UK7 - Contract Details Notice
Summary of the contracting process

Durham County Council commissioned replacement of the leachate storage tank at Todhills landfill site. Leachate is pumped from collection wells into the tank and periodically removed by a contractor for off-site treatment and disposal. The work covers designing, commissioning and constructing a like-for-like replacement tank, including all associated civil engineering works. It also includes installing a collection sump and pump to capture leachate seeping from the bankside beside the existing tank, and decommissioning and removing the old steel tank. Continuous pumping and off-site tankering must be maintained while the replacement is carried out. The requirement is environmental services and infrastructure work at Todhills landfill site in County Durham.

The procurement is complete and the contract is active. Durham County Council made a direct award without competition under a below-threshold route to SIRIUS ENVIRONMENTAL LTD. The contract was signed on 1 August 2026 and runs from 1 August 2026 to 29 February 2028. Its value is £38,250 excluding VAT (£45,900 including VAT). There was one lot, covering the landfill leachate tank replacement. The award was for environmental services; no award date or evaluation criteria are recorded in the available process details.

For suppliers tracking repeat work for Durham County Council, this award demonstrates demand for specialist landfill environmental engineering: tank design and construction, civil works, leachate collection and pumping, and safe removal of ageing storage infrastructure. Credible competitors would need to manage the transition without interrupting leachate pumping or off-site removal for treatment and disposal. The selected supplier was SIRIUS ENVIRONMENTAL LTD, a small or medium-sized business, showing that this scale of requirement can be delivered by an SME. The council used a direct award without competition, so relevant suppliers should be positioned to demonstrate focused landfill leachate expertise and the ability to deliver an integrated replacement project.
