Gee & Co participated in the delivery of the first AMP6 project for Severn Trent Water, where we manufactured the chemical dosing plant.

Gee & Company of Birmingham are delighted to announce the award of a framework for Chemical dosing systems for United Utilities. The award is for a period of 5 years, and contains a discretionary extension up to 7 years. This framework covers both chemical dosing skids themselves, and packaged chemical dosing systems, built at Gee’s 6 acre Birmingham design & manufacturing facility.
The process was initiated, post to a UU review of the quality of chemical dosing installed asset base from AMP 5. This resulted in UU approved strategy of a move towards fixed standard configurations, consisting of 3 types of dosing rigs, and 3 tank sizes, for all new chemical dosing equipment. This in turn was aligned to Design for Manufacture & Assembly (DfMA) that also meet or exceed the UU asset and engineering standards. Ultimately the project specific requirements can call from the most appropriate dosing rig or packaged plant size, to ensure the continuity of standardisation and build quality, across all UU water & wastewater sites.
This procurement process took a great deal of time and effort on the part of both parties. The UU team comprising of Procurement, Mechanical, Electrical and Maintenance representatives, adopted a standard based design layout, after consideration of historic good practise, including the Sodium Hydroxide dosing skids Gee originally supplied at UU’s Sweetloves WTW. To ensure due diligence within this procurement process, UU undertook bidder workshop site visits, whereby Gee’s were required to build a range of replica dosing skids, to the signature design standard & specifications, thus enabling the UU team to audit adherence & build quality.
Matt Walker a Senior Buyer at UU said ”It is essential that standardised chemical dosing systems are selected, to drive optimum performance with lowest whole life cost, to achieve the key business needs of operability, affordability, and being technically acceptable. This, aligned with enabling UU to maintain the equipment in a safe and reliable condition, allows UU to maintain it’s reputation as one of the UK’s leading Water & Wastewater companies”.
This procurement process for chemical dosing equipment proved a success, and has since evoked the beginning of discussions on design improvements at a subsequent working group, to which Gee’s are able to give further developmental design input to. Gee have a full manufacturing capability for packaged and conventional dosing systems, including an in-house full M&E design and contract management department, thermoplastic tank manufacture, plastic & steel fabrications, as well as a large general assembly and test facility that has served UU well in the past, and is well suited for UU’s current plans and beyond. Gee’s are also well placed to serve UU with respect to their existing and future assets with their own specialist site staff, comprising of Commissioning, software, mechanical and survey engineers, enabling a chemical dosing system to go from design to completion, with total control I house, and no need for other sub-contractors. This has made Gee & Company the UK leader in the supply of chemical dosing systems to the water utilities.
Mark Shepperson – Sales Director at Gee & Company said “We are delighted to be supporting such a leading water utility such as United Utilities. We echo their sentiments with respect to the need for standardisation, and ensuring quality and maintainability of critical chemical dosing systems. We also relish the opportunity to technically support UU and their Construction Delivery Partners, in the future”.
Pic 1 = Installation of tanks at UU’s Sweetloves WTW
Pic 2 = UU skid build as part of audit process
Pic 3 = Packaged Plant Installed at UU’s Royton STW
PIC 1 – Caustic tank insertion at UU’s Sweetloves WTW – The tank was manufactured and insulated by Gee’s, the tanks were then righted once within the building, and ultimately connected to the Gee dosing skids.
PIC 2 – UU skid build as part of audit process – The brief was detailed, with stipulations such as no fixings on the back of skid, no internal trunking, removable catchpots & calibration vessels, also a removable top box, for secondary containment access, and even an A3 document holder.
PIC 3 – Packaged Chemical Dosing plant at UU’s Royton STW – The chemical was Kalic, a liquid lime product, acting as an alkalinity donor. This package utilised tank mixing, and peristaltic pumps, and with an extended separate electrical kiosk, housing a framework full form 4 control panel.
