Rapid population growth in developing cities often outpaces improvements to drinking water supplies, and sub-Saharan Africa as a region has the highest percentage of urban population without piped water access, a figure that continues to grow. Accra, Ghana, implements a rationing system to distribute limited piped water resources within the city, and privately-vended sachet water-sealed single-...

Abstract As a disease, COVID-19 has shaken the world in 2020/21. Countermeasures have been taken by governments to protect against infection, which also affected water and energy consumption of buildings. In particular, buildings managed public authorities (e.g. kindergartens, schools administrative offices) closed reopened with different concepts. this paper, impact countermeasures on electric...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

river water is not only an indispensable source for irrigation but also plays a vital role for drinking water supply for most of the urban municipalities. water from rivers is pumped at specific sites and after treatment at municipal water treatment plants supplied as domestic potable water supply. the present study was undertaken to assess the suitability of gomti river water at gaughat being ...

Because surface water can be a source of undesirable water quality in a drinking water well, an understanding of the amount of surface water and its travel time to the well is needed to assess a well’s vulnerability. Stable isotope ratios of oxygen in river water at the City of La Crosse, Wisconsin, show peak-to-peak seasonal variation greater than 4‰ in 2001 and 2002. This seasonal signal was ...

Many copper water lines for municipal drinking water in Santa Fe, New Mexico USA, have developed pinhole leaks. The pitting matches the description of Type I pitting of copper, which has historically been attributed to water chemistry and to contaminants on the copper tubing surface. However, more recent studies attribute copper pitting to microbial induced corrosion (MIC). In order to test for...

AIMS Molecular procedures were used to identify Thiothrix spp. in biofilms from sulphide-rich waters in two distinct ecosystems. METHODS AND RESULTS Biofilm samples were obtained from two groundwater-fed systems in central and northern Florida, including an artesian spring and municipal water tank. The 16S rDNA in each sample was directly amplified by polymerase chain reaction. CONCLUSIONS ...

Man has always been proficient producer of waste; however, towards the end of the 20th century saw the upsurge of a new, noxious clutter: the electronic detritus that has come to be known as e-waste. The consumption of electronics: televisions, computers, cell phones, video games, iPods, etc has increased over the last few years, making the electronic industry the world’s largest and fastest gr...
