Summary
Machine-generated summaryWDODelta is preparing a new procurement strategy for the treatment stage of the water chain, covering the period 2027 to 2035. The programme combines maintenance, or upkeep, projects with larger renewal and expansion projects, which differ in nature, scale, complexity and risk profile but draw simultaneously on the same market capacity, specialist knowledge, internal resources and available budgets. To organise the workload in a manageable and efficient way, WDODelta is seeking a balance between serial and integrated delivery. The market consultation invites companies to share practical experience through an information session, a short written questionnaire and targeted in-depth discussions, helping to shape an executable, attractive and future-proof market approach.

As the official award notices state them, over the last 3 years. Tenders per lot count open and restricted procedures only: in a negotiated procedure or a direct award a single tender is the procedure itself. The country is the one the notice gives for the winner.
One dot per award, on the day it was signed, sized by its value. A ring is an award with no published value.
