About Acutro WM

Acutro WM provides water quality monitoring and compliance services for commercial buildings, hospitals and industrial facilities.

The challenge

What needed solving

Water quality management is compliance-heavy and highly specialised: engineers sampling in the field, labs processing results, assets spread across hundreds of sites, and strict regulatory requirements. Acutro was running all of it on spreadsheets and disconnected tools.

The hardest part was the domain itself - specialist terminology, regulatory constraints and operational edge cases, with little structured input up front. Someone had to model it.

We didn’t wait to be told what to build. We understood the domain and drove the architecture ourselves.

The solution

What we built

A three-person 2C team built the whole system from the ground up, in direct contact with the client. We took the time to understand water compliance properly, then turned its workflows into a structured system - designing the architecture, the domain model and the frontend ourselves, with minimal hand-holding.

The backend is a modular monolith in Node.js and Express on MongoDB, with clear domain modules, a dedicated authentication layer and audit logging. Managers, labs and clients use a React web app; field engineers use a React Native mobile app.

  • Hierarchical model: clients → sites → systems → assets → tasks
  • QR codes that link physical assets to their digital records
  • Mobile task lists for field engineers, with sampling records and uploads
  • Lab results recorded against systems and assets
  • Role-based access for engineers, labs and clients
  • Audit logging and soft deletes for compliance traceability
The result

What changed

  • Spreadsheets replaced by one operational platform

  • Less manual coordination, faster scheduling and reporting

  • Compliance traceability in one place

  • The operational backbone across hundreds of sites

  • Ready for automated compliance evaluation and lab integrations
