Access Steelwork for Water and Wastewater Treatment Works
Safe, permanent access is a requirement on every treatment site: operators need to reach tanks, channels, screens, pumps and valves for inspection, sampling and maintenance without working over open water or at height. Woodhams fabricates and installs the steelwork that provides that access, together with the support steelwork that carries process pipework – as part of a wider MEICA package or as a stand-alone steelwork package for a Tier 1 contractor or water company.
Walkways, bridges and platforms
- Modular access bridges and walkways spanning tanks and outlet channels
- Access platforms, stair towers, ladders, landings and self-closing safety gates
- Open-mesh flooring and mesh-infill handrailing
- Steelwork substructures supporting new process equipment inside existing tanks
Every structure is designed for the operational and maintenance access the site actually needs, and detailed to absorb the tolerances of existing concrete and pipework.
Pipe supports and pipe racks
- Bespoke pipe supports, brackets and hangers
- Elevated pipe racks for high-level process pipework
- Support frames for pump skids, distribution chambers and process equipment
Because we install the pipework as well, pipe routes, supports and access are coordinated before anything is fabricated.
Specification and compliance
- Designed to WIMES 9.02 for permanent access fabrications, including client-specific amendments such as Wessex Water’s DS 220 access and protection requirements
- Fabricated and erected to Execution Class 2 in accordance with BS EN 1090 (CE/UKCA marked)
- Hot-dip galvanised to BS EN ISO 1461 for long-term durability in wastewater environments
- Structural grades S275 and S355
- Fabrication drawings from our in-house design team where required
