White papers

The consulting companies, technology providers, research institutes, water utilities and governmental bodies in the Rethink Water network developed a series of white papers to provide customers, researchers, politicians and others with insight and give guidance on important water related topics. The white papers share examples of water solutions in Denmark and around the world. The people contributing are listed with e-mail address on page two.

WATER SUPPLY In addition to meeting emerging needs for increased resource efficiency and customer demands for uninterrupted service around the clock, water utilities can also benefit from improving the quality of the water supplied to their customers. If citizens and industry prioritise water of high quality over low water rates, water utilities will be able to afford the new investments required. Water utilities in Denmark are clear proof of this.
RECREATIONAL WATER Most of the technologies used for swimming pools and water parks have hardly changed in the last 100 years. Chlorine is the best way to make sure the water is free of unhealthy bacteria, but using large quantities is no longer always necessary. By rethinking water treatment and ventilation concepts, the chlorine content can be greatly reduced. This protects people from the smell and itchy eyes, and at the same time paves the way to big savings in operational costs.
INDUSTRIAL WATER The world’s oceans, lakes and rivers are no longer an unlimited source of human food because many of the world’s fish stocks have been fished to their limits or are on the verge of collapse. This encourages the aquaculture sector to grow, but if aquaculture farms are poorly located or poorly managed they have the potential for significant negative impacts on the environment. An ever-increasing demand for fish thus calls for more sustainable and more efficient solutions.
WASTEWATER Globally less than one fifth of all wastewater receives proper treatment, affecting people's health and causing severe environmental degradation of many inland and sea waters. Wastewater is a valuable resource as organic contents can be transferred to energy, phosphorus recycled, heat recovered and treated wastewater used for irrigation or cooling.
WATER RESOURCES Providing enough fresh water for a growing population and for increasing industrial production is a critical issue in many countries. 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
WATER SUPPLY For many water utilities it is important to close the considerable gap between the volume of water they supply and that which is billed to the customers. This difference is known as Non-Revenue Water (NRW) and it amounts to between 25 and 50 percent of the total water distributed globally.
WATER RESOURCES The conflicting interests of nature and the different sectors involved in sharing limited water resources must be addressed in an integrated fashion at both policy and operational level. Water resources management authorities all around the world have found help in the principles of Integrated Water Resources Management (IWRM)
URBAN WATER Today’s urban population of 3.2 billion will rise to nearly 5 billion by 2030. Added to this, many cities face pressures of rising sea levels and extreme weather events, bringing with them the risk of flooding and periods with little water. These challenges present the opportunity to rethink urban development and gain greater value from every cent invested
INDUSTRIAL WATER The availability of water will be a critical issue in the future, and the cost of water will rise. Nearly three-quarters of water consumption in the world relates to the consumption of food and drink. Frontrunners who work to speci­fic­ and measurable targets with respect to reducing their water footprint can turn water efficiency into an advantage
