<div> <p>Digital solutions open up a variety of opportunities for the water sector. Digital water is now seen not as an ‘option’ but as an ‘imperative’ (Sarni et al., 2019) for a more sustainable and secure water management. Many solutions leverage the latest innovations developed across industries and business activities including advanced sensors, data analytics and artificial intelligence. The potential of digitalization might outweigh its associated risk if digital solutions are successfully implemented addressing a series of gaps and barriers such as ICT governance, cybersecurity, data protection, interoperability and capacity building.</p> <p>Within this context, the H2020 innovation project digital-water.city (DWC) aims at boosting the integrated management of waters systems in five major European cities – Berlin, Copenhagen, Milan, Paris and Sofia – by leveraging the potential of data and digital technologies. Goal is to quantify the benefits of a panel of 15 innovative digital solutions and achieve their long-term uptake and successful integration in the existing digital systems and governance processes.</p> <p>One of these promising technology is a new sensor for real-time bacterial measurements, manufactured by the company Fluidion (ALERT System; Angelescu et al., 2019). The device is fully autonomous, remotely controllable, installed in-situ and allows rapid quantification of E.coli and enterococci concentrations.</p> <p>Ensuring microbial safety is one of the key objectives of bathing water management, and it is also a critical aspect for water reuse. The European Bathing Water Directive (BWD) (76/160/EEC, 2006) uses fecal indicator bacteria for quality assessment of marine and inland waters. A major challenge regarding bathing water management is that concentrations of fecal bacteria may show spatial and temporal variability. In urban rivers, discharges from CSO and stormwater may contain high amounts of fecal bacteria and contaminate bathing water quality. Bathing water surveillance in Europe is only based on monthly grab samples and event-scale variability is detected only by chance as pollution events may occur between sampling intervals.</p> <p>The ALERT System is currently tested in Berlin and Paris using side by side laboratory comparison to understand temporal variability and spatial bacterial distribution in the local rivers (Seine, Marne and Spree). In Milan, the system is being deployed to provide early warning of bacterial and toxic contamination linked to water reuse at a major wastewater treatment plant. Preliminary analysis have shown that the device shows metrological capabilities comparable to those of an approved laboratory using MPN microplate techniques and is suitable for bacterial pollutant concentration ranges such as urban streams and wastewater treatment plant.</p> <p>The technology opens up new opportunities for the water sector for a range of applications such as the planning of pollution reduction measures, the continuous monitoring of bathing water quality and the assessment of contamination risk by the reuse of treated wastewater for irrigation. In particular, it is a key innovation to contribute to the objective of Paris city and other local municipalities to provide permanent and safe opportunities for bathing in the Seine river for the 2024 Olympic and Paralympic Games, and beyond.</p> </div>

This paper depicts the research conducted at a micro-pilot scale on autochthonous cultures in order to develop adequate technological solutions for the treatment of wastewater resulting from shrimp cultures (Palaemonidae) that would ensure the protection of the Black Sea ecosystem and constitute an applicable tool for the development of aquaculture in Romania. The proposed objectives were attained by adopting an integrated system of marine cultures shrimps-mussels-macrophyte algae, followed by a conventional chemical treatment step using aluminium sulphate recovered from metallurgical slags. This system together with wastewater treatment ensures an optimum development of species and a minimum load of pollutants in the aquatic environment.

The City of Baltimore, Maryland is one of many US cities faced with challenges related to increasing potable water demands, diminishing fresh water supplies, and aging infrastructure. To address these challenges, the City recently undertook a $7M study to evaluate water supply and treatment alternatives and develop the conceptual design for a new 120 million gallon per day (MGD) water treatment plant. As part of this study, an innovative raw water management tool was constructed to help model source water availability and predicted water quality based on integration of a new and more challenging surface water supply. A rigorous decision-making approach was then used to screen and select appropriate treatment processes. Short-listed treatment strategies were demonstrated through a year-long pilot study, and process design criteria were collected in order to assess capital and operational costs for the full-scale plant. Ultimately the City chose a treatment scheme that includes low-pressure membrane filtration and post-filter GAC adsorption, allowing for consistent finished water quality irrespective of which raw water supply is being used. The conceptual design includes several progressive concepts, which will: 1) alleviate treatment limitations at the City's existing plants by providing additional pre-clarification facilities at the new plant; and 2) take advantage of site conditions to design and operate the submerged membrane system by gravity-induced siphon, saving the City significant capital and operations and maintenance (O&M) costs. Once completed, the new Fullerton Water Filtration Plant (WFP) will be the largest low-pressure membrane plant in North America, and the largest gravity-siphon design in the world.

A computer program based on expert system software was developed and proposed as a prototype model for water management to control eutrophication problems in receiving water bodies (Suzuki etal., 1988). The system has several expert functions: 1. data input and estimation of pollution load generated and discharged in the river watershed; 2. estimation of pollution load run-off entering rivers; 3. estimation of water quality of receiving water bodies, such as lakes; and 4. assisting man-machine dialog operation. The program can be used with MS-DOS BASIC and assembler in a 16 bit personal computer. Five spread sheets are utilized in calculation and summation of the pollutant load, using multi-windows. Partial differential equations for an ecological model for simulation of self-purification in shallow rivers and simulation of seasonal variations of water quality in a lake were converted to computer programs and included in the expert system. The simulated results of water quality are shown on the monitor graphically. In this study, the expert system thus developed was used to estimate the present state of one typical polluted river basin. The river was the Katsura, which flows into Lake Sagami, a lake dammed for water supply. Data which had been actually measured were compared with the simulated water quality data, and good agreement was found. This type of expert system is expected to be useful for water management of a closed water body.

This paper examines the administrative and legal structure of the wastewater sector in Turkey, identifying its shortcomings and their causes, and suggests solutions. The study begins by outlining the existing administrative and legal structure, then focusing on the areas where difficulties are faced and seeking solutions to them. Those administrative and legal facets which have produced improvements and/or function effectively have been analysed so as to provide examples for other areas. When examining the sector it was observed that problems common to every area are the failure to adequately define powers and responsibilities, the lack of coordination between sectoral organisations, and the fact that attention is generally concentrated on routine matters of secondary importance. The fact that numerous organisations share powers in the same area causes confusion. Plurality also creates difficulties where enforcement is concerned. The existence of more than one set of regulations relating to the same area gives rise to loopholes. At the same time, unrealistic, and hence unenforceable standards undermine the effectiveness of sanctions. It has been concluded that a single organisation should be invested with the legal powers to lay down the principles of water management, that environmental courts should be set up to enforce legislation by means of sanctions; and that for this purpose existing legislation should be reexamined and revised as necessary and/or brought up to date.

Significant damage to surface water is caused by cattle husbandry. Only one global approach of water management and farming techniques (breeding management and cultivation methods) will ensure significant results. A pilot study run in the west of France proved that water quality can easily be improved by renovating the cattle buildings. It also showed that manure used as a fertilizer covers cultivation needs, which allows substantial savings for the farmers.

Until the last two decades, the global perception of how to control our various water bodies was remarkably similar – water management was organised on a sectoral basis, as it always had been. It was only in the 1970s that the people actually responsible for implementing water management began to become aware of the serious implications of such an approach: water quality deterioration, desiccation and an alarming loss of the flora and fauna that characterised their local water environment. It was a growing awareness that led to the formation of the concept of integrated water management, a concept almost universally accepted today as the way forward. However, despite the fact that few dispute the validity of the concept, a number of obstacles remain before this theoretical agreement can be transformed into practical action. Three main bottlenecks stand in the way of implementation: institutional, communicational and socio-political. Whilst solutions to these are available, the key question still to be answered is whether society is really prepared to accept the consequent changes in the way we live that will result from putting the theory of integrated water management into practice. It was this issue that dominated the “Living with water” conference held in Amsterdam in September 1994. The following is a summary of the discussions held there and the various papers that were submitted.
