description
The Defence Infrastructure Organisation (DIO) on behalf of the Ministry of Defence (MOD), is looking to secure the provision of end-to-end WWW services for the MOD’s specified estate in England and Wales, through a single Managed Service Provider (MSP).
MOD has a significant and geographically dispersed WWW estate in England and Wales with a combination of public supply and its own private water network. The Contract will go-live in 2 main stages with Wales and South-West England going first on 01 Dec 2028, with the rest of England on 30 Mar 2030, with the other smaller requirements going live as the Authority’s other contracts and agreements expire or earlier with the agreement of the MSP.
The Defence Water Services Programme (DWSP) will deliver a single contract to effectively support, manage and assure supply chain WWW service provision, delivering a common user experience across the England and Wales estate. Due to the extent and dispersed nature of MOD WWW assets, the MSP will need to demonstrate all technical competencies required to deliver the full spectrum of WWW services which may include but may not be limited to:
