In plain English
Yorkshire Water needs a specialist maintenance partner to look after their ozone treatment systems across multiple water treatment sites. The work covers planned maintenance, emergency repairs, parts management, equipment upgrades, and minor capital improvements to ozone plants and related equipment.
What the buyer wants
• Provide planned and reactive maintenance on ozone-generation systems, including inspections, fault diagnosis and breakdown repairs • Manage spare parts inventory, deal with obsolete equipment, and carry out equipment replacements and refurbishment • Deliver mechanical, electrical, instrumentation and control systems work, plus testing, commissioning and performance validation • Provide emergency response capability and technical support, along with maintenance documentation and asset data
Likely requirements
Our reading of the notice. Always check the tender documents.
This is a highly specialized contract requiring proven expertise in ozone water treatment systems, electrical and instrumentation work, and critical infrastructure maintenance. Most general tradespersons without specific ozone plant experience or relevant water industry background will not meet the technical capability bar. The estimated contract value (£216m+) also suggests this framework is designed for established multi-disciplinary engineering firms, not sole traders or small local businesses.
How to bid
This is a framework: the buyer picks a set of suppliers now and awards work to them over several years. If you are not on it when it is awarded, you usually cannot win work from it until it is re-tendered, so this is the window to bid.
