Maintenance Services for Leachate Collection & Treatment Systems

Tender description

Lancashire County Council (The Authority) invited for the provision of maintenance services for the Authority's leachate collection and treatment systems. The Authority operates eight waste landfill sites throughout the county of Lancashire. The leachate collection and treatment systems at each site are designed to collect and/or collect and treat leachate prior to its discharge to foul sewer. Leachate is the liquid that drains or "leaches" from a landfill and is an unavoidable product of landfill. The liquid will have passed through materials and extracted solutes, suspended solids or any other component of the material through which it has passed. The Authority has a responsibility to ensure the leachate is collected and treated prior to its safe disposal into foul sewer to avoid pollution. The performance of the Council's landfill drainage treatment systems is regulated by United Utilities Plc and the Environment Agency. The Authority has a responsibility to manage closed landfill sites as well as enforcing environmental standards, as per various legislative requirements such as Environmental Protection Act 1990, Environmental Permitting Regulations 2016 and Water Industry Act 1991. Therefore it is important that the systems designed to achieve these responsibilities are effectively cleaned and maintained. The Services involve pipe work and sewer jetting, leachate sump and tank cleaning, lagoon cleaning and additional services as requested by the Authority from time to time. Additional services includes scope for out-of-hours work although in practice this is a rarity. Lot 1: The Authority operates eight waste landfill sites throughout the county of Lancashire.
