A Smarter Way to Manage Stormwater Compliance

SW² gives construction companies a smarter way to manage stormwater compliance. From digital SWPPP inspections to automated reminders and mobile data entry, everything lives in one connected system.

Your team can log findings from the field, update site maps in real time, and generate compliant reports without chasing paperwork. Instead of reacting to inspections, you stay prepared every day. Compliance becomes part of your workflow, not a disruption to it.

Make Stormwater Compliance Visible Across Every Active Construction Site

On active construction sites, compliance often breaks down when inspections and routine compliance tasks are managed in separate places. A weekly log stays in a trailer. A rain event occurs, but precipitation is not clearly documented. Corrective actions are discussed, yet never formally tracked. These are common issues on fast-moving projects.

SW² gives construction firms stormwater management software built to manage inspections in the field and office. Inspectors log findings from mobile devices, NOAA weather data connects automatically, and corrective actions stay visible until closed. The result is stronger compliance tracking, proactive stormwater management, and less administrative waste across every job site.

Manual Stormwater Tracking vs. The SW² Process

The Manual Way The SW² Way
Paper inspection logs that get lost, damaged, or forgotten in trucks Instant mobile inspection entries saved securely in the system
Manual weather checks and handwritten precipitation records Automated NOAA weather syncing built into each project
Emails, texts, and calls scattered across teams Centralized alerts and reminders tied to inspections and deadlines
Site maps updated separately from inspection reports and are cumbersome to manage and track Real-time map updates connected directly to inspection findings
Time spent compiling compliance reports before audits One-click ability to generate reports with a clear audit trail

We’ve Built a Reputation

Justin Tourdot

"The SW² platform has been invaluable in keeping all of our stormwater records current and readily accessible. I routinely get inspected by local and state agencies and the SW² documentation has always been central to keeping us in compliance. I’ve been using it since its inception and I refuse to allow paper binders and paper maps for permit compliance documentation."
Gabe Perez

"SW² is the best stormwater/environmental compliance software I’ve used to date. The maps are easy to edit and update in real time. All the documents relevant to the SWPPP are easy to upload, organize, edit, and access. The findings for each inspection are easily searchable prior to a maintenance visit or regulatory inspection."
Courtney Roen

"Thanks to SW² for making SWPPP so much easier. I’m constantly learning new things, and the updates make using the app even better. The permit tracker is also a massive benefit. This is the reason I enjoy SW² so much."
David Ramirez
Director of Environmental Compliance, Northline Construction Group
“On a typical project, we are managing multiple inspections a week, rain event triggers, and constant site changes. Before moving to SW², a lot of our time went into tracking paperwork and confirming records were complete. Now our inspections, weather data, and corrective actions are all documented in one system. When we have a regulatory visit, we can walk through our records confidently because everything is organized and time-stamped. It has brought consistency to our compliance process across every job site.”

Built for Scalable, Defensible
Construction Compliance

Construction projects move quickly, but compliance requirements do not slow down. Learn how SW² helps construction firms manage stormwater obligations across single sites or multi-phase developments without losing visibility. You get a scalable compliance framework that supports growth, reduces risk, and stands up to regulatory review.

  • Audit Ready with Custom Form Templates

    Generate custom forms and compliance reports that align with ever changing stormwater permits and local stormwater regulations. Inspection data is captured correctly and consistently across every site, helping your team stay ready for local or state inspections without last-minute scrambling.

  • Real-Time Field Inspections and Mobile Data Entry

    Inspectors complete inspections and corrective actions directly from a phone or tablet using stormwater inspection software built for active construction sites. Optional photos, notes, and corrective actions are attached to the correct project and location instantly. No double entry. No retyping handwritten notes at the end of the day.

  • Integrated NOAA Weather Data

    Automatic connection to National Weather Service data supports proactive stormwater management by tying precipitation tracking directly to each project and its stormwater program requirements. Your inspection frequency and records reflect actual site conditions without manual research.

  • Centralized Dashboard Across All Projects

    Construction leaders see every active site, upcoming inspection, open corrective action, and deadline in one place, strengthening compliance tracking across the entire stormwater program. This visibility reduces missed inspections and strengthens accountability across crews and subcontractors.

  • Interactive Site Maps and Geolocation

    Update erosion controls, record geolocated findings, and maintain accurate site maps as conditions evolve. Your field teams can document exact locations of issues, corrective actions, and control measures directly from mobile devices. The result is clearer documentation and a more organized compliance program.

Frequently Asked Questions

  • What does SWPPP stand for in construction?

    SWPPP stands for Stormwater Pollution Prevention Plan. In construction, it outlines how a site will prevent sediment and pollutants from leaving the property through stormwater runoff.

  • What is a SWPPP inspection?

    A SWPPP inspection is a routine review of erosion controls, stormwater measures, and site conditions to confirm that the project is following permit requirements. Inspections are typically required weekly or after certain rain events, depending on the permit.

  • Do I need a SWPPP for my construction project?

    In most cases, projects that disturb one acre or more of land require coverage under a Construction General Permit, which includes developing and maintaining a SWPPP. Local requirements may vary, so it is important to confirm with your permitting authority.

  • What are common SWPPP mistakes on construction sites?

    Common SWPPP mistakes include incomplete or inconsistent inspection records and outdated site maps that do not reflect current field conditions. These gaps may seem minor at first, but they can quickly escalate during regulatory audits or site visits. Inaccurate or missing documentation increases the risk of violation notices.

    When documentation cannot show inspection frequency, precipitation records, or corrective action timelines, contractors may struggle to defend their compliance program.
