Strongford STW – GRP Odour Control Covers for Sludge Tank
Wastewater treatment – sludge tank odour control
This project involved the supply and installation of GRP walk-on odour control covers for a sludge tank at Strongford Sewage Treatment Works in Stoke-on-Trent, delivered for Severn Trent Water.
Project Overview
- Industry: Wastewater Treatment
- Location: Strongford STW, Stoke-on-Trent
- End Client: Severn Trent Water
- Project Scope: Sludge tank odour control
The installation required load-rated odour control covers suitable for a circular sludge tank, providing safe access while supporting effective containment within an operational wastewater treatment environment.
Project Requirements
The project required a walk-on cover system capable of spanning a circular sludge tank while maintaining safe access for inspection and maintenance activities.
Key requirements included:
- Odour control for a 9 m diameter sludge tank
- Walk-on access across the full tank area
- Defined load rating suitable for operational use
- Compatibility with a live wastewater treatment environment
Installed GRP Solution
PJNC supplied and installed GRP walk-on odour control covers designed to suit the tank geometry and site access requirements.
Installed systems included:
- GRP odour control covers: 70 m²
The covers were supplied as a walk-on system, providing safe access while supporting long-term durability and corrosion resistance.
Technical & Design Requirements
- Sludge tank diameter: 9 m
- Walk-on GRP covers rated to 5.0 kN/m²
All systems were designed to integrate with the existing tank structure while maintaining compliance with site safety requirements.
Installation & Delivery
Installation was carried out in a remote location, requiring consideration of access logistics, phased delivery and efficient on-site handling.
The modular nature of the GRP components allowed installation without heavy lifting equipment, supporting safe handling and installation within the constraints of the site.
Outcome & In-Service Performance
The completed installation provides effective odour containment across the sludge tank while maintaining safe, walk-on access for operational staff.
The GRP covers installed are well suited to the wastewater environment, supporting corrosion resistance and reduced maintenance requirements over the service life of the system.
