Wastewater Gardens Initial Research and Project History


The Wastewater Garden will use constructed wetlands technology to purify human wastes and recycle black and gray-water to irrigate trees, shrubs, and flowers. Such gardens, which do not rely on pumps, electricity or chemicals, are well suited to small communities and remote areas as they prevent sewage pollution, which is a leading cause of disease and deterioration of water resources. The project and Nature Iraq’s work in adapting the unique traditions of architecture of the Marsh Arabs will help instill an appreciation of the natural beauty of these historic wetlands.

The realization of waste water garden green technology has outstanding advantages.

•A new green belt between desert areas and the towns will be created
•A green zone in the urban quarters of the towns will be created
•New gardens inside or nearby the towns will be created
•No engine or pumping systems have to work during the day, limiting the impact on the people
