How Norway’s Bridges Clean Rainwater Runoff Using Moss Walls and Gravel Trenches

 

The New Environmentally-Friendly Water Protection.

Norway has started to accept moss walls and gravel-filled trenches in bridges to clean the rainfall runoff. This is a new system, which enhances the quality of water and safeguard the iconic fjords of the country.

The problem with Traditional Runoff.

Pollution of roads and bridges are carried to the ground by rainwater. Such pollutants tend to enter the rivers, lakes and fjords without being regulated and damage marine life.

Natural Moss Walls.

The moss walls retard the flow of water and absorb the contaminant. Moss acts as a natural bio-filter as it picks up the oil droplets, dust and heavy metal particles.

Gravel Trenches Addition of Secondary Filtration.

Gravel traps out the sediments and other toxic chemicals rendering the water very clean when it comes out.

Planned to be Environmentally Sustainable.

In contrast to the mechanical filtration systems, moss and gravel do not consume much energy and have very low maintenance. The design is greener and economical.

Conserving Fjords in Urban Pollution.

It is known that the fjords of Norway are the world natural treasure. Their beauty, water clarity, and ecology is preserved with the help of cleaner runoffs.

Protecting Marine Wildlife and Ecosystems.

Filtered discharge makes the waters healthier to fish, crustaceans, seabirds, and aquatic plants. Recovery of water quality enhances the whole food chain in the water.

Using Green Roofs to Help Cities Process Stormwater.

Global warming creates increased precipitation. Norwegian filtration bridges channel rainwater to the natural systems instead of sewer and water flooding with polluted runoffs.

A Novel Interchange of Nature and Engineering.

The filtration layers were made to resemble natural processes by engineers. The bridges are mini-ecosystems that purify water like forests and wetlands.

A Sustainable Urban Infrastructure Model.

Norway can be emulated by other countries that aim at finding low-cost water purification solutions. Moss filtration is cheap and can be used in varying climatic conditions.

Enhancing the aesthetics of the Public Structures.

Green moss walls transform a normal bridge to a beautiful living environment that fosters environmental health as well as beautifying cities.

Value and Public Education.

The bridges are used in schools and universities to educate the students on natural filtration, climate resiliency and ecological engineering.

In the Long-term, the Water Quality will be improved.

In the long term, filtered runoff will result in cleaner fjords, healthier coastlines and a better biodiversity. This establishes long term gains to locals and industries.

Distributing the System to Additional Cities.

Norway will also expand the use of moss-based filtration to more bridges, tunnels and urban drainage systems in the country.

A Global City Scaleable Solution.

Big cities with contaminated waterways have an opportunity to use the moss-and-gravel technique and enhance water quality at the lowest cost.

Stronger Climate Change Resilience to Future Generations.

Cleaner water systems enable people to withstand the environmental challenges and safeguard natural resources in decades to come.

On the forefront in terms of Green Infrastructure.

The innovative runoff filtration in Norway is also a manifestation of outstanding sustainability in engineering and conservation of the environment.

A Vision of Urban Landscapes of Greener and Cleaner.

When popularized, natural filtration systems would make cities a greener, healthier and more sustainable place to reside.

Conclusion: Norway Shows That Nature Is the Best Filter.

Norway uses a technique of cleaning rainwater runoff using moss and gravel to demonstrate how simple natural solutions can save fjords and make the environment more robust.
