Manchester Trunk UID - Salford - Buffalo Court

Category: General

The Galliford Try, Costain, Atkins (GCA) Joint Venture are currently working on behalf of United Utilities (UU) at Buffalo Court in Salford, Manchester.  As part of this main contract Franklyn Yates Engineering have been awarded the mechanical works as described below.


Brief Outline of the Project

The project briefly comprises the following elements: -

  • Screening of spill flows up to and including a 1 in 5 year storm event from both the SAL0071 and SAL0172 CSO Diversion chamber and connection channels to direct flows into and out of the detention tank

  • Provision of 1 No. 4,500m3 detention tank storage downstream of the CSO's prior to the outfall into the Manchester Ship Canal

  • Automated detention tank screen wash system

  • Automated detention tank base cleaning system

  • Automated transfer and scavenger pumps together with associated rising mains to empty the detention tank

Scope of Works & Responsibilities

The Works consist of the design, specification, manufacture, supply, un/witnessed works inspection and testing, delivery, off-loading, secure storage, on-site materials / equipment handling and lifting, positioning, installation, valve tagging, equipment asset labelling, pipework banding, lagging / cladding banding, on-site testing and commissioning and ‘as-built’ drawings of all installed equipment (and marked up ‘for construction’ drawings indicating as-built changes) of all necessary equipment to provide the complete Mechanical Installation at each work face.
