Since 1847 Carlsberg Byen, an area in Copenhagen, has been home of the brewery Carlsberg, but now it will be transformed into a new living quarter in Copenhagen. Frederiksberg district cooling (Frederiksberg Fjernkøling) has initiated the work of establishing a 11MW district cooling plant in the new Carlsberg quarter. This is the start of a larger […]
AVK recently supplied a large number of valves to the Ashton Avenue site, one of Wessex Water’s largest sewage pumping stations in the South Bristol region in England. The Wessex Water waste water collection and pumping station was originally built in the 1960 and was scheduled for refurbishment and upgrade to help reduce the risk […]
At 7 pm on Thursday 7 June 2012 AVK Syddal was contacted by the Sales Manager at AVK Danmark. The Sales Manager in Denmark had just received an emergency call from Copenhagen Energy, the utility responsible for the gas infrastructure in Denmark’s capital city. A large DN 1100 cast iron gas main had ruptured catastrophically […]
It is of great importance to reduce water losses in Malaysia. The government focuses on repairing old pipelines and building new ones, not only for environmentally reasons but also for economically reasons. The price of water in Malaysia is very low and do not cover the actual costs. The huge amount of unidentified water loss […]
At the wastewater treatment plants, the grease and sand is removed by means of a grease and sand trap to ensure that the equipment in the following processes is not damaged. The wastewater is cleaned in steps where the sludge is separated and often used for biogas production, used either locally by the plant or […]
Before the wastewater is discharged (into a stream, creek, river or the sea) it must be ensured that local legislation is fulfilled with regards to discharge specifications of a number of harmful substances to the environment. In the EU countries, each wastewater treatment plant is obliged to document the content of harmful substances in the […]
Wastewater collection is normally done by means of gravity from domestic households and/or the industry where the wastewater is led to pump stations where it is pumped into the wastewater treatment plants. Rainwater is also collected in sewers and led either directly to the pump stations or to rainwater storage tanks where it at a […]
Typically water transmission pipelines are either constructed using concrete pressure pipes, ductile iron pipes, steel pipes or GRP/GRE pipes. At the lower end of the dimensional range plastic pipes (such as HDPE) may be used. There are various historical/design reasons as to why individual authorities & consulting engineers may prefer different valve designs. Some designers […]
Waterworks collect water from many different locations; i.e. groundwater (aquifers), surface water (lakes and rivers), water reservoirs and even seawater (through desalination). Regardless where the water is collected from, it must be purified before use. Water from certain areas may only require filtration and aeration whereas water from other locations may need disinfection through chlorination […]
When water has been treated in a water treatment plant, it will be pumped to the consumer via a wide distribution network. This network is made of different kinds of pipe material; typically ductile iron, PVC, steel or PE. A distribution network usually functions at a relatively low pressure, but water pressures may vary in […]
In Israel the water resources are limited and several of the farmers around the Negev desert have been forced to let their fields dry out because of the lack of water resources. This has affected the local standard of living and Israel has been forced to think of alternative solutions. One solution has been water-saving […]
In the capital region of Denmark, they listen carefully to their water distribution networks. The country’s two largest water suppliers, HOFOR (Greater Copenhagen Utility) and Novafos, have transformed parts of their water distribution networks around Copenhagen into full-scale demonstration areas with state-of-the-art technology
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.
Good water management can make cities healthier places to live, resilient towards climate change and more sustainable overall. Without proper sanitation, sewerage and clean water supply, there is no liveable city. This white paper features lessons learned from different Danish stakeholders within urban water management. It is meant to serve as a tool for inspiration for creating innovative water solutions, which contribute to smarter and more liveable cities.
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.
