HWRC Waste Streams & Contingency Requirements

This Lot is seeking the provision of a suitably permitted or licensed waste facility to receive Dewatered Gully Waste. Upon receipt of the waste the Service Provider must ensure that it is stored, transported, treated and disposed of properly and in accordance with all applicable laws, permissions, consents, licenses, permits and the waste duty of care requirements. Treatment options offered should be as far up the waste hierarchy as possible. DGC’s Dewatered Gully Waste – i.e., the solids left after the water is drained off of the waste material that has been sucked out of roadside drains by a street sweeping vehicle – are anticipated to include a mixture of sand, grit, metal and organics. It is estimated there will be approximately 60-75% sand & aggregate and 25-40% organic material (e.g., leaves, twigs & litter etc.). The materials will be likely to include: 0-15mm gully arisings and 16-40mm gully arisings. This material is likely to require treatment to remove inert fractions, or fractions capable of treatment to allow diversion from landfill. DGC dewatering our Gully Waste is a new process, so the anticipated make-up of this waste material is estimated based on feedback from industry and other local authorities. This Lot will be collected by the winning bidder in their own (or a suitably qualified sub-contractor’s) vehicle from the Dumfries MBT plant. Provision of a skip container by the winning bidder is required for this lot. However, as this is a new waste material for DGC, we are open to suggestions for the best way to transport this waste to the winning bidders Nominated Facility. (EWC 19 08 05)
