Wastewater treatment works combine continuous wet exposure, biological residue, biogas-zoned hazardous areas, and outdoor structural-walkway conditions across the entire site — making PTV testing both highly relevant and operationally complex. Pendulum testing at WwTW sites requi…

Every wastewater treatment site has a distinct surface vocabulary that drives the testing protocol. We test the actual surfaces present, not a generic baseline.

Generic slip testing misses the zones that actually generate incidents. Wastewater Treatment sites have distinct high-risk zones that warrant independent testing.
Steel gratings over screening and grit-removal channels combine wet exposure with biological residue; PTV is consistently the lowest on site.
External walkways around primary and secondary clarifiers see continuous wind-borne moisture and seasonal algae.
ATEX-zoned biogas areas require intrinsically-safe testing equipment.
Sludge dewatering presses leak continuously; the floor surrounding is the highest-incident zone in most WwTW sites.
Wastewater treatment slip testing supports HSE INDG225, Workplace Regulations 1992 Reg 12, COSHH 2002 for biological and chemical exposure, DSEAR 2002 for biogas-zoned areas, and where applicable industry-specific water-sector H&S guidance from Water UK. UKAS ISO/IEC 17025 reports support compliance with the duty-holder's H&S management framework and the water company's Asset Standards documentation.
A Tier-2 water company commissioned annual UKAS pendulum testing across the inlet works, primary and secondary treatment, sludge handling, digester platforms, and chemical dosing building at a regional WwTW. ATEX-classified equipment was used for the digester gas-handling zone. The report integrates with the company's Asset Standards documentation framework as supporting evidence for slip-incident control.
