HUBER UK & Ireland: Successful Completion of a Stormwater Screening Solution at Ilkley Wastewater Treatment Works (England)
In May 2024, HUBER received the initial design order for a project at Ilkley from its client, Ward and Burke Construction Ltd, with Yorkshire Water as the end user. The full order was confirmed in October 2024 and included the supply, installation supervision, commissioning, and training for the following equipment:
- 2 x HUBER Storm Screen ROTAMAT® RoK1
- 2 x HUBER Lidded Trough Screw Conveyor Ro8 T
2 x HUBER Wash Press WAP® L 4
Extensive infrastructure project
A key component of the project was the design and construction of a 17,500 m³ storm tank to help the wastewater treatment plant to manage increased stormwater volumes. The proposed tank comprises dimensions of 135 m (L) x 25 m (W) x 5.2 m (average depth). The flushing chamber pockets comprise five chambers with the dimensions 1.8 m (L) x 4.9 m (W) x 2.975 m (D), providing an approximate flushing volume of 26 m³ per chamber. As part of the scope of works, Ward and Burke engaged HUBER to provide a stormwater screening solution to remove screenings from the incoming flow prior to entry into the tank. Influent flows are screened using the HUBER Storm Screens ROTAMAT® RoK1. The anticipated peak flow is 3,500 l/s, with each screen sized to handle 1,834 l/s, providing a combined capacity of 3,668 l/s.
From the outset, it was clear that this would be a complex undertaking. Over the following months, the design phase required extensive collaboration with the client, with numerous revisions and discussions to address site constraints, operational requirements, and proposed design changes for both the storm tank and the HUBER equipment.
HUBER’s proposed solution was two Storm Screens ROTAMAT® RoK1 500/6 9.375 mm 0°, each capable of passing a spill flow of 1,834 l/s. They feed into their own separate Screw Conveyors Ro8 T with a length of 7.200 mm. Each conveyor is capable of processing 4.0 m³/h. The conveyors feed into their own separate Wash Press WAP® L4, which has been designed to provide efficient separation of organic material from sewage screenings with subsequent screenings, compaction and dewatering, prior to discharge into the skip. Each Wash Press can process up to 4.0 m³/h.
Successful delivery and commissioning
Production was released in January 2025, and once the machines were delivered from Germany, the HUBER UK workshop team completed the final assembly works. All equipment was then delivered to site in a single shipment in June 2025, with installation supervision carried out at the same time. Due to the scale of the site and the ongoing civil works, the installation phase progressed over an extended period while the site works were being completed. Ward and Burke successfully completed the installation, and HUBER commissioning was finalized in February 2026.
This was another highly interesting project from design concept to full operation, helping to make our “water world” cleaner and more sustainable. Overall, this was a successful project delivering multiple HUBER machines, and we are very pleased with the outcome. Special thanks go to our Northern regional team for their continued support throughout the site activities.
