Water Conservation

Water Management Projects

1. Dams: • Agriculture• Recreation • Hydroelectric power

Water Management Projects

2. Canals and Irrigation Systems– Rerouting water

Water Management Projects

3. Reuse of water– Recycling water– Wastewater treatment plants

Wastewater

• Water that has been drained out of homes and businesses that gets cleaned and recycled– Sinks– Bathtubs– Toilets– Dishwasher– Washing machines– Rain gutters

Common Contaminates

• Human waste• Oils• Soaps• Chemicals• Food scraps

Wastewater Treatment• The process of removing contaminates from used

residential water

Desalination• The process of removing salt from sea water– Used on cruise ships, military ships and in

countries that do not have access to freshwater supplies

1. Vacuum Distillation • Boiling water to remove salt• Water evaporates off and is collected and salt

stays behind

2. Reverse Osmosis• Pushing water through a filter that does not

allow the salts to pass through

Pros• Supplies freshwater to places in the world that

do not have enough freshwater

Cons

• Uses a lot of energy• Costs a lot of money• Uses up land resources• Excess salt is harmful to

marine ecosystems

Xeriscaping• Landscaping and gardening in

ways that reduce or eliminate water use

Native plants to Utah

• Gamble Oak• Utah Juniper• Sagebrush• Prickly Pear• Quaking Aspen• Pinion Pine• Cottonwood• Heartleaf Arnica• Aster
