restore full flow and prevent future clogs.

Can I get a copy of the inspection video?

Yes. We provide HD video files, timestamps, and a audible summary of our findings. These can be used for documentation, maintenance planning, or town compliance.
