Optimal planning of water and wastewater management infrastructure for insular areas: the role of water reuse
The present article estimates the financial benefits of water reuse by calculating the annualised total cost of water and wastewater management, using mixed integer linear programming. The programme is using as input: geographical data, population distribution, and groundwater availability (for a given area), to calculate the qualitative localised water needs, and to estimate the sizes and ...

Analysis of challenges and opportunities to meaningful Indigenous engagement in sustainable water and wastewater management
Access to safe drinking water and adequate sanitation continue to be significant issues affecting Indigenous populations worldwide. The full participation of Indigenous peoples within water and wastewater policy and decision-making has been hindered by many factors, including capacity, inadequate resources and, overall, a lack of respect or formal recognition of Indigenous rights. This study ...

Sustainable wastewater management in developing countries: are constructed wetlands a feasible approach for wastewater reuse?
Water shortage is a major problem in many developing countries and represents one of the key factors for their development. The quality of available resources has deteriorated owing to pollution by lack of wastewater treatment facilities and control mechanisms/laws. Therefore there is a great need to propose appropriate wastewater management in developing countries. This paper summarises ...

Water and wastewater management technologies through the centuries
The aim of this paper is to propose a journey through the history of water and wastewater management technologies in the ancient civilizations, a sort of Appian Way (“Via Appia”, the “regina longarum viarum”) through the Centuries. Moreover, this paper is a sort of short summary of papers presented in the first two IWA Specialty Conferences on Water and Wastewater Technologies in Ancient ...

Water and wastewater management in the treatment process of a Roman
fullonica The aim of this paper is to study the treatment process of a Roman fullery (fullonica) with particular attention to the water and wastewater management system. Remains of several fullonicae have been documented at Pompeii and Herculaneum (Campania, Southern Italy), Ostia and Rome (Latium region, Central Italy), Florence (Tuscany, Central Italy), etc. The common academic perception of Roman ...

Assessing material flows in urban systems: an approach to maximize the use of incomplete data sets
Data scarcity and uncertainty are the main limiting factors for an integral evaluation of the urban water and wastewater management system (WWMS) in developing countries. The present research shows an approach to use incomplete data sets to analyse the flows of water and nitrogen and to make an integral evaluation of the WWMS at a case study city. By means of data validation and model ...

Major urban water and wastewater systems in Minoan Crete, Greece
During the Minoan era a number of remarkable developments occurred on the Greek island of Crete which have been widely recognized. However, one of the salient characteristics was the architectural and hydraulic function of its water supply, sewerage, and drainage systems in the Minoan palaces, cities, and other settlements. It might be inferred, therefore, that Minoan master craftsmen in Bronze ...

Development of monitoring and evaluation system for wastewater issues in Palestine
Wastewater is the main source of groundwater pollution if it is not properly collected and treated. In many parts of the Gaza Strip and the West Bank wastewater is collected through cesspits, while in other areas it is collected through networks and treated in central treatments plants. Collecting aggregate information on the level of indicators with concern to the wastewater issues (collection, ...

Redesigning wastewater infrastructure to improve resource efficiency
Resource efficiency of wastewater management is a question of optimizing at the same time the management of resources in wastewater (e.g. water), the resources spent on treatment and transport (e.g. energy), the natural resources to protect (e.g. the receiving waters), and the anthropogenic resources (e.g. capital). For instance, wastewater can be treated to any given quality, but only at the ...

A brief history of water supply and wastewater management in ancient Greece
The evolution of urban water management in ancient Greece begins in Crete during the Middle Bronze and the beginning of the Late Bronze Ages (ca. 2000–1500 B.C.) when many remarkable developments occurred in several stages as Minoan civilization flourished on the island. One of its salient characteristics was the architectural and hydraulic function of its water supply and sewerage systems in the ...

The River Segura: reclaimed water, recovered river
The Region of Murcia is located in southeast Spain, an area known for structural water stress. The most important water source that runs through the Region is the Segura River, which is the main irrigation water resource. Late last century there was a significant environmental problem in the Segura River caused by an increase of inadequately treated wastewater discharges, in a period of low ...

The Circular Economy and Wastewater: Closing the Loop for Sustainability
Traditionally, wastewater treatment has been focused on removing contaminants and pathogens to recover water and safely discharge it into the environment. However, the circular economy offers a new approach to wastewater management, one that views wastewater as a valuable resource rather than a waste product. In a circular economy, wastewater treatment plants become resource recovery ...

An integrated approach to water management in Kayseri: rainwater collection and use in an amusement park
Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and ...

Reducing water consumption in industry through flow analysis and simulation: a case study from India
Increasing water shortages in some countries is forcing the industrial enterprises to secure their own supply of process water. Reducing water consumption and closing water cycles is essential in order to safeguard industrial water supply. The various ways of implementing water saving measures in a company can be highlighted via a status-quo analysis involving a simulation of the actual ...

Optimal location of artificial recharge of treated wastewater using fuzzy logic approach
Increasing water demands in light of limited water resources have intensified exploitation and drawdown of groundwater. On the other hand, rising water demand has accelerated wastewater production. Therefore, urban wastewater management via artificial recharge may play a significant role in aquifer management. While site selection for artificial recharge projects is a major challenge, fuzzy ...

The potential for reusing treated municipal wastewater for irrigation in the Hashemite Kingdom of Jordan
This paper elaborates on the chemical composition of wastewater at selected Wastewater Treatment Plants (WWTPs) in Jordan. These plants have immense potential of providing reused treated water for irrigation. Samples from treated effluents analysed to study the efficiency of the impact of treated water on irrigation. The results revealed the effluents from WWTPs could be used for irrigation with ...
