Tommy and John at AllGreen Landscape did an incredible job of designing a new driveway and entrance to our house, as well is helping us find a great pool contractor and doing all the landscaping around it and a new patio. I especially appreciate the fact that their crew has been with them for more than a decade, and they are all great guys. The whole team has worked with us closely to keep it all maintained and looking beautiful.

Expert Underdrain Cleanout, Inspection & Maintenance in Alexandria, VA
AllGreen Solutions provides comprehensive underdrain cleanout, inspection, and maintenance services for subsurface stormwater systems throughout Northern Virginia and Maryland. We utilize high-resolution camera diagnostics and targeted hydro-jetting to locate and clear silt, roots, and crushed sections in underdrain lines — restoring proper water draw-down in bio-retention cells, detention basins, and low-lying landscapes to keep systems operating at peak performance.
Underdrains are the hidden backbone of stormwater BMPs. When they become clogged or damaged, standing water accumulates, pollutant removal efficiency drops, and regulatory compliance is put at risk. Our team combines CCTV camera inspection with precision jetting to diagnose the exact location and nature of each obstruction before any work begins — whether it's sediment buildup, root intrusion, or a structurally compromised section of pipe.
Routine maintenance programs from AllGreen Solutions keep underdrain systems functioning between regulatory inspection cycles, reducing the risk of costly emergency repairs and helping property owners and municipalities meet stormwater permit requirements. We serve commercial properties, HOAs, municipalities, and state agencies across the Northern Virginia and Maryland region. Contact AllGreen Solutions to schedule underdrain cleanout, inspection, or maintenance service today.

FAQ
Underdrain Cleanout, Inspection & Maintenance FAQ
Common questions about underdrain cleanout, inspection & maintenance in Alexandria, VA.
The right choice depends on your site's drainage area, soil type, and runoff volume. A detention pond releases water slowly after a storm, while a retention pond holds a permanent pool that filters pollutants year-round.
Commercial sites, HOA communities, and larger residential parcels in Alexandria most often require a pond when development increases impervious surface area. Properties in low-lying areas or on clay-heavy soil also benefit from on-site pond storage.
Yes, pond owners in Alexandria are responsible for keeping their stormwater facility in working order. Routine maintenance includes sediment removal, vegetation management, and inspection of inlet and outlet structures.
Yes, a correctly sized pond captures and holds runoff during storms, reducing the volume and speed of water leaving your site. This directly lowers flood risk for structures, parking areas, and adjacent properties in Alexandria.
We calculate existing and proposed runoff rates based on your site's impervious area, drainage patterns, and soil conditions in Alexandria. That data drives the pond sizing to meet local stormwater management targets.
Alexandria's Stormwater Utility Fee Credit Program allows property owners who install eligible BMPs to apply for a fee reduction. We recommend contacting the City of Alexandria's Stormwater Management Division to confirm eligibility for your specific installation.
