This initiative falls under the electrical equipment and apparatus industry category and is located in various regions across the United Kingdom, including North East, North West, Yorkshire and the Humber, East Midlands, West Midlands, Scotland, and Wales. Currently in the planning stage, interested parties have until 18 September 2018 to engage and express interest in this tender, with an early engagement notice published on 28 August 2018. This tender represents a significant opportunity for businesses involved in electrical engineering, environmental services, and water treatment. Companies specialising in pilot testing, laboratory services, and plant conceptual design would be particularly suited to compete, as they can contribute to the Coal Authority's objectives in managing mine water contamination and exploring hazardous waste strategies. This engagement could also enhance business visibility and lead to collaborative projects within the water treatment sector. ## 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 mine water can be net acidic or net alkaline and contain a variety of dissolved anions and metals cations. The salinity of mine water can also vary dependent on the site. The Coal Authority is now considering the potential of electrochemical treatment plants in treating mine water. Selective precipitation of metals dissolved in mine water would provide the Coal Authority with options for a hazardous waste management strategy and disposal, as well as the potential to recover metals of commercial interest. The fate of sulphates, carbonates and chlorides in the electrochemical process would also need to be considered. Areas of interest of the Coal Authority include: * Sample collection and preparation * Laboratory testing (off and on site) * Pilot testing (off and on site) * Analytical Capabilities * Plant conceptual design * Whole life costs * Electrocoagulation * Methodology of removing solids deposited on electrodes (mechanical or physical or chemical) 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 or wish to express interest please contact 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/ccfe86a7-4e1f-4ae5-ae8b-2b61baf99568 | | 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 - 31 - Electrical machinery, apparatus, equipment and consumables; lighting - 33 - Medical equipments, pharmaceuticals and personal care products - 65 - Public utilities - 71 - Architectural, construction, engineering and inspection services - 73 - Research and development services and related consultancy services ### Codes - 31600000 - Electrical equipment and apparatus - 33158000 - Electrical, electromagnetic and mechanical treatment - 65121000 - Water demineralisation services - 71334000 - Mechanical and electrical engineering services - 73100000 - Research and experimental development services ## Release History - 28 Aug 2018 at 11:03 - Planning - Market Engagement Notice - https://www.contractsfinder.service.gov.uk/Notice/ccfe86a7-4e1f-4ae5-ae8b-2b61baf99568 ## Documents - https://www.contractsfinder.service.gov.uk/Notice/ccfe86a7-4e1f-4ae5-ae8b-2b61baf99568 28th August 2018 - Early engagement notice on Contracts Finder - https://www.contractsfinder.service.gov.uk/Notice/Attachment/e0c985a6-a7ae-47b1-8a35-e89e2b1c0192 PIN Notice ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
