Streamline your stormwater compliance with digital inspections, reporting, and real-time tracking.
SW² offers stormwater inspection software that connects National Pollutant Discharge Elimination System (NPDES) inspections, Stormwater Pollution Prevention Plan (SWPPP) documentation, Municipal Separate Storm Sewer System (MS4) programs, and industrial stormwater workflows in one system.
Field teams can record findings on-site while office staff review maps, documents, corrective actions, and reports from the same project record. That shared visibility helps teams stay organized, respond faster, and keep audit-ready documentation within reach.
Stormwater inspection software gives compliance teams one place to record site conditions, document findings, and build reports for NPDES requirements. It replaces the mix of paper forms, spreadsheets, marked-up maps, and photos stored across different devices.
With SW², field inspections stay connected to the right project, map, SWPPP file, and follow-up record from the start. Construction teams, MS4 programs, and industrial facilities can pull together a cleaner audit trail without rebuilding the history later.
Book a DemoStormwater inspection software serves teams responsible for collecting field data, maintaining permit records, resolving findings, and proving compliance across one site or an entire program.
Construction inspectors use SW² to document changing site conditions, inspect best management practices (BMPs), record rain-event impacts, and keep corrective actions moving as work progresses.
Municipal teams use the platform to manage inspections, assets, program records, and reporting across departments, contractors, outfalls, inlets, and other regulated locations.
Industrial compliance teams can organize facility inspections, monitoring records, permit documentation, findings, and corrective actions without relying on disconnected systems.
Consultants use SW² to separate client records, standardize inspection workflows, manage multiple projects, and generate consistent reports without rebuilding each process from scratch.
SW² supports NPDES-based inspection and reporting workflows across construction, municipal, and industrial stormwater programs. Each workflow can reflect the permit, inspection schedule, site conditions, and records the team needs to manage.
The sections below explain how those needs differ across major permit programs.
Construction SWPPP inspections focus on changing site conditions, BMP performance, and erosion and sediment controls. Because the site shifts as work progresses, inspectors need a simple way to document what they saw and track fixes.
Common tasks include:
MS4 workflows follow minimum control measures and program requirements across a city or county rather than one project. SW² helps teams organize asset-based inspections, program records, and annual reporting across the jurisdiction.
Typical modules include:
Industrial workflows vary by permit and facility, so it is smart to verify the details locally. In practice, many programs combine routine walkthrough inspections with documentation and, when required, monitoring or sampling records.
Common tasks include:
Digital SWPPP inspections reduce the gap between what an inspector sees in the field and what appears in the final compliance record. With SW², inspectors can collect findings from a phone or tablet and keep the inspection tied to the right project from the start.
Field teams can:
Good SWPPP software does more than digitize a checklist. It keeps the inspection record, current plan documents, site conditions, and reporting history aligned as the project changes.
Rain conditions can change inspection schedules quickly, especially when teams manage several active projects. SW² brings weather information and rain-event documentation closer to the inspection workflow, so staff do not have to rely on a separate forecast tab, spreadsheet, or email chain.
Depending on the plan and configured tools, teams can use weather data to:
The main value is not the forecast alone. It is the connection between weather, the inspection schedule, the site record, and the final compliance report.

Corrective action tracking starts while the inspector is still walking the site. SW² helps field teams document the issue, capture its location, and begin drafting the inspection report without repeating the same work later at the office.
Capturing the information once, at the point of inspection, reduces repeat data entry and helps both field and office teams work more efficiently.
Book a DemoThe best stormwater compliance software for your team is the one that works under real field conditions and still gives supervisors clean, defensible records. A polished demo matters less than what happens when an inspector has poor service, several findings, and a report due the same day.
Use these seven criteria when comparing platforms:
Before making a larger commitment, test the software on one active project. Complete an inspection, attach findings, close a corrective action, update a site map, and export a report. That short pilot will reveal more than a long feature list.

Moving a compliance program into new software takes more than sending users a login. SW² provides onboarding, guidance documents, and continued training through its customer experience portals, helping field inspectors, administrators, and supervisors learn the parts of the platform they use.
Resources cover areas such as project setup, inspections, maps, documents, reporting, and corrective action workflows. As teams add projects or adjust their compliance process, they can return to the portal for continued guidance instead of relying on a one-time introduction.
