Water waste or wasting water is any water that has been affected by human use. Wasting of water means causing or permitting discharge of water without any practical purpose. Water is used in many combinations of domestic, industrial, commercial or agricultural activities. Wastewater refers to all effluent from household, commercial establishments and institutions, hospitals, industries and so on. It also includes stormwater and urban runoff, agricultural, horticultural and aquaculture effluent.
Types of wastewater:
- Blowback water: Wastewater produced by hydraulic fracturing.
- Groundwater: Water flowing underground, which discharges in a waterway.
- Process Water: Water generated in manufacturing or treatment processes; examples wash racks and pump & treat.
- Produced Water: Water that is from water-based oil and gas exploration.
- Stormwater: Water generated from a rain event.
Waste water treatment:
Wastewater can be treated in wastewater treatment plants which include physical, chemical and biological treatment processes. Water that is no longer needed or is no longer suitable for use in bilge water that can be discharged back into the environment and it is formed by a number of activities including bathing, washing, using the toilet and rainwater runoff. Wastewater treatment is a process used to convert wastewater into an effluent outflowing of water to a receiving body of water that can be returned to the water cycle with minimal impact on the environment or directly reused. The principal objective of wastewater treatment is generally to allow human and industrial effluents to be disposed of without danger to human health or unacceptable damage to the natural environment. Wastewater treatment, also called sewage treatment, the removal of impurities from wastewater, or sewage, before they reach aquifers or natural bodies of water such as rivers, lakes, estuaries, and oceans.
Overuse of water:
Overuse of freshwater in household settings means there is less fresh water for agricultural use which affects humans on a food scarcity level, but many livestock species rely on freshwater. While desalination plants can produce fresh drinking water, but they require a lot of energy, so wasting any water coming out of these plants wastes energy. Yes, it is bad. The water you have used must be treated in a sewage works before being released into the environment. Although water is essential for all businesses and organizations but by wasting water the business can contribute to water scarcity locally, nationally and even globally. Extracting too much water from underground reserves can also be damaging.
- Saving water should never become a public concern.
- A significant amount of freshwater is used for irrigation, yet the efficiency with which water is used in this sector is lower than 35%.
- More than 70% of the freshwater available to us in the form of groundwater and surface water is contaminated.
- Thermal and nuclear power plants require huge quantities of fresh water for power generation. But most of them don’t disclose the amount of water that’s utilized.
- You’ll be shocked to hear that Kolkata wastes 50% of the water that it receives!
- Bangalore, which is the third most populous city in the country, comes a close second at 49%. The wasted water is unaccounted for, which is even worse.
- Water wastage figures in New Delhi, Chennai and Mumbai stand at 26%, 20%, and 18% respectively.
