....................... Practical Information .......................

As of January 2013, we have made several documents available in our "Overview download" section that extend to pratical and complementary fields of knowledge to constructed wetlands that you may find useful. We recommend in particular the document called "WWG_InfoSheet_AboutSewageAndTreatment.pdf" as it will provide you with a good overview and understanding of the nature of wastewater, sewage in particular, as well as its treatment principal framework.You will also find a worldwide water consumption data sheet.

2023 March - EDEN IN IRAK, Irak
No more sewage in the Marshland!
Completion of the 1st stage of a surface and subsurface-flow constructed wetand treatment system (2000 m3/day).

2022 - 2014 - Project Irak
In March 2014 the Iraqi government approved and agreed to fund constructed wetlands of WWG design to treat two Marsh Arab towns with populations from 15-45,000 people (Al Manar and Al Fuhud). This was the third visit of the WWG team, starting in 2011. In March 2013, a workshop in constructed wetlands technology was conducted for engineers and scientists from the Iraqi Ministries of Water Resources, Environment and the Protection of Iraqi Wetlands.
The project was initiated by Nature Iraq (NI) (http://www.natureiraq.org/waterkeepers-iraq.html), a local organization set-up to preserve important ecological regions and distinctive cultures in Iraq and creator of the Mesopotamian National Park, the first National Park in Iraq, to protect these marshes and the Marsh Arab culture, among the oldest in the world. These marshes were turned into desert in the 1990s when in punishment for an uprising against the government, diversion canals 800 km long, sent the Tigris and Euphrates Rivers to the west. Since 2003, the diversion canals have been ruptured by local Marsh Arabs, and now over half the original marshlands, an important migratory bird habitat, has been restored. Up to half a million Marsh Arabs who were forced to leave are now returning to the region.
The first constructed wetland will also feature symbolic, historical and artistic elements in a project entitled, Restoring Eden, spearheaded by Prof. Meridel Rubenstein of the Nanying Technical University of Singapore working in collaboration with our team (www.meridelrubenstein.com/eden-in-iraq; https://edeniniraq.com).

2005 – Australia

The Royal Australian Institute of Architects, 2005.
The beneficiary was “Coco Eco Nature Retreat” (http://www.cocoeco.com.au/) which has used Wastewater Gardens for its sewage water treatment and ecoscape. The building was completed in May 2004 and won the prestigious 2005 WA Architectural Award for single residential.
Jury comments: " ... The resulting complex not only works from a sustainability point of view, but creates the ambience requested by the client in an unforced and natural way by adopting forms and materials that reflect the tropics ...The resulting project could well serve as an exemplar for similar projects in the future… Environmental sustainability has been embraced and celebrated within the development with the waste water garden at the entry and centre of the buildings serving as living reminder of a commitment to a more sustainable building and operational practice ... ».
