EWP & Crane Certification for Water Treatment
Inspection and certification of access and lifting plant used across water and wastewater treatment facilities, with attention to corrosive process environments.
Water and wastewater treatment plants use EWPs, cranes and hoists for maintenance of tanks, digesters, clarifiers and process equipment, frequently in corrosive and confined environments. Chlorine, hydrogen sulphide and constant moisture accelerate corrosion of access and lifting plant, while confined-space and depth access add operational complexity. EWP Certification Australia certifies water-sector plant to the applicable standards with particular attention to the corrosion and access challenges of the treatment environment.
Corrosion in the treatment environment
Process gases and constant humidity make treatment plants aggressively corrosive to steel structures, pins and welds. Overhead and gantry cranes over process areas, EWPs used for tank and structure access, and hoists all suffer accelerated degradation that regular inspection is essential to catch. Where corrosion is significant, non-destructive testing and structural assessment quantify remaining integrity rather than relying on appearance alone.
Standards for varied plant types
EWPs are inspected under AS 1418.10 and AS 2550.10, while overhead and gantry cranes fall under the applicable AS 1418 design references and the AS 2550 series for safe use, including periodic inspection and load testing after repair. We apply the correct scope to each plant type across the facility.
Access and confined-space considerations
Work in and around tanks, wet wells and digesters combines at-height and confined-space hazards. We plan inspections around the facility's access constraints and operational needs, keeping plant certified without disrupting continuous treatment operations.
