SW² is a vertical SaaS platform for stormwater compliance management, serving construction teams, municipalities, industrial facilities, and consultants. It brings field inspections, SWPPP/SWP documents, site maps, weather data, photos, corrective actions, and reports into one real-time system. The goal is to reduce paper records and duplicate data entry, while keeping project documentation complete ahead of audits or regulatory inspections.
Based on the available information, SW² covers the full “inspect—record—report—audit” workflow. It supports customizable checklists, inspection calendars, corrective action (CA) logs and notifications, photo annotations, and geolocation. On the document side, it offers unlimited document storage, project folders, editable SWP documents, change/revision tracking, and activity logs. Mapping features include satellite imagery, interactive site maps, BMP icons, and real-time map updates. The weather module integrates with NOAA/National Weather Service, providing forecasts, rainfall data, weather tables, and automatic rain logs. For reporting, it supports custom reports, multi-site reports, CSV/Excel/PDF exports, and KPI dashboards.
Plans are Essentials, Pro, and Enterprise, starting at $12, $18, and $49 per month respectively. Essentials and Pro are marked as offering a free trial, while Enterprise requires contacting the company for pricing. The site emphasizes no hidden fees, monthly renewal or plan changes, and the ability to add features as needed. Deployment is cloud-based SaaS, with support for PC, iOS/Mac OS, mobile phones, tablets, and desktops. An offline mode is also available, which is useful for fieldwork on job sites with unreliable connectivity.
The team features are fairly complete, including unlimited users, organization by company/region/department/site, customer-managed site and user creation, role-based access, and personalized views. It also supports sign-off without login and QR Code read-only document access. On security, SW² discloses daily backups, SSL, 256-bit encryption, audit trails, and document activity logs, but there is no visible mention of certifications such as SOC 2 or ISO 27001. Integrations mainly cover NOAA/NWS weather and Google Maps route planning; API or developer support is not disclosed.
Its strengths are its highly focused use case, tight integration of field inspections, maps, rainfall data, and compliance reporting, plus a relatively low entry price. The main limitations are its clear focus on U.S. regulations and the NOAA data ecosystem, meaning suitability for China or other non-U.S. markets would need to be validated. API availability, payment methods, SLA terms, and security certifications are also insufficiently disclosed. SW² is best suited for U.S. construction sites, industrial facilities, municipal departments, and environmental compliance consulting firms that need multi-site stormwater inspections, SWPPP maintenance, and audit preparation.
Access from China is unknown. Because SW² depends on overseas services such as Google Maps and NOAA, even if the main website is reachable, maps, weather data, or the mobile experience may be affected by network conditions. Payment methods are not disclosed. For Chinese users who only need local inspections, environmental compliance records, or construction compliance management, domestic EHS platforms, construction project management tools, inspection form systems, or low-code platforms may be better alternatives.
