Before you bid on this tender
A quick checklist to help you decide whether to bid and prepare a compliant submission for this water & environment opportunity. Always verify the details on the official source.

- Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
