Attendance, shift and leave process for Sewage Treatment Companies: keeping the plant staffed through the night
A treatment plant has no closing time. The roster decides whether the person watching the tanks at three in the morning is rested, trained and actually there.

Share your requirementsWhy attendance, shift and leave process matters in sewage treatment companies
In many sewage plants the shift pattern lives in the in-charge's head. When one operator is absent, a phone call goes round, and whoever agrees stays on for a second shift. It works for a while. Then the same two people carry every gap, mistakes appear in dosing and logs, and one of them resigns without warning.
A written roster with named relievers and a limit on extended shifts removes the guesswork. It also gives you records to show a client that every shift was covered by a named, trained person, and to see which sites are always short.
How to set it up
1. Draw the shift pattern per plant
Write the shifts, the minimum people on each, and the tasks that must be done every shift. Keep one page per plant, signed by the plant in-charge.
2. Name relievers for each cluster
Pick trained operators who can cover nearby plants, and tell them in advance which sites they may be called to. Hold their leave planning together with the rest.
3. Set a limit on staying on
Agree how long anyone may extend a shift and how much rest must follow. The in-charge may refuse an extension on grounds of tiredness.
4. Record attendance at the plant
Use a register or phone entry by person and shift that reaches the head office daily. Match it with the client's own record each week, which also feeds pay processing.
5. Review gaps and overtime monthly
List the shifts that ran short, who covered them and total extra hours by person. Use this to decide where to hire.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Count shifts last month where fewer people than the roster said were present.
- List operators who worked two shifts back to back more than once, by name.
- Check whether leave is planned ahead for each plant or only agreed on the day.
- Compare your attendance record for one plant with the client's for the same week.

Questions owners ask
The plant in-charge approves within a leave plan set by the area manager, so relief is arranged before the date. Last-minute leave needs a named reliever, not a favour from a colleague.
Make overtime visible by person and site each month, rotate cover among trained relievers and hire for the sites that are always short. Repeated gaps are a headcount signal.
Use one rulebook and one format, but a roster for each plant. Differences in size, distance and client terms are listed as exceptions on the plant page.
