The Services will commence on 1st April 2027 for a duration of 3 years, with an option to extend for a further 12 months. Corby Closed Landfill Site is located on the northern outskirts of the town of Corby, in North Northamptonshire, grid reference SP877 912. It covers approximately seventeen hectares of which thirteen hectares is landfill. A small part of the site is owned by the Council, but the remainder is leased under a long-term agreement with a local landowner. The Landfill is formed by three (3) cells and a leachate treatment plant. There is a mature tree plantation next to the landfill which also forms part of the site. The volume of wastes within the landfill is estimated to be in the region of 1.4 million cubic metres, with a maximum depth of approximately eighteen metres. The landfill was created in a void (the Gullet) left from the extensive opencast mining of ironstone. Waste was disposed at the site from the early 1970's until the early 1990's when the site was subsequently restored with clay and soil. The waste inputs were largely municipal solid wastes but with some industrial waste. The landfill has no form of impermeable containment and as such is defined as a 'dilute and disperse' site. The site has been capped, soiled, and seeded and there is infrastructure in place to extract and treat gas and leachate. The site has an inert Waste Management Licence (WML) with the Environment Agency (EA) for the importation of capping materials to the site. In 2000, the WML was modified to the Licence that is still in place today. There are several ambiguities to this Licence over which the Council has negotiated local agreements with the EA so that it more accurately reflects the site's characteristics. A Gas Management Plan and a Leachate Management Plan have been approved by the EA which provide the Council with a framework in which to operate the Site and ensures the Site remains in compliance with the Permit. A gas abstraction system and flare stack were installed in the 1990s, after the landfill was closed, and various upgrades have been made together with the installation of several additional combined landfill gas and leachate extraction wells since then. A leachate extraction system was also installed in the mid-1990s which includes a treatment plant, with three aerated treatment lagoons. The treated leachate is discharged to a nearby sewerage network under a Trade Effluent Consent with Anglian Water. The main requirement of this contract is to undertake operation and maintenance tasks to the extraction systems, plant and equipment via detailed schedules of work to ensure the Council complies with the Environmental Permit, Trade Effluent Consent and Lease... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/operation-maintenance-of-landfill-gas-and-leachate-management-systems-at-corby-closed-land-ocds-h6vhtk-06c67d) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planning - **CPV codes:** 90531000 - **Delivery regions:** UKF - **Delivery countries in notice:** GB - **Contract Period:** 31/03/2027 to 31/03/2030 - **Renewal published:** yes ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F064255-2026) - **Last Source Update:** 2026-07-08T13:09:04.000Z - **This document generated:** 2026-10-22T22:14:13.230Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-06c67d
