Weekly readings from two different teams
Clients with evaporative cooling towers or condensers have a heavier record-keeping load than most. There are weekly checks and readings, chemical dosing records, dip slides that are incubated and read later, bleed and conductivity figures, and periodic lab samples. Some of it is done by your engineers on service visits. Some is done by the client's own maintenance team between visits.
The records come back in every form imaginable: your engineer's sheet, a site technician's notebook photographed on a phone, a dosing controller's printout, a dip slide result written on a sticky note. Your water treatment specialist is meant to review them, spot trends and advise the client, but first they have to gather them.
Why weekly records are harder than monthly ones
| Record | Who records it | Usual problem |
|---|---|---|
| Weekly system checks | Site staff or engineer | Missed weeks, different formats |
| Dip slide reading | Whoever set it, days later | Forgotten, or result not linked to date set |
| Dosing and chemical use | Controller or engineer | Printout never sent |
| Lab sample results | Laboratory | Separate from weekly records |
| Actions taken | Various | Written in margins |
Weekly frequency means small gaps appear constantly, and the split between your team and the client's team means nobody owns the whole picture.
What scattered records cost
Your specialist spends their expertise on collecting paper rather than interpreting it. Trends that would be obvious on a chart go unseen across separate sheets. Missed weeks are discovered late, and the client may not realise they are responsible for some of the gaps.
When the client or an inspector asks for the records, assembling them is a job in itself.
Weekly capture for both teams, one review queue
- Each cooling system is set up with the readings and checks your programme specifies, and who is responsible for each: your engineer or the client's staff.
- Both teams record through the same simple mobile form, so the format is always the same. Client staff do not need a full login, just a secure link per system.
- When a dip slide is set, the form schedules a reminder to read it, and the result is linked back to the date it was set.
- Where dosing controllers can export data, we import it. Otherwise engineers photograph the display and enter the key figures.
- Lab results for the system arrive from the sample register and sit alongside the weekly readings.
- Each week's record goes into a review queue for your specialist, with values outside the ranges you set highlighted and missed readings listed.
Trend charts per system show conductivity, dosing, dip slide results and lab results over time, which is far easier to review than a stack of sheets.
What the specialist's week looks like
On Monday, your specialist opens the queue and sees last week's records for every system, with anything unusual already highlighted. Missing entries from client staff produce an automatic reminder to the site. Their comments and any advice to the client are recorded against the week.
Clients get a clear weekly or monthly summary, and can see which records are theirs to complete.
When the client's maintenance technician goes on holiday, the missing weekly entries show up the same week, not at the next quarterly review. The client can arrange cover while it still matters, and the record shows exactly which weeks were affected. When your specialist changes, the new person inherits a complete history per system rather than a filing cabinet.
The records are also far easier to produce on request. A client asking for the last year of records for one cooling tower gets an export with every weekly entry, dip slide result, lab result and review comment in date order.
Are cooling records a struggle?
- Weekly readings arrive in different formats from different people.
- Dip slide results are sometimes never recorded.
- Dosing controller data is not collected routinely.
- Your specialist spends time chasing records rather than reviewing them.
- Trends are hard to see because records are on separate sheets.
