1. Benefits environment
Since all the water waste is released in natural water reservoirs such as lakes and rivers, the water gets contaminated. This polluted water is consumed by fishes, crops, and animals. Also, the polluted water is evaporated and ultimately the rainwater is also nothing but polluted water.
2. Recycled water
Since factories and industries require a huge amount of water every day for different processes, water recycling is the best solution. Any water waste treated by plants is pure enough to be utilized again. This process saves hundreds of liters of water.
3. Energy production
The sludge collected during the wastewater treatment process contains a large amount of biodegradable material. These materials can be used to generate electricity and other energy. The energy generated here can be used in wastewater treatment plants making it self-sustainable.

The Realities of Water Usage
Location Impacts Usage
- A person’s location also impacts water consumption. In a drier climate, people water lawns to keep the grass from dying. That drives up usage. Farms often use irrigation systems on their crops, which also drives up usage. In those regions, more water gets used. Rain and snowfall may not replenish public water sources fast enough.
only Some Precipitation Makes It to Water Sources
