Cooling tower inspection app for water treatment firms
Cooling towers are the best-known source of Legionella outbreaks, so the water treatment contractor’s monthly visit is regulated in most states: the system must be registered, run under a risk management plan, sampled for Legionella and heterotrophic colony count, and kept clean. The service report records the tower’s physical condition, dosing, water chemistry and lab results, and has to say clearly when a result triggers a response.
Built for water treatment firms running teams of roughly 3–50 inspectors.

Tower registration report
Cooling water system CWS-1 — monthly service
- Site
- Fictional Hospital, plant room L10
- Towers
- CT-1, CT-2 (registered system)
- Service date
- 9 June 2026
| Check | Result | Status |
|---|---|---|
| Drift eliminators | In place, no gaps or damage | Status: Pass |
| Basin condition | Light sludge in CT-2 basin | Status: Clean due |
| Biocide dosing | Pump operating; drum 40% full | Status: Pass |
| Legionella (sample 12 May) | < 10 cfu/mL | Status: Not detected |
| HCC (sample 12 May) | 2 × 10⁵ cfu/mL | Status: Above action level |
Fields captured on site
Your firm builds the form in-app, so these are a starting point rather than a fixed schema. Every field is captured on the device, with or without signal, and lands in the tower registration report where your template puts it.
Per tower
- Tower ID
- Drift eliminators condition
- Basin and fill condition
- Water make-up and bleed operating
- Photos
Water treatment
- Biocide and inhibitor dosing
- Conductivity
- pH
- Chemical stock levels
Sampling
- Sample date and point
- Legionella result
- HCC result
- Exceeds plan action level (yes / no)
- Corrective action taken
Standards the report works to
- AS/NZS 3666.2Air-handling and water systems of buildings — Microbial control — Operation and maintenance
- The routine inspection, cleaning and maintenance the monthly report confirms.
- AS/NZS 3666.3Air-handling and water systems of buildings — Microbial control — Performance-based maintenance of cooling water systems
- The basis for the sampling regime and the action levels a result is reported against.
- Public Health Regulation 2022 (NSW)Regulated systems — cooling water systems
- For NSW sites: registration, risk management plan and reporting obligations the service supports.
Load the standards you hold into your reference library and the drafted prose is written against them rather than against a general model.
How the tower registration report gets built
Capture it once, offline
Your firm builds the cooling tower inspection form in-app — 25 field types, nesting repeatable groups, compound AND/OR visibility rules, reusable modules and calculated fields. Field capture works with no signal: jobs, forms, photos, notes and audio all queue in an idempotent outbox that only clears once the server confirms receipt.
Link it to your buildings, levels and tenancies
Enter buildings, levels and tenancies once, as a register. Every one of your elements, defects and cost lines then points at a stored row rather than a name somebody typed — and the links survive a disconnected device.
Render your own template
The tower registration report renders into the Word template you already use — your letterhead, your section order, your clause library — with conditionals, loops over repeats, composable sub-templates and photo grids.
Reviewed before it leaves
You write the review framework: a checklist of what a tower registration report must contain, plus the prose standards you would mark a junior against. Link it to a report template and it runs every time that template renders. Each finding comes back graded info, minor or major, quoting the sentence at fault, and a person accepts or dismisses every one.
Because the structured submission behind the report is held too, the review is a comparison rather than a proofread: The narrative calls the roof "fair"; the element register grades it C with a twelve-month cost line against it.
Checks a commercial property framework usually carries
- Every graded defect carries a cost band and a priority
- The make-good schedule and the narrative describe the same condition
- Access and DDA non-compliances cite the clause they fail
- Every photo referenced in the text exists and is captioned
Questions
- Can lab results be added after the site visit?
- Yes. The submission can be edited when the lab report arrives, and the report is rendered after that so the results land in the same document as the inspection.
- Can the report flag a result over our action level?
- Action levels can be built into the form as visibility rules or calculated checks, so an exceedance reveals the corrective action questions and the template can highlight it.
- Can we schedule monthly visits automatically?
- Recurring jobs repeat on a fixed rule, so each registered system can carry its own monthly service without being booked by hand.
What this is not
Worth knowing before you book a demo, so neither of us wastes the half hour.
- Not field-service dispatch. No timesheets, no parts, no inventory. Scheduling exists to get an inspector to a site.
- No signature capture. If your deliverable has to carry a signed sign-off on the artefact itself, this is not the tool yet.
- Field capture is what works offline — jobs, forms, photos, notes and audio. Reports, chat, scheduling and the inbox need a connection.
- No client portal. Reports go out as a file or a password-protected link.
