The Danube River is the longest river in Europe, and it will soon receive a new environmentally sensitive sewage treatment plant set on cleaning up its waters. Known as “The Living Danube”, the plant is set to be the most advanced wastewater treatment plant project in Budapest, Hungary, and it will also boast a beautiful green roof.

The 10,000 square meter green roof has been designed as a flat, green surface that will absorb airborne dust and similar impurities. The roof will also drown out noise whilst retaining up to 90% of water – preventing rainwater from draining into the sewer. The rooftop vegetation will also absorb carbon dioxide from the atmosphere and release oxygen, and as an added benefit, it will protect the structure from temperature fluctuations and ultraviolet (UV) radiation, extending its useful life-span considerably.

The primary material in construction will be more than 78,000 square meters of DuPont Typar SF Geosynthetic, a product made of spunbonded, non-woven fabric consisting of 100% polypropylene filaments.  Its high tensile properties and excellent water permeability make it a widely used building material that is also used in road building, drainage systems and inversion roofing.

Bellavics László, a founder of the Hungarian Green Roof Builder Association who designed the “Living Danube” green roof, said, “We have been working with DuPont Typar for over 10 years. Our long-term experience shows the main benefit of DuPont Typar is its unique, thermally-bonded structure which brings an exceptional mechanical strength and durability of the geo-synthetic and longer life to the green roof where it is installed. Another advantage is that its pores do not clog with soil particles, which guarantees its long-term filtration ability.”

    Waters that are used for drinking, manufacturing, farming, and other purposes by residences (toilets, baths, showers, kitchens, sinks), institutions, hospitals, commercial and industrial establishments are degraded in quality as a result of the introduction of contaminating constituents. Organic wastes, suspended solids, bacteria, nitrates, and phosphates are pollutants that commonly must be removed.

    To make wastewater acceptable for reuse or for returning to the environment, the concentration of contaminants must be reduced to a non-harmful level, usually a standard prescribed by the Environmental Protection Agency.

    Sewage can be treated close to where it is created (in septic tanks, bio-filters or aerobic treatment systems), or collected and transported via a network of pipes and pump stations to a municipal treatment plant.
