Water Reuse is a topic which is gaining attention day by day.The reason behind the interest is the climate change, urbanization and its impact on available water. As source and amount of water that can be treated is constant the growing demand from the ever-growing population has raised the stress on available water resources of any region manifold. Due to change in climate, amount of rainfall is now either over or under the level of requirement.This abnormality in the rainfall pattern and also the uncontrolled use of natural resources by the population for their earthly gains, has reduced both quality and quantity of water available for consumption.In these regard, the reuse of water is found to be a suitable and acceptable option to somehow mitigate the uncertainty. As the concept of reusing water is not new, but its real importance has recently been understood,doing research in this concept can be beneficial for both mankind and the researcher himself.

  ( Image Source ) The reclamation of water from waste-water in a planned or unplanned manner is known as Water Reuse. The waste or excess water from any system can be treated and reused. Types of Water Reuse This treated water can be used for watering plants,cleaning and washing, irrigation, recharging groundwater, filling up swimming pool or garden ponds and even for drinking. If the water is reclaimed for potable purpose then the process of reuse can be seperated into three different strategies : 1.Indirect Potable Reuse(Planned) : "The reclamation and treatment of water from wastewater (usually sewage effluent) and the eventual returning of it into the current/natural water cycle well upstream of the drinking water treatment plant. Planned reuse indicates that there is an intent to reuse the water for potable use."( Source ) 2. Indirect Potable Reuse(Unplanned) :  The treated waste-water often inadvertently get injected into

The installation of drip irrigation system cost around Rs 1.25 lakh per hectare.The cost for maintenance is also high.This type of system incurs water to the crop in drip manner so that soil moisture can be kept at optimum level most of the time. A farmer in Madhya Pradesh has reduced the cost of drip irrigation to about Rs.2500 by using saline bottles as droppers,a storage tank to store water and some plastic pipes for bringing the water to the dripper. Such innovative applications of waste materials can save money as well as reduce the necessity of disposal which is now a big issue in the western world. Read the full news for more detail .

King tides which was a irregular phenomena in Miami is now seems to be a regular one.The experts are blaming the climate change for this.But a phenomenna like this which  is caused by gravitational force without the assistance of rainfall. How climate change can effect that ??? One reason can be attributed to the increased frequency of storms and rainfall;rise in sea level which is influenced by the climate change can add to the tidal flow.The erosion in the river banks and the sedimentation that may have reduced the depth of the water canals  can also attributed for this frequent king tides not only in Miami but also in the other places of the World. But still blaming only the change in climate for king tides is not justified. Read the news
