1) What are the ways of preserving water resources? 2. Give and write 2possible ways to prevent improper use of wastage of water in: a.) Industrial b.) Agricultural c.) Domestic

1) The ways of preserving water resources are:

• Stopping encroachment of humans/urban areas into the coverage areas of rivers and lakes.
• Stopping intrusion of solid wastes, liquid wastes & chemical pollutants into river and ocean waters.
• Reducing the emission of carbon dioxide so that global warming will get slower and melting of Mountain glaciers will reduce.
• Banning illegal cutting of plants and forests so that many freshwater resources can be preserved.
• Increasing natural recharge of the groundwater applying innovative approaches and through individual efforts.
• Utilizing a rainwater harvesting system so that less use of groundwater can be done.
• Development of different crops that uses less water for irrigation purposes.
• Initiating water conservation awareness programs in each school throughout the world.

Step-by-step explanation

2) a) The possible ways to prevent improper use of wastage of water in the industrial sector are:

• Removal of industrial contaminants through wastewater treatment plants and recycling these waters for agricultural purposes or injecting these contaminant-free waters the underground.
• Use of water expelled from juice/food factories into other works in the industry such as dishwashing purposes or in textile industries.

2) b) The possible ways to prevent improper use of wastage of water in the agricultural sector are:

• Implementation of cycling of water irrigation (chain or water irrigation) in the field by connecting each water field with neighboring fields so that excess water in peak rainfall season can be utilized wisely.
• Using excess /wastage water in one crop to irrigate other large fruit plants such as excess water from rice fields can be used in irrigation of banana plants or in jackfruit trees etc. Also, wasted water can be used for natural groundwater recharging purposes so that the water table can be maintained in a stable position.

3) The possible ways to prevent improper use of wastage of water for domestic purpose are:

• Using water from the bathtub and water basins to flush the toilet.
• Using wastewater from the kitchen for gardening and farming purpose so that water can be recycled.
• Also, applying the rainwater harvesting system during rainfall time so that we can use such water in winter and peak summertime so that rainwater may not go wasted.
