The flows of wastewater originating from the water supply of a community and runoff from precipitation on urban surfaces are typically collected and conveyed for treatment and disposal. The system used for this purpose is called a sewer network or a collection system that consists of individual pipes (sewer lines) and a number of installations, such as inlet structures and pumps, to facilitate collection and transport. The efficient, safe and cost-effective collection and transport of wastewater and urban runoff have been identified as key criteria to be observed. In this context, the word safe means that public health, welfare and environmental protection have high priority. The demand for solutions toward more sustainable water management in the cities is a new challenge. 

Against this background, a sustainable and integrated dimension of wastewater management in sewer networks is needed. The safe and efficient collection and conveyance of wastewater to treatment and disposal are still main concerns. The consideration of sewer processes as an element in the design and operation of sewers will give anew dimension to the overall objective of sewer management and contribute to improved sustainability. Therefore, the technical systems must be considered holistically ... 

In-Sewer Processes and Sustainable Urban Wastewater Management... 

It must be realized that urban wastewater management is difficult to cope with in a sustainable way, because the entire idea is to use resources and pollute them In spite of this, the sustainable development of the urban infrastructure must be seriously considered, particularly because the centralized idea behind the urban water cycle, without doubt, will exist for an unknown future. 

Briefly expressed, the sustainable approach of the sewer process concept can be interpreted by changing wastewater management from an end-of-pipe treatment to a pipe and plant treatment. This is not the only way of approaching a sustainable solution for an urban wastewater system, however, it is a contribution. But, it is certainly true that the sewer process concept tends to put much more focus on the dry-weather performance of the sewer than is typically done. 

Human activities and the connected water usage lead to a variety of anthropogenic influences on DOM. The many years of careless exposure of rivers and lakes to untreated and not sufficiently treated wastewater from production sites and households have led to a severe load of the aquatic systems with inorganic, organic, and industrially synthesized products. Their effective elimination has turned out to be a high challenge and has become the key for sustainable water management.

The increasing awareness on the issue of water sustainability has stimulated new interest in the development of advanced technologies for water treatment and in the use of solid catalysts to increase their performance, manageability, eco-sustainability and/or reduce their cost. Due to the large variety of wastewater situations in terms of composition and flow rate, a range of different and/or combination of different technologies, is required. 

If wastewater purification and reuse are the necessary stage toward the sustainable water source management, the production of potable water directly from saline water sources is essential for increasing consistently the amount of available good-quality water. Harvesting water from the sea, lakes, and rivers, by an economically affordable way, is the potential straight and definitive solution to water shortage problems.

The book series addresses novel technigues and measures related to sustainable water developments with an interdisciplinary focus on different fields of water resources assessment and management, freshwater production, water and wastewater treatment and wastewater reuse as well as water-efficient technologies and water-saving measures. Particular attention is paid to the role of water issues within the water-energy-food-public health-ecosystem-climate nexus.
