We strive to make this knowledge globally accessible to clients and partners by channelling it through our local teams and unique software. Whether you need to save water, share it fairly, improve its quality, quantify its impact or manage its flow, we can help. Our knowledge, combined with our team’s expertise and the power of our technology, holds the key to unlocking the right solution.
The area of Augustenborg in Malmö, was retrofitted with a green open stormwater system in the late 90s. When a major rainstorm hit the city of Malmö in August 2014, Augustenborg was less affected by flood damage than nearby areas. Since the retrofitting of the stormwater system, it was unknown if the solution was efficient […]
Severočeské Water and Sewerage Company (SCVK a.s.) in Teplice operates the largest regional water supply system and distribution network in nearly 400 settlements in the Czech Republic. However, their water supply system was in a bad shape – suffering from high levels of leakage of up to 40% and an unbalanced flow and pressure distribution.
Implementation of DHIs Non-Revenue Water Solution in close collaboration with infrastructure owner and the operator.
Cape Town’s water system was hard to control, with plenty of data available but hardly accessible. DHI established a Dynamic Integrated Monitoring System (DIMS), providing managers with fast and easy access to all necessary information regarding water quality, supply, sewage collection and treatment and disposal.
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 […]
In 2013, Leif Koch participated in a project in Rajkot, India, in collaboration with DHI and Grundfos. We worked to improve and stabilize the local water supply, as water scarcity was so extreme that Rajkot inhabitants only had running water for a few hours each day. Leif Koch provided leak detection services for the Rajkot […]
For more than four decades, the worldwide demand for fish has increased at almost twice the rate of the growth in global population. This White Paper presents best practice examples of resource efficient sea and land-based aquaculture solutions for farming high quality seafood.
The exploitation of freshwater resources, population growth and the impacts of climate change calls for water management based on sound knowledge and sustainable practices. This White Paper covers the Danish approach to Integrated Water Resource Management and addresses complex water challenges.
Soil is literally the foundation on which we will build a sustainable future. Despite this, soil is contaminated, exploited, and degraded all over the world. Insides this White Paper is an overview of the Danish sector for soil and groundwater remediation and the companies which contribute to its development.
Climate change is affecting global rainfall patterns and water distribution. Since there is approximately 100 times more groundwater on Earth than fresh surface water, it makes sense to exploit groundwater as a source of water. The aim of this white paper is to share some of Denmark’s technologies, tools and methods for groundwater mapping and hydrogeological modelling.
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.
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.
Good rainwater management can make cities healthier places to live, resilient towards climate change and more sustainable overall. Population growth and urbanisation, floodings as well as more frequent and longer periods of droughts all encourage an optimised use of rainwater in cities. Traditionally speaking, climate adaptation seeks to lower the risks posed by the consequences of climate […]
