Wetlands can be used as effective rainwater retention and treatment facilities in urban settings. They can be incorporated as part of the city’s sewerage system to improve water resource management and reduce the risk of flooding.
The key principles to consider when selecting and determining the implementation areas for wetlands include analyzing local conditions, using local plant species, and constructing facilities in suitable locations while taking into account factors such as groundwater presence and soil geological structure.
The main advantages of using wetlands in urban environments include reducing pollution of water sources, improving water quality, providing suitable conditions for local flora and fauna, and enhancing the aesthetics of the urban environment.
There are numerous examples of wetland construction in various parts of the world, some of which include:
- Central Park in New York – This urban park includes several wetland areas that have been created as part of the city’s stormwater management system.
Here is a link to the Central Park website where you can find more information about the park and its wetland areas:

The park includes several wetland areas that have been developed as part of the city’s stormwater management system, such as the Loch, Azalea Pond, and Pool G. You can learn more about these areas on the Central Park website.
- Wetland construction in Toronto, Canada – Wetlands in Toronto have been constructed as part of a stormwater management program aimed at improving the water quality in the city’s lakes and rivers.
Here is a link to the Toronto Water website where you can find information about wetland construction in the city:

Here you will find detailed information about Toronto’s stormwater management program, including the measures taken for wetland construction in the city. These areas are created as part of the city’s strategy to improve water quality in Toronto’s lakes and rivers by reducing the amount of pollutants entering these water basins.
- Brisbane, Australia – The “Living Waterways” project in Brisbane consists of a series of wetlands and channels that treat rainwater and utilize it for irrigation in gardens and parks.
These are just a few examples of wetland projects that have been implemented in different cities around the world. These projects demonstrate that wetlands can be created in various urban conditions by considering local circumstances and utilizing appropriate technologies and materials.
The growing interest in wetlands as environmentally sustainable solutions for urban environments indicates that we can expect to see these facilities more frequently in our cities in the future.
