Hydraclean is a UK-based water hygiene and compliance provider serving corporate infrastructure across multiple sectors.
Under UK regulations, organisations must conduct annual Legionella risk assessments across all water systems, including taps, tanks, pipework, thermostatic mixing valves (TMVs), and air conditioning units. These assessments ensure safe water temperatures, prevent stagnation, identify “dead legs” in pipework, and mitigate bacterial growth risks.
For large commercial buildings, this can mean inspecting and documenting thousands of individual data points.
The challenge: A complex process trapped on paper
Hydraclean’s engineers followed a thorough but manual process:
- Visiting sites physically
- Moving room-to-room, outlet-to-outlet
- Recording temperatures and risk factors on paper forms
- Identifying unused outlets, stagnation risks, and dead legs
- Inspecting tanks, main supplies, geysers, and connected systems
- Classifying risk levels (low, medium, high)
For a single 100-room building, this could generate hundreds of pages of documentation.
Once inspections were complete, the real bottleneck began:
- Paper forms had to be transcribed
- Data had to be collated
- Risks analysed against UK regulatory guidelines
- Reports manually structured and formatted
- Historical logs and compliance notes reviewed
The result:
- Long report turnaround times
- Administrative backlog
- Data sitting outside the central system
- Increased operational strain
As Hydraclean grew, this approach became increasingly unsustainable.
The vision: A digital, intelligent compliance ecosystem
Hydraclean already had a web portal and mobile application for managing clients and tasks. However, inspection data collection and reporting still relied heavily on manual processes.
Imobisoft’s goal was not just to digitise forms, but to redesign the entire risk assessment lifecycle.
The solution
1. Mobile-first digital inspections
Imobisoft converted Hydraclean’s complex, regulation-driven paper forms into structured digital workflows integrated directly into their mobile application.
Now:
- Clients and sites are created in the web portal
- Legionella risk assessment tasks are assigned
- Engineers receive tasks via tablet/mobile
- All inspection data is captured digitally in real time
Engineers can:
- Record temperatures instantly
- Catalogue outlets and endpoints
- Flag dead legs
- Log TMV conditions
- Document tank and supply relationships
- Categorise risks within structured fields
No printing. No transcription. No disconnected paperwork.
Infrastructure relationship mapping
Water systems are not linear.
Main supply lines feed into tanks. Tanks connect to heaters. Systems branch into multiple endpoints. Components overlap.
Imobisoft built a system capable of modelling these complex relationships accurately — ensuring every inspection point is contextually mapped within the broader infrastructure.
This was critical for regulatory traceability and audit readiness.
AI-powered risk assessment & report generation
The most transformative element was introducing AI into the reporting workflow.
Once an engineer completes an inspection:
- Structured data syncs automatically
- AI analyses risk factors
- Temperature ranges are evaluated
- Stagnation and bacterial growth risks are assessed
- Findings are compared against regulatory guidance
- A structured Legionella Risk Assessment report is generated
What previously required extensive manual drafting is now produced in minutes.
Human-in-the-loop governance
Because this is compliance-critical work, accuracy is non-negotiable.
Imobisoft implemented a human-in-the-loop model:
- AI generates the draft report
- A compliance specialist reviews and edits
- Final approval ensures regulatory alignment
This balances efficiency with professional oversight.
Future-proof regulatory architecture
Regulations evolve.
Imobisoft designed the system to be flexible:
- Assessment logic can be updated
- Regulatory thresholds can be modified
- Report formats can adapt
This ensures Hydraclean remains compliant even as legislation changes.
The Impact
Operational efficiency
- Eliminated paper-based inspections
- Reduced administrative workload
- Significantly shortened report turnaround times
Scalability
- Faster processing of large, multi-site clients
- Increased assessment capacity
- Reduced backlog
Compliance confidence
- Structured, auditable digital records
- Standardised risk evaluation
- Human-reviewed AI reports
Digital transformation
Hydraclean moved from:
Manual inspection → Paper collation → Reporting backlog
To:
Digital inspection → Structured data → AI-generated reports → Human-verified compliance
Strategic outcome
Hydraclean now operates with:
- A scalable digital compliance platform
- AI-augmented reporting capability
- Improved operational agility
- Reduced administrative friction
- Stronger regulatory governance
For Imobisoft, the project demonstrates how intelligent digital infrastructure can modernise even the most regulation-heavy industries, blending operational precision with AI innovation.
