UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

Severn Trent Water Limited is planning a services framework for cleansing, refurbishment and associated maintenance across its Bioresources assets. The work will cover digesters, gas holders, tanks and related infrastructure, supporting their safe, reliable and efficient operation. Planned activities include digester cleansing, tank emptying, refurbishment of digesters and gas holders, and maintenance of associated assets and equipment. Suppliers may need to provide specialist equipment, skilled personnel, project management and technical expertise for both planned and reactive work across multiple sites. The services will be delivered across Severn Trent’s region in England. The procurement is relevant to contractors specialising in sewage-digester operations, industrial tank and reservoir cleaning, purification-plant repair and maintenance, and related water or wastewater infrastructure services.

This procurement is at the planning and market-engagement stage; Severn Trent has stated an intention to procure and has not invited tenders. The buyer expects to establish a framework with two lots: Lot 1 for digester cleansing and other tank-emptying activities, and Lot 2 for digester and gas-holder refurbishment and related assets and equipment. The framework is expected to run from 1 April 2027 to 1 April 2030. Market engagement is intended to gather views on supplier capability, capacity and commercial models, with responses requested by 1 October 2026. The procurement is an above-threshold utilities process. Its estimated value and proposed procurement procedure have not been set out at this stage.

The planned framework should suit specialist water, wastewater and industrial-services contractors able to work safely on large sewage digesters, gas holders, tanks and associated plant. Strong candidates are likely to combine confined-space or tank-cleaning capability with mechanical refurbishment, repair and maintenance expertise. Suppliers should consider whether they have the specialist equipment, suitably skilled personnel, technical knowledge and project-management capacity to support work across multiple operational sites. Experience of planned maintenance and reactive response will be relevant, as the scope is intended to cover both. The buyer is testing the market’s capability, capacity and preferred commercial models, so established contractors and capable specialists forming delivery partnerships may wish to prepare evidence of comparable infrastructure work, operational resilience and regional delivery capacity before the framework reaches the market.
