Water conservation
Water conservation is the practice of using water efficiently to reduce unnecessary water
usage. According to Fresh Water Watch, water conservation is important because fresh
clean water is a limited resource, as well as a costly one. As a homeowner, you’re
probably already well aware of the financial costs of inefficient water use. Conservation of
this natural resource is critical for the environment — and our wallets
Need of water conservation and management
There is need for conserving water because:i. With a change in climate, the level of
groundwater is decreasing. This results in limited use of water because of the fallen level.
So, we should conserve water in order to increase the groundwater level and accomplish
the shortage of water when the underground water level goes down drastically.Ii. The
population is increasing day by day at an enormous amount and water sources are
decreasing. To prevent the scarcity of water we should conserve more and more water and
preserve it for the next generations as well.
Water Scarcity
The amount of water that can be physically accessed varies as supply and demand
changes. Water scarcity intensifies as demand increases and/or as water supply is
affected by decreasing quantity or quality.
Water scarcity assessments need to incorporate information on green water (soil
moisture), water quality, environmental flow requirements, globalization, and virtual
water trade. There is a need for collaboration between hydrological, water quality,
aquatic ecosystem
Causes
• Water pollution
• Groundwater over drafting
• Over use and misuse of water
• Diseases
• Climate change
• Human settlements
• Loss of groundwater
• industrial waste
Drought
Drought is a prolonged dry period in the natural climate cycle that can
occur anywhere in the world. It is a slow onset phenomenon caused by a
lack of rainfall. Compounding factors, such as poverty and inappropriate
land use, increase vulnerability to drought.
Multipurpose River Project
Multipurpose river valley projects are water resources projects planned for
various purposes like irrigation, hydropower generation, water supply for
drinking and industrial purposes, flood control, and navigation. These are
projects serving more than one purpose, playing a major role in the economy
and development of a country. It is commonly observed that the majority of
the multipurpose river projects in India are a combination of irrigation and
hydropower.
Rain water harvesting
Rainwater harvesting (RWH) is the collection and storage of rain, rather
than allowing it to run off. Rainwater is collected from a roof-like surface
and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer,
or a reservoir with percolation, so that it seeps down and restores the
ground water.
Chemical impact on treating water on environment
Water treatment reduces the volume of waste that is released into the ecosystem.
When wastewater is treated, the quantity of waste that is released into the
environment is cut down significantly resulting into overall improvement in the
environment’s status.
One of the biggest challenges of wastewater treatment is the diseases caused by
pathogens in the wastewater. When the wastewater is not treated properly, these
pathogens end up contaminating both surface and groundwater and this polluted
drinking water can result in several diseases.
Conclusion
We should understand the importance of water conservation from the
fact that now only 1% of water is left on earth. And if we continue to
waste it in this way, all the sources of water can be exhausted in future.
Water conservation includes all the policies, strategies and activities to
sustainably manage the natural resource of fresh water, to protect the
hydrosphere, and to meet the current and future human demand.
