Water tenders — page 17
810 listings tracked right now · page 17 of 17
Grants and contracts for water supply, treatment, reuse and resilience. The active funders are the World Bank and regional development banks, EU LIFE and Horizon, the US EPA, and water utilities procuring through the public-tender feeds. Listed below are the open water tenders and contract notices that landscape produces, taken from each buyer's own notice and re-checked on every refresh.
Procurement is dominated by water utilities, port authorities, municipalities and the development banks financing them. Contracts are typically works or long-term services rather than research, and prequalification on prior comparable projects is common. Development-bank-financed notices follow the bank's own procurement rules, which are generally more open to non-domestic bidders than a purely national tender would be.
This page lists open water tenders and public contracts currently tracked by Raise Lens — 810 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is water work rather than anything whose description happens to mention it.
38 distinct buyers are publishing the water tenders and public contracts on this page. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between buyers than between individual calls, which is why the listing names the buyer on every opportunity it opens.
