Waste Management Services

The Coal Authority currently operate 161 individual reed beds providing treatment capacity at 59 mine water treatment sites and 130 settlement ponds at 53 sites. The purpose of the mine water treatment sites is to remove iron that has been mobilised from old mine workings into groundwater. These mine water treatment sites operate by enabling oxidation of the iron, which is then precipitated as iron hydroxide (ochre) and settled in settlement ponds. The effluent from the settlement ponds is then passed through reed beds to polish the water before discharge to local water courses under discharge consents. The reed beds are planted with a variety of wetland plants that act primarily as filters to remove any remaining ochre from the water before it is discharged. Over time there is a build-up of ochre within the settlement ponds and biomass from reed growth together with the ochre and any wind-blown dust that is captured within the reed bed. For the reed beds and settlement ponds to operate correctly the available headroom for the water levels have to be maintained within an acceptable range. So an amount of this build up has to be removed periodically and disposed of through an environmentally sustainable route. To achieve the removal of the build-up within the reed beds and settlement ponds, we require a competent and experienced contractor(s) to provide an environmentally sustainable disposable route for the reed bed and settlement ponds material. The contractor(s) will need to demonstrate their ability to dispose of the material complying with the permits required for disposal and their expertise in finding environmentally friendly disposal routes i.e. not landfill Permit required for reed bed material disposal: • Bespoke mobile plant permit for land spreading using EWC 19 13 06. Following market analysis and feedback from market engagement the requirements will be structured across three lots to maximise the probability of the most beneficial outcome being delivered and to lower barriers for SME's: • Lot 1 - Reed Bed Management Excavation, transplant existing reeds, procure and plant new reeds - £1.75m per annum - £7m per framework • Lot 2 - Reed Bed Disposal: - Transportation and sustainable disposal avoiding landfill - £1.75m per annum - £7m per framework • Lot 3 - Sludge & Ochre Management - Lagoon desludging, excavation, transportation, ochre preparation, packing and haulage - £1m per annum - £4m per framework The estimated values are based on the budget granted to the Coal Authority currently for these services. This is subject to change and not guaranteed.
