Description
The Defence Infrastructure Organisation (DIO) on behalf of the Ministry of Defence (MoD), is looking to secure the provision of end to end Water and Wastewater services including the Operation and Maintenance (O&M) of the MoD's private water network through a single, national Managed Service Provider (MSP).
More information about the services and MSP is included in the DWSP Concept Document available at: https://contracts.mod.uk/esop/guest/go/opportunity/detail?opportunityId=60136
If you wish to provide feedback or comments on this Concept Document please send them to DIODCT-PFIRP@mod.gov.uk .
This Notice is intended to notify industry of the planned procurement dates and is also a call for an Industry Day at Villa Park, B6 6HE on 14th October 2025. This will provide an opportunity for industry to engage with the DWSP Team, wider DIO representatives and other members of the industry. The MSP Concept Document has been designed to provide insight to MoD`s proposed design of arrangements, to be utilised and implemented by the selected Managed Service Provider. The content as well as Commercial Topics such as Tender Timelines and the Procurement Specific Questionnaire (PSQ) will drive much of the conversation at the Industry Day, and we encourage you to submit questions by means of SLIDO that will be distributed in advance of the event.
The day will encompass the following activities:
1. Overview and update of the requirement by DIO.
2. Dialogue around the commercial considerations that the team is working through.
3. Networking opportunity with other providers (Prime Contractors and Small and Medium Enterprises (SMEs)).
As part of MoD policy DIO encourages and supports SME engagement, and will have limited floor space at the event dedicated to SMEs who are invited to bring small display equipment and literature if they wish. Further detail of SME involvement and information on how to sign up are available through:
https://www.find-tender.service.gov.uk/Notice/050897-2025
