The steady increase of urban population and the possible effects of climate change that may adversely affect the amount of water available in current water supply systems, makes the study of stormwater and rainwater harvesting and wastewater recycling a high priority. The basic proposition is that any system of water supply that can reduce the amount of water drawn from main reservoirs will be ...

Groundwater is one of the most important water resources especially for irrigation in the east of Iran. So, it is important to note its water quality variation for deciding to manage it. To this end, the study were done to zone Birjand plain located at latitude between 32˚ 30’-33˚ 00’ N and longitude between 58˚ 45’-59˚ 41’ E. In order to achieve this goal, the required layers, Sodium adsorptio...

This study was conducted to assess the bacteriological quality of alternative drinking water supply options in southwest coastal areas of Bangladesh. A total of 90 water samples were collected during both dry and wet seasons from household based rainwater harvesting systems (RWHSS), community based rain water harvesting systems (CRWHSs), pond-sand filters (PSFs) and ponds. The samples were eval...

Urban rainwater reuse preserves water resources and promotes sustainable development in rapidly growing urban areas. The efficiency of a large number of urban water reuse systems, operating under different climate and demand conditions, is evaluated here on the base of a new risk analysis approach. Results obtained by probability analysis (PA) indicate that maximum efficiency in low demanding s...

Solar distillation is an appealing and facile technology for seawater desalination water purification, but constructing stable, environmentally-friendly, cost-effective solar evaporators often remain unfeasible. Here, amyloid hybrid aerogels are introduced universal renewable freshwater production by relying on the combination of sustainable materials energy, thus making process highly ecologic...
