A framework covering the supply of new screens and associated handling equipment, as well as the maintenance of all YW screening assets, and the hire of temporary screens and handling equipment. The framework has been divided into the following lots

• Lot 1: Supply of New Screens and Associated Spares for the direct supply of new screens and handling equipment to YWS, either when an existing asset requires replacement, or when a new capital scheme is identified. This covers all

types of screens, including those above and below ground.

• Lot 2: Reactive and Proactive Maintenance of Screens and Associated Equipment for the maintenance required for all above ground screens (all except CSOs), on a proactive basis and to reactively address issues.

• Lot 3: CSO Maintenance to cover the ongoing proactive and reactive maintenance of all CSO assets, including the screens contained within and any further maintenance required, e.g. chamber, throttle pipe, orifice plate, sluice, vortex, penstock, isolation valve, and outfall tasks.

• Lot 4: Asset Hire for the hire of screens and handling equipment on a temporary basis whilst a permanent asset is offline
