In view of high population growth and water resources deficit in arid and semiarid area and groundwater resources shortage in mountainous area, there is an urgent need to identify the alternative sources of potable water. Fog is one of such sources of water. Although fog water yielding potential is largely ignored by water authorities, it was used extensively in ancient times and promoted the water productivity. The objective of this research is to review the fog collection in Yemen and South Africa. In El Tofo Mountain in Chagungo (Chile), 75 fog collectors were erected. According to the reports, production rates vary from zero on a clear day to maximum of 100000 liter per day. With this arrangement, each of the 330 villagers received about 33 liter of clean water per person per day. Geographical and climate characteristics, droplets distribution, and fog density need to be evaluated and are crucial factors for success of fog water harvesting project. Chemical and microbial studies of fog water harvesting show that the water quality is safe for human consumption. Thus, it can be considered as an alternative source of water in arid and semi-arid regions that dense fog could be available.

Nowadays water resources protection, by application of optimized, sustainable and economical approaches, for logical utilization of water has turned to one of the most vital and challenging issues worldwide. Additionally, water reuse, known as a strong factor in managing water crisis, is an appropriate alternative to handle this challenging crisis. This senior project discusses the design and construction of a solar water treatment system taking the advantage of ultraviolet (UV) radiation and a combination of natural processes. An UV wastewater treatment system is designed to demonstrate the wastewater treatment capability of the network. This system is specifically designed to eliminate bacterial contaminants and meet the needs of a community. Only sunlight is needed to power the treatment system. A solar panel collects energy from sunlight to be used for electrical consumptions such as pumping. Ultraviolet light disrupts bacteria and produces a source of drinking water. In fact, we try introducing an innovating idea of a decentralized solar wastewater treatment (DSWWT) machine, which is adaptable with environmental standards goals. In addition to being affordable and eco-friendly, it can be used in different kinds of communities (especially useful for remote communities).This machine will also be capable of being used in any residential, commercial or official building, which produces wastewater. Based on the assessments, manufacturing of this machine is easily reachable.
