    Brief

    Northern Trains Limited seeks a supplier to provide comprehensive liquid waste removal and drainage services across its train maintenance network. The Framework Agreement covers 11 maintenance sites initially, with potential for expansion or reduction during the contract term. Key services include: removal of liquid waste from train tanks (coolant, oil, etc.), emptying and management of oil/water separators, septic tank emptying, and drainage system maintenance. The supplier will conduct drain jetting, drain clearance, and CCTV surveys to meet lease obligations and maintain drainage systems free from sediment within TrainCare Centre areas. The successful supplier must classify and manage all waste according to applicable regulations, assign appropriate European Waste Catalogue codes, document transportation hazards, and prepare waste consignment notes. For each collection, the supplier must arrange laboratory analysis through a UKAS-accredited laboratory and provide results to site representatives with completed documentation before waste removal. The role supports Northern Trains' environmental objectives by reducing landfill waste.
