This initiative focuses on plant engineering design services relevant to the treatment of mine water and includes the addition of pH correcting or oxidising reagents. Interested parties are encouraged to engage with the Coal Authority by expressing their interest no later than 18 September 2018. The procurement is based in Mansfield, England, with potential implications for various regions across the UK, including the North East, North West, and Yorkshire and the Humber. This tender presents significant opportunities for businesses specialising in plant engineering design, environmental services, and sludge treatment. With the Coal Authority seeking feedback and suggestions on their requirements, businesses that can provide innovative design and testing solutions, particularly those capable of scaling from laboratory to pilot testing, would be well-suited to compete. The engagement process may involve both individual and group meetings, allowing for collaborative discussions that could lead to future contract opportunities. ## Notice The Coal Authority operate over 75 minewater treatment schemes that remove contaminating metals from mine water prior to the treated water being discharge into a receiving watercourse. Schemes range from complex process engineering plants, through pumped wet wells and boreholes/mineshafts, to totally natural (passive) schemes without a power source. A number of sites require the addition of pH correcting or oxidising reagents. Flow rates range from circa 5 litres/sec to 400 litres/sec. A standard pumped treatment scheme utilizes 32 digital inputs, 8 analogue inputs and 8 digital outputs. The majority of treatment schemes comprise of aeration cascades, settlement ponds and reed beds. All schemes are subject to regulatory consents and licenses. The Coal Authority is now considering the potential of High density Sludge (HDS) plants in treating mine water (acidic and alkaline) as well as the potential benefits that can be achieved with a sludge management system. From a Coal Authority perspective, the sludge generated (principally ochre) would be predominantly iron oxy-hydroxides with other metal hydroxides. The characteristics of the resultant ochre from a HDS plant are a consideration for the Coal Authority, as potential markets for ochre may arise in the future. Areas of interest of the Coal Authority include: * Sample collection and preparation * Laboratory testing * Pilot testing (off and on site) * Analytical Capabilities * Plant conceptual design * Whole life costs We would like to invite interested companies to meet with us at our Mansfield office during September / October 2018 to better understand our requirements and offer suggestions on how we might fulfil our objectives through a future tender process. Once the Coal Authority has assessed interest, it will advise on if meetings are to be conducted on an individual basis or as a group with multiple companies present. If you have any queries please express your interest by contacting peterkobryn@coal.gov.uk no later than 18 September 2018 Participants should note that we reserve the right to use any information shared within this market engagement to develop a mature service specification for future procurement purposes. Any costs incurred by participating in this exercise must be borne by the participating organisations. Following this exercise we shall determine if and how we will approach the market to secure the services. Please note that any future procurement will be subject to a separate advertisement ## Key Details | Field | Value | | --- | --- | | Publication source | Contracts Finder | | Latest notice | https://www.contractsfinder.service.gov.uk/Notice/efcfba40-3d6b-4a61-8b35-3e0428548290 | | Notice type | Market Engagement Notice | | Procurement type | Standard | | Procurement category | Not specified | | Procurement method | Not Specified | | Procurement method details | Not specified | | Tender suitability | SME | | Awardee scale | Not specified | | All stages | Planning | ## Dates | Field | Value | | --- | --- | | Publication date | 28 Aug 2018 | | Submission deadline | Not specified | | Future notice date | 18 Sep 2018 | | Award date | Not specified | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Planning | | Lots status | Not specified | | Awards status | Not specified | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | THE COAL AUTHORITY | | Locality | MANSFIELD | | Post town | Nottingham | | Postcode | NG18 4RG | | Country | England | | ITL 1 | TLF East Midlands (England) | | ITL 2 | TLF1 Derbyshire and Nottinghamshire | | ITL 3 | TLF15 North Nottinghamshire | | Local authority | Mansfield | | Electoral ward | Berry Hill | | Westminster constituency | Mansfield | | Delivery location | TLC North East (England), TLD North West (England), TLE Yorkshire and The Humber, TLF East Midlands (England), TLG West Midlands (England), TLL Wales, TLM Scotland | ## CPV Codes ### Divisions - 71 - Architectural, construction, engineering and inspection services - 79 - Business services: law, marketing, consulting, recruitment, printing and security - 90 - Sewage, refuse, cleaning and environmental services ### Codes - 71323200 - Plant engineering design services - 79930000 - Specialty design services - 90513800 - Sludge treatment services ## Release History - 28 Aug 2018 at 10:04 - Planning - Market Engagement Notice - https://www.contractsfinder.service.gov.uk/Notice/efcfba40-3d6b-4a61-8b35-3e0428548290 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/efcfba40-3d6b-4a61-8b35-3e0428548290 28th August 2018 - Early engagement notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/b6fc200e-b70e-4875-bad3-f6aac3b30cf8 ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
