WODA Policy Documents

Common values and principles across the globe

World Organisation of Dredging Associations (WODA) is composed of three independently operating sister associations:

  • Western Dredging Association (WEDA) serving the Americas,
  • Central Dredging Association (CEDA) serving Europe, Africa, and the Middle East, and
  • Eastern Dredging Association (EADA) serving the Asian and Pacific region.

WODA Policies

The WODA Environmental Policy was adopted in 1998 during the 15th World Dredging Congress, USA. Since then, at subsequent World Dredging Congresses, two further policy documents have been adopted. These documents build on the preceding statements.

Operating globally, the three WODA constituents, WEDA, CEDA and EADA, sometimes find significant differences in the way dredging projects are planned and implemented. The three WODA policy statements capture the common values and principles to which each association subscribes.

Principles of Sustainable Dredging (2013)

...emphasises the need to work in harmony with natural processes and the site-specific characteristics of ecosystems. Projects should take into account social, environmental and economic objectives and should engage a broad range of stakeholders from the start. The Principles also state that beneficial use of dredged materials should be a priority. By following this blueprint, WODA believes that dredging will contribute to sound solutions that improve our well-being and protect our aquatic environment for future generations.

Hamburg Declaration (2004) -  From Gaps to Integration

In this document, the constituent bodies of WODA declare their commitment to assist with knowledge and expertise in bridging the many gaps that exist in relation to the development and implementation of dredging activities.  

WODA Environmental Policy (1998)

...embraces environmental protection as a critical factor in successful dredging projects. It clearly states that cost-effective and timely dredging projects can be accomplished in an environmentally sound manner. The WODA Environmental Policy applies to all aspects of WODA interests including construction, maintenance, mining and remedial dredging (clean-up of contaminated sediments).
