This Sewer Work & Contamination Control SOP (Safe Operating Procedure) sets out how plumbers clear blockages, repair or replace sewer pipework and open inspection points, manholes and access chambers while controlling exposure to raw sewage. It covers isolating or diverting flow, PPE and hygiene, working from ground level, atmosphere testing, containing spills and decontaminating workers, tools and vehicles. It's written by WHS specialists, aligned to Australian WHS legislation, and fully editable in Microsoft Word.

Common questions
Does it cover entering manholes or pits?
No. Entering a pit, manhole or access chamber is confined space entry and needs your confined space entry procedure and permit. This SOP tells workers to stop if entry is required.
Does it cover operating jetters and drain machines?
No. Detailed operation of powered drain-clearing and jetting equipment is covered by plant-specific SOPs. This SOP covers the sewer work and contamination control around it.
What does it say about cuts and sewage exposure?
Workers cover cuts and grazes with a waterproof dressing before starting. If sewage contacts broken skin, eyes or mouth, they wash immediately and seek medical advice, telling the practitioner about the exposure.
Can I change it?
Yes. It's a Microsoft Word file, so you can add, remove or change any step, check or hazard, and add your own logo and details.
Does it suit my state?
Yes. It's written to the model WHS laws and suits all states and territories, including Victoria under the OHS Act and Regulations.
