Summary of the contracting process

Scottish Water is currently in the tender stage of a procurement process for the "Odour Treatment & Control" project. This involves the surveying, design, manufacturing, delivery, installation, commissioning, and testing of odour control and treatment plant and equipment, along with related ventilation systems. The procurement has a value of £6,000,000 and is being conducted on a pan-Scotland basis, including regions like the Highlands and Islands. Interested parties should note that the tendering process involves a negotiated procedure with a prior call for competition, and electronic submissions are accepted until 10th November 2025. Businesses across the UK are encouraged to participate, provided they meet the criteria outlined in the procurement documents.

This tender represents a significant opportunity for businesses specialising in manufacturing, installation, and support services for odour control systems, with additional prospects for those providing ongoing maintenance and related services. Given the technical scope and the requirement to conform to various standards and certifications, companies that have experience in similar projects, especially within the water treatment industry, may find themselves particularly well-suited to compete. The framework agreement allows for the delivery of a comprehensive suite of services and equipment, enabling businesses to integrate their expertise in chemical, catalytic, and bio-filtration systems, among others.
