The schematic that stopped matching the building
Every site has an asset list somewhere: in the risk assessment appendix, on a schematic, in a spreadsheet, or in the monitoring template. It lists cold water storage tanks, calorifiers, sentinel outlets, showers, TMVs, little-used outlets, maybe expansion vessels and point-of-use heaters.
Then the building changes. A kitchen is refitted and two sinks are removed. A shower block is added. A calorifier is replaced with a plate heat exchanger. An outlet that was a sentinel is now in a storeroom behind shelving. The engineer notices and scribbles on the monitoring sheet, the risk assessor learns about it at the next review, and the monitoring template still asks for readings from a sink that no longer exists.
One building, four different lists
| List | Held by | Updated when |
|---|---|---|
| Risk assessment asset appendix | Assessor | At review |
| Monitoring template | Operations | When someone remembers |
| Sampling plan | Sampling lead | When a sample point fails |
| Client's own records | Facilities manager | Rarely |
Each list was accurate once. Because they are separate, a change reaches one or two of them and not the others, and engineers learn to ignore the parts that are wrong.
Living with a list nobody trusts
Engineers spend visit time working out which outlets on the template are real. Reports carry lines like 'outlet removed' month after month. Sampling plans point to outlets that have moved. Assessors walk into reviews blind to changes your own engineers saw months ago.
Clients notice too. A report that lists assets that do not exist makes the whole document look less careful than it is, and a facilities manager who spots one wrong line starts to doubt the rest.
One live register that every process reads
We replace the separate lists with a single register per site. Monitoring, sampling, TMV servicing and reporting all read from it.
- The register holds each asset with its type, location, identifier, photo and the tasks attached to it.
- Engineers see the register in their visit form and can mark an asset removed, moved or changed, or add a new one, with a photo.
- Changes go into a pending state and are sent to the office or the assessor to confirm, so the register does not change on one person's word.
- Completed remedial jobs that install or remove assets update the register automatically once signed off.
- Each change is logged with who, when and why, so the history of the building's water system is preserved.
- Changes that might affect the risk assessment are flagged to the assessor for their judgement.
If a client has schematics, we attach them to the site and can link assets to the drawing, but the register itself is the working record.
A register engineers stop working around
Monitoring templates are always current, because they are generated from the register. Sampling points refer to assets that exist. Assessors arrive at reviews with a list of changes since the last one, already documented with photos.
The office stops maintaining four lists. Clients see an accurate inventory of their own water system, which many of them have never had.
A typical day shows the difference. An engineer on a school visit finds that the science block sinks have been replaced during the summer. Instead of writing 'new sinks, see note' on a sheet, they update the three assets in the form with photos. The office confirms them the same afternoon, the assessor receives the change flag, and next month's template already shows the new sinks.
Check your registers against this
- Monitoring sheets list outlets that have been removed.
- Your asset list lives in several documents that disagree.
- Assessors find changes at review that engineers saw months earlier.
- Remedial works change the system without updating any list.
- Clients have no current inventory of their own water assets.
