Tradie Forms: complete the QLD Form 11 treatment plant service report while the plant, owner, readings and service notes are still in front of you. Fill guided sections, catch missing fields, preview the official PDF layout and download the finished report for local government, the owner and the job record.
QLD Form 11 is one of those reports that looks quick until you are back in the ute trying to remember plant details, readings, alarm status and the owner's email. The service itself may be done, but the report still needs to be clear enough for local government, the owner and your own records.
This guide is for Queensland plumbers and service technicians completing the service report for an on-site sewerage treatment plant or greywater treatment plant. Use the QLD Form 11 template to map your entries onto the official PDF layout, or browse QLD plumbing forms for related permit, testing, backflow and handover paperwork.
Tradie Forms helps you fill the official layout cleanly. It does not decide whether the plant is functioning correctly, whether maintenance has been done properly, or whether further work is needed. The licensed person and service technician remain responsible for checking the work and the exported PDF.
What QLD Form 11 is for
The Business Queensland forms page lists Form 11 as the service report for a treatment plant under the Plumbing and Drainage Act 2018 forms set. The official Form 11 PDF says it is used for the purposes of section 106 of the Plumbing and Drainage Regulation 2019.
The official PDF also says the form must be submitted to local government and a copy provided to the owner of the facility within 10 business days after servicing the facility.
In plain English, Form 11 is the service record for an on-site sewerage or greywater treatment plant. It captures the site, plant, status, land application area, service tests, annual tests if applicable, owner details, technician details and declaration.
It is not the original permit application. It is not the treatment plant approval. It is the service report after the service visit.
Why complete it while you are still on site
A treatment plant service has more details than most people want to keep in their head. If you wait until later, small gaps become guesswork.
The on-site moment gives you:
- The actual plant brand, model and serial number
- The plant status you observed
- Land application area condition
- Test readings and alarm checks
- Arrival and departure times
- Owner details if they are present
- Photos and notes while access panels are still open
- The chance to explain defects or follow-up work to the owner
That is the best time to fill the report. If something is not functioning correctly, write a detailed description while you are looking at it. If the system needs de-sludging, record it clearly. If the irrigation field could not be located, do not leave the field blank and hope the office works it out.
Property and treatment plant details
Form 11 starts with the land and the treatment plant. The land description should identify the property. Include the street address, lot and plan, local government area and local government reference number where applicable.
The treatment plant section asks whether the report is for an on-site sewerage treatment plant or a greywater treatment plant. It also asks for brand, model and serial number.
Do not rely on what the job was booked as. Check the plate, service history, owner documents or previous report where available. A wrong model or serial number can make the report harder to match to the asset later.
Business Queensland's on-site sewage facilities guidance says installing an on-site sewage treatment plant requires local government approval and treatment plant approval under the Plumbing and Drainage Act 2018. Those approvals are not the same thing as the Form 11 service report, but they are part of the wider treatment plant record.
Plant status
The plant status section asks whether the treatment plant is functioning correctly and whether system de-sludge is required.
This is a simple section, but it has weight. If the answer is no, the official PDF asks for a detailed description. A few clear words on site are better than a vague note later.
Useful notes might cover:
- Pump not operating
- Audible or visual alarm issue
- High sludge level
- Effluent leaving premises
- Land application area not functioning correctly
- Owner advised of follow-up work
- Manufacturer procedure not completed and why
Do not overclaim. If you have not diagnosed the cause, say what you observed. The report should be a true and accurate record of the service visit.
Land application area
Form 11 asks about the disposal method and land application area. It includes options such as surface or spray, subsurface, covered surface, trench and other. It also asks whether the irrigation field was located, whether effluent is leaving the premises and whether the land application area is functioning correctly.
These are easy fields to skip if access is awkward or the owner is in a hurry. They are also the fields that help explain whether the treated effluent side of the system is behaving as expected.
If the land application area is not functioning correctly, the official form asks for a detailed description. Write the issue in ordinary site language. If photos help the office or owner understand the problem, store them with the job record.
Tests every service
The official Form 11 includes tests to be completed every service if applicable. It provides fields for pH, residual chlorine, clarity, temperature, air blower filter status, pump working, audible alarm working, visual alarm working and chlorine tablets added.
The phrase "if applicable" matters. Some systems and service procedures differ. Follow the system requirements and manufacturer procedures. Where a field applies, record the result rather than leaving it to memory.
Tradie Forms makes the testing section easier to work through on a phone. The goal is not to turn the service into desk work. It is to capture the readings once, in the right section, so the PDF is ready for handover.
Annual tests
Form 11 also includes annual testing fields if applicable: primary tank sludge test, secondary tank sludge test and air blower back pressure test.
If this is an annual service, have the equipment and previous record ready before the job. If annual testing does not apply to the service visit, do not fill a number just to make the form look complete.
The better habit is to store the Form 11 PDF beside the job history. Then the next service technician can see what was recorded last time and whether any follow-up was noted.
Service procedure
The official form asks whether the service has been completed in accordance with the manufacturer's operation and maintenance recommended procedures. It notes that service technicians can access the recommended maintenance procedures from the particular manufacturer.
This is where field notes matter. If the answer is yes, the job record should make sense. If the answer is no, the reason should not be hidden. Maybe access was blocked, a component needed replacement, the owner declined work, or a follow-up visit was needed.
Tradie Forms can keep the procedure answer and job notes together, but the technician still needs to make the judgement honestly.
Owner and technician details
Owner details should be current. If the property manager booked the job but the facility owner must receive the copy, check which details belong in the report.
Technician details should include the service date, arrival time, departure time, minutes on site, company or individual name, service technician name and licence number. These details are easy to repeat across jobs, so saved licence and business details help. Check them before export when staff, licence or company details change.
The declaration says the information provided is a true and accurate record. Treat the PDF preview as the last check before it goes to local government or the owner.
Common Form 11 mistakes
Missing the serial number
Brand and model help, but the serial number identifies the unit. Capture it from the plant or reliable records.
Using vague fault notes
"Not working" is not enough if the owner, local government or next technician needs to understand the issue. Write what you observed.
Forgetting owner copy
The official PDF says a copy must be provided to the owner within 10 business days after servicing the facility. Build that into the workflow.
Skipping land application details
The plant may run, but the land application area still matters. Record the disposal method and status.
Leaving the report outside the job record
The Form 11 PDF should sit with service notes, photos, owner communications and any quotes or follow-up work. A clean record helps the next visit.
How Tradie Forms helps
Tradie Forms turns QLD Form 11 into guided sections for property, treatment plant details, plant status, land application, service tests, annual tests, service procedure, owner, technician and declaration.
You can save owner and technician details, catch missing fields before export, preview the official PDF layout, download the finished report, and attach or store it with the job record. That is especially useful for businesses servicing multiple treatment plants each week.
Related Queensland plumbing forms include QLD Form 1 for permit applications involving on-site sewerage work, QLD Form 2 if treatment plant details change under an existing permit, and QLD Form 5 for testing or commissioning reports.
