• Lab coordination (as required): Collect water samples for accredited microbiological testing; submit results to client.

• HSE compliance: Follow confined-space protocol (gas testing/ventilation/standby), chemical-handling SOPs, PPE use, ladder/work-at-height safety, and heat-stress controls.

• Client communication: Explain scope, variations (heavy sludge, damaged fittings), and post-service hygiene advice; protect surrounding areas and ensure tidy handover.
