Liquid Waste Removal and Drainage Services
Authority: Northern Trains Ltd (Public body)
What is being bought
Published requirement descriptionNorthern Trains Limited ("NTL") has completed a procurement process for the provision of Liquid Waste Removal and Drainage Services across its network.
The procurement has established a single supplier Framework Agreement to support NTL's requirements for liquid waste management and drainage services across its train maintenance facilities.
NTL undertakes train maintenance activities across a number of locations. At the time of award, services are required across 11 maintenance sites, although the number of locations covered by the Framework Agreement may increase or decrease during the term of the agreement.
The awarded supplier will provide services including, but not limited to:
- Removal of liquid waste from waste tanks containing fluids drained from trains, including coolant and oil;
- Emptying and management of oil/water separators, including sludge, water and oil;
- Septic tank emptying and waste management;
- Drainage maintenance and associated services.
The scope of the Framework Agreement also includes:
- Drain jetting, drain clearance and CCTV surveys in accordance with NTL's lease obligations;
- Maintaining drainage systems within TrainCare Centre ("TCC") maintenance areas to ensure they remain free from sediment, including sand, and support ongoing engineering operations;
- Supporting NTL's environmental objectives, including the reduction of waste sent to landfill.
The awarded supplier is responsible for assessing, classifying and managing waste in accordance with applicable waste and hazardous waste regulations, including:
- Assignment of the appropriate European Waste Catalogue (EWC) code and waste description;
- Identification and documentation of transportation hazards and associated control measures;
- Provision of all information required to complete waste consignment notes and waste transfer documentation.
For each waste collection, the supplier shall arrange laboratory analysis of samples through a UKAS-accredited laboratory. The results of the analysis shall be used to support the preparation of the relevant waste consignment documentation and must be provided to the relevant NTL site representative together with the completed consignment note prior to removal of the waste.
- How the procedure runs: The Tender stages will be run as follows: Stage 1 All interested suppliers may apply to participate in this procurement via https://www.delta‑esourcing.com using Tenderbox Reference: BDGN4R5X52. Optional site visits may be undertaken where applicable. Following submission, Tender Responses will initially be checked for compliance, including that all required returnables for the response have been submitted. If NTL does not consider a Tender Response compliant, it reserves the right not to carry out any further evaluation and eliminate the supplier from the procurement. Compliant Tender Responses will be evaluated in line with the published criteria: Technical Quality (40%), Pricing (50%), and Social Value (10%). NTL will undertake a comprehensive evaluation process to determine the Most Advantageous Tender (MAT). NTL may, at any stage, request clarification on any aspect of a supplier's Tender Response, though it is not obliged to do so. Notwithstanding the foregoing, at any stage following the submission of a Tender Response, NTL may require Negotiation Meetings in which the supplier may be required to present their Tender Response for the purposes of verifying any aspect of that Tender Response. The supplier will be required to make suitable personnel available to NTL in order to resolve NTL's queries. Any clarification discussed at such meetings will be agreed by NTL and the supplier, documented, and submitted by the supplier through the message centre on Delta. Stage 2 (Optional) - Following evaluation of the ITN, NTL may invite the 3 highest‑scoring Tenderers to submit Best and Final Offers (BAFOs). - BAFOs must follow instructions issued via Delta and be based on final Specification, Contract, and Pricing documents. - No amendments to the final‑form contract documents are permitted. - BAFOs will be evaluated using the same criteria and methodology as the original Tender Responses. - Whilst NTL may request BAFOs, suppliers should not rely on any potential subsequent opportunities for providing improved commercial offers.

- Price carries 50 of 100 points: a 10% discount moves about 5 points. This one is won on the number: sharpen the price before polishing the prose.
- “Liquid Waste Removal and Drainage Services” is a framework: the contest is a place on its panel, up to 1 suppliers, not a single contract, and call-offs are awarded directly: getting appointed is the whole game.
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.

|---|---|---|---|
| Adler and Allan LtdLiquid Waste Management and Drainage Services - Framework31 Aug 2026 – 30 Aug 2030 · up to 30 Aug 2034Extensions: The Contract will be let for an initial term of four (4) years. Following the expiry of the initial term, NTL may, at its sole discretion, exercise up to two (2) extension options of two (2) years each (a potential maximum contract duration of eight (8) years). Extensions may be considered where: Service performance has consistently met or exceeded the required KPIs, including compliance, responsiveness, environmental standards, and reporting obligations. Operational continuity is desirable to avoid service disruption, particularly where ongoing site‑specific knowledge or specialist waste-handling expertise is beneficial. Value for money can be demonstrated, including benchmarking or a review showing that the extension period remains commercially advantageous. Regulatory compliance continues to be maintained, with the supplier remaining appropriately licensed for handling, transporting, and disposing of liquid waste. Business needs remain unchanged, and the scope and volume of liquid waste removal services are still required in line with the existing specification. If both extension options are applied, the breakdown is as follows: Initial Term: 4 years Extension Option 1: 2 years Extension Option 2: 2 years Maximum Contract Duration: 8 years total · Options: NTL may request additional deliverables or services that are not explicitly listed in the scope of this procurement. Where such requirements arise, pricing will be agreed within the relevant work order, subject to the following conditions: - Any pricing related to design, build, or management services must remain consistent with the rates set out in the framework. - All agreed prices must be clearly linked to comparable items already included in the framework pricing schedule. - The appointed supplier will be required to provide supporting evidence to justify the proposed pricing. | £3,912,630 | 11 Aug 2026standstill to 20 Aug 2026 | Standstill |
