As one of the most innovative water companies in Denmark, we feel obliged to support the water industry. We have extensive knowledge of the operation of various facilities, establishment of organisations, analysis, tendering, planning, project management, training and commissioning of facilities. We would like to do our share towards ensuring innovation of the Danish water industry.
By also taking a global perspective, we contribute knowledge and support for Danish exports and help set the global agenda for sustainable development.
The plant, which will replace the existing Marselisborg wastewater treatment plant in 2028, will be a state-of-the-art treatment center and stand as a stunning landmark on the Aarhus harbour front. Upon completion, it is expected to be the world’s most sustainable and innovative wastewater treatment plant.
Up to 10,000 households’ washing machines and toilets in the suburb Nye – near the city of Aarhus – will soon use rainwater instead of drinking water. This is estimated to cut water consumption by as much as 40 percent.
Watch the launch of Aarhus Vand’s innovation strategy for Marselisborg ReWater. The kick-off event was attended by the Mayor of Aarhus, Jacob Bundsgaard and representatives from companies, research institutions and organisations who were all invited to help Aarhus Vand develop the world’s most resource-efficient wastewater treatment plant.
At Aaby and Marselisborg Wastewater Treatment Plants Aarhus Vand extract phosphorus from the wastewater and sell it as valuable fertiliser under the name PhosphorCare. In 2013, Aarhus Vand opened the first full scale demonstration plant in Denmark at Aaby Wastewater Treatment Plant to test the viability of renewable phosphate production in Denmark. Today the plant […]
Total energy renovation of the treatment plant at Egaa, just outside Aarhus, means that Aarhus Vand is setting new standards for developing treatment plants from energy guzzlers into energy producers. This has happened through entirely new technologies that exploit the green energy-production potentials in wastewater. The topping-out is a milestone in the technological development of […]
In recent years we in Aarhus Vand have entered into voluntary agreements with landowners regarding pesticide-free cultivation of the vulnerable areas. Through investments in afforestation we contribute to the plantation of new forests. In selected areas, we successfully run information campaigns together with the local waterworks and joint councils for the purpose of reducing the […]
At Marselisborg Wastewater Treatment Plant we in Aarhus Vand produce 50 percent more energy than we use. By implementing energy efficient solutions and producing biogas from the sludge, we are almost able to cover the energy consumption for the whole water cycle from the groundwater extraction, to pump stations, water distribution and wastewater treatment.
In Aarhus Vand we have focused on optimising water distribution for many years, and we have now managed to reduce our water loss to only five percent. Increasing water consumption will lead to an even greater supply gap for countries already facing water stress. In order to meet the future demand for water, a strong […]
Increasing rainfall means that pipe capacity is too small in many places, with excess water – a hazardous mixture of wastewater and rainwater – flowing into lakes, streams or sea untreated. The excess water also causes flooding of cellars, roads and green areas. In other words, we lack space in our sewer system, and Aarhus […]
In 2014, Leif Koch, DHI, and Ramböll partnered with the Taipei Office of the Trade Council of Denmark and the Taiwan Water Corporation for a pilot project to reduce water loss in Taiwan. These organizations sent a team of leakage engineers and operators to work at a test site on Chijin Island. With the rising […]
With the help of Danfoss drives, the Aarhus wastewater treatment plant in Denmark not only ensures clean water – it also produces more electricity and heating than it consumes. Water and wastewater facilities account for the largest consumption of electricity in most municipalities, typically 25-40% of the total energy use. In the Danish city of […]
As the climate changes and the number and frequency of rainfall events increases, so does the need for intelligent rainwater management solutions. This White Paper presents insight into lessons learned from Danish stakeholders within rainwater management and Sustainable Urban Drainage Systems (SUDS).
25-50% of all distributed water globally is lost or never invoiced due to illegal connections, inaccurate billing systems, inaccurate metering, leakages, deteriorating infrastructure and wrong water pressure management etc. – or in short Non-Revenue Water (NRW). This white paper examines how water utilities can improve efficiency and meet future demand for water by reducing Non-Revenue Water.
On a global scale, less than half of all wastewater is collected and less than one fifth is treated. This has led to severe environmental degradation of many inland and sea waters around the world. This white paper provides lessons learned from Danish stakeholders within wastewater treatment.
