In this study, we investigate numerically, using EPANET code, the leaks in the water distribution network (WDN). The old part of Casablanca city (Morocco) is used as a case of study. The first episode is based on a simulation of artificial leaks on the MATLAB platform using the EPANET. The second was a real simulation of artificial leaks. The results obtained are compared with those of real simulation of artificial leaks caused by the opening and closing of hydrants.

One of the crucial aspects of developing forward osmosis (FO) process is making a suitable membrane. In this work, an FO membrane was synthesized by making a polyamide selective layer on an electrospun nanofibers support layer. The prepared thin film composite (TFC) membrane showed good performance in terms of water flux and salt rejection compared to the commercially available membranes. Also, it showed good properties for FO membranes, namely porosity, hydrophilicity, and mechanical strength.

Providing potable drinkable water from saline or heavily polluted water using renewable energy has been further explored. Solar desalination, an eco-friendly, readily accessible and affordable technology. We have shown that there is a direct relationship and huge dependency of solar still daily distillate yield on the solar radiation intensity and the temperature difference between the condensing inner glass cover and the water. Hope of drinkable water for all through solar powered technology.

This study is to prepare a cellulose paper was impregnated with silver nanoparticles (AgNPs) for the purpose of water purification (Disinfection (removal of several types of bacteria) and filtration). Sliver nanoparticles used in this work exhibit a broad size distribution with highly reactive facets. AgNPs paper provided rapid and effective bactericidal activity as the bacterially contamination.

This study analysed the impact of an extreme weather event, water quality deterioration and a growing drinking water demand on the sustainability of drinking water supply in the Netherlands. The results of the case studies were compared to sustainability issues for drinking water supply that are experienced worldwide. This resulted in a set of sustainability characteristics, describing drinking water supply on a local scale in terms of hydrological, technical and socio-economic characteristics.

Access to clean and safe drinking water is a basic human right. Poor quality of drinking water is directly associated with various waterborne diseases. The study found that people living in rural areas, headed by aged ones and having large family sizes are significantly less likely to use safe drinking water sources and households having media exposure, education, women empowerment in household purchases and belonging to the rich segment of society are more likely to use safe drinking water.
