Exact Stormwater Management

What Exact Stormwater Management does

Exact Stormwater Management is a privately held stormwater services firm headquartered in Midlothian, Virginia, founded in January 2013 by Sean Simonpietri after 20 years in the construction industry. The company installs, inspects, maintains, and rehabilitates stormwater Best Management Practice (BMP) systems — including bioretention, underground detention (R-Tank, StormTech, Cultec, StormTrap, StormCapture), permeable pavements, sand filters, hydrodynamic separators, wet/dry ponds, infiltration basins, and geomembrane liners — for commercial property owners, general contractors, HOAs, municipalities, land developers, and engineering firms across 12+ southeastern and mid-Atlantic states. Its technical foundation is state-certified inspection expertise, including Virginia DEQ Stormwater Inspector Certification, combined with familiarity across multiple state regulatory frameworks (VESMP, TPDES, NPDES, LPDES, ADEM, SCDHEC, MDE, NCDEQ, IDEM).

The business is delivered through a direct field-sales model with assigned regional representatives and physical offices in Midlothian, VA and Jacksonville, FL. Revenue comes from project-based installation engagements, certified inspection work, and recurring annual maintenance contracts; pricing is quote-based and not publicly disclosed. Marketing relies on state-specific landing pages, an educational Learning Center, direct phone/email outreach, and earned media from community environmental projects. The firm also installs proprietary products (HydroTurf turf reinforcement mats, Curb Inlet Screens) and recently launched an Aquatics Group for pond restoration and a sub-brand called Exact Street Impressions for stamped asphalt applications.

Ownership remains founder-controlled, with Sean Simonpietri (Founder & COO), Jennifer Simonpietri (partner since 2016, operations), and Molly Winegar (partner since 2023, operations and HR). In 2020 the company acquired Landsaver Environmental — strengthening containment, specialty installation, and erosion-control capabilities. No institutional capital, private equity, or venture capital backing is identified in the source materials.

Revenue model

1. Stormwater Facility Installation: Installation of stormwater BMPs including green infrastructure, underground detention, bioretention, grass and permeable pavements, dry swales, sand filters, and check dams. This is a project-based, one-time revenue stream driven by construction and development activity.
2. Stormwater Facility Inspection & Maintenance: Certified inspection services and annual maintenance programs for stormwater BMPs including ponds, underground detention, bioretention, sand filters, hydrodynamic separators, and more. This generates recurring revenue through maintenance contracts and periodic inspection fees.
3. Erosion Control Services: Silt fence, safety/tree protection fence, hydroseeding, inlet protection, check dams, and erosion matting services for construction sites.
4. Geomembrane Liner Installation: Impermeable liner installation for ponds, underground detention, secondary containment, tank farms, and liner repairs. Installation of liners using PVC, HDPE, LDPE, RPP, RPE, XR-5, and other materials.

Core offering

Exact Stormwater Management installs, inspects, and maintains stormwater Best Management Practices (BMPs) including bioretention, underground detention, permeable pavements, sand filters, water quality separators, hydrodynamic separators, wet ponds, dry ponds, infiltration basins, and geomembrane liners across 12+ southeastern U.S. states. The company also provides erosion control, pond management (Aquatics Group), engineered product installation (HydroTurf, Armormax, Flexamat), and stamped asphalt services via its Exact Street Impressions division.

Product overview

Exact Stormwater Management is a service-oriented company providing stormwater BMP installation, maintenance, and inspection services across the southeastern U.S. The company operates as a single integrated service offering rather than a platform-plus-modules architecture. Services include stormwater facility installation, BMP maintenance and inspection, erosion control, liner/containment installation, and an Aquatics Group for pond management. The company also installs proprietary products including HydroTurf turf reinforcement mats and Curb Inlet Screens, and works with various underground detention systems (R-Tank, StormTech, Cultec, StormTrap, StormCapture). A separate division called Exact Street Impressions handles stamped asphalt for crosswalks and bike lanes. The company acquired Landsaver Environmental in 2020, which added containment, specialty installation, and erosion control capabilities.

Broad incumbents

• Ferguson Waterworks: National distributor of water, sewer, and stormwater products including R-Tank detention systems and BMP components that Exact uses. Operates as a broader incumbent with deeper geographic coverage and product breadth than Exact's regional services focus.
• Cardno (now Stantec): Global engineering and environmental services firm (acquired by Stantec) with strong stormwater and water resources practice. Competes with Exact for environmental compliance, inspection, and design work, particularly on larger developer and municipal projects across the Southeast.
• Civil & Environmental Consultants (CEC): National environmental engineering and consulting firm offering stormwater permitting, design, and inspection services. Overlaps with Exact on the inspection and compliance side, particularly for larger municipal and developer clients with bigger project scale.
• Tetra Tech: Global consulting and engineering firm with a sizable water and stormwater practice serving municipalities, developers, and federal clients. Competes with Exact for inspection, compliance, and design-build work, particularly on larger municipal MS4 and TMDL engagements.
• Advanced Drainage Systems (ADS): Leading manufacturer of stormwater management products including pipe, chambers (StormTech), and water quality systems. Provides products Exact installs while also competing for larger engineered projects as a vertically integrated national player.
• Oldcastle Infrastructure (CRH): National infrastructure products and solutions provider, including precast concrete stormwater systems (StormTrap/StormCapture) that Exact installs. Competes indirectly as a manufacturer with broader reach and deeper capital than Exact's services-focused model.
• Contech Engineered Solutions: Large national manufacturer and solutions provider of stormwater management products (pipes, chambers, separators, filters) used in BMP installation. Provides the underlying products Exact installs and is a broader incumbent competing for engineering-specified projects in the same southeastern markets.

Direct peers

• ACF Environmental: Mid-Atlantic and Southeast stormwater BMP installation, inspection, and maintenance contractor. Comparable to Exact in lifecycle service offerings, certified-inspector positioning, and customer mix across developers, HOAs, and municipalities.
• Stormwater Maintenance & Consulting: Regional stormwater BMP inspection and maintenance services firm operating in the mid-Atlantic and Southeast. Directly competes with Exact in providing certified inspection, maintenance, and compliance documentation for the same customer base of HOAs, commercial property owners, and municipalities.
• Stormwater Pros: Regional stormwater inspection, maintenance, and BMP services firm serving southeastern U.S. markets. Directly comparable to Exact in service mix (install, inspect, maintain), customer segments (HOAs, commercial, municipalities), and reliance on certified inspectors.
