Summary of the contracting process

The Defence Equipment and Support (DE&S), operating under the Ministry of Defence in the United Kingdom, has announced a planned procurement for the production and maintenance of fresh and technical water systems. The procurement is titled "Fresh Water and Technical Water Production" and falls under the industry categories of non-drinking and drinking water, as well as machinery for purifying water. The headquarters for this procurement is located at MOD Abbey Wood in Bristol. Currently, in the planning stage, the invitation to tender notice is expected around 15 December 2025, with a submission deadline on 14 January 2026. The anticipated commencement date for the contract is approximately 1 September 2026, with an initial contract period of 3 years plus optional extensions, potentially reaching up to 9 years in total.

This procurement presents a significant opportunity for businesses involved in the supply and maintenance of water purification systems, particularly within the defence and maritime sectors. Suitable participants should be capable of supplying spare parts, repair, and maintenance services, alongside supply chain management. SMEs are encouraged to engage, as the procurement is considered suitable for smaller enterprises. The selected procurement method is a competitive flexible procedure, highlighting the need for innovative solutions that can meet the Defence's operational demands. Companies specializing in reverse osmosis and distillation processes would find this opportunity particularly relevant, offering potential for business growth through long-term partnerships and service provisions for the Royal Navy's operational needs.
