Problems and Solutions for a Sustainable Water Supply
International Sustainability Leadership Project
Presentation Topics
Conservation Water Quality
Transportation Storage
Hydrologic cycle describes the continuous movement of water
The Water Cycle
Several layers of complexities added to that cyclical process
Global water resources and usage
•3% of our global water resource is freshwater (majority of what humans use)
•Of that 3% of usable freshwater, 70% is used for irrigation, 22% for Industry, and 8% for domestic use
Major Problems of Water Transportation
- Water is heavy - Becomes unsanitary - Underground pipes
disturb the earth - Over ground pipes
disturb wildlife, and human livability.
- Very expensive to build pipes.
The uphill battle
Problem Carrying water uphill requires regular pumping
stations along the route. - These cost money to build. - Needs constant energy to power stations.
Solution - Build denser communities downhill, instead of
building up on high hills. - Use gravity
Carbon Emissions of City of Beaverton’s water system
Purchased Electricity
68%
Fleet15%
Commuting11%
Natural Gas3%
Air Travel3%
(85% of this is for pumping)
The leaks of water
Leaks
- As the water travels through the pipes, they leak. - Pipes and pipe systems are old and inefficient. - The older countries that have had the system for
a long time have the worst problems. - Water utilities need to have a system of checking
leaks, making sure no water is being lost. - Government needs to fix the biggest/longest
water pipes.
City Planning
- Building homes next to businesses reduces how far water needs to travel.
- Mixed use buildings (shops, homes, offices) are best for keeping water in one area.
- Having everyone reuse drinking water for toilets, etc, reduces the need for water to travel again and again.
- Planning cities around rivers, lakes, other large bodies of water
Some innovative ways of
transporting water
Roman Aqueducts
Natural Inland Waterways
“HippoRoller”
“Aquaduct”
Sanitation
- Rivers are becoming increasingly polluted, by residents, businesses, and industries.
- The air is polluting the rain coming down, which falls into the rivers.
- Not every city has efficient water sanitation departments and what a water sanitation department can do is limited due to the pollution.
Conservation & Quality
Rebates - Toilets - Dishwashers and
Washing Machines
- Irrigation Improvements and Controllers

Closed-loop water management
Managing water quality
-Drinkable - Clean without toxins And keep the quality throughout the transport system. -So we treat them!
Storage
Summer Peak Usage
Groundwater
- 96% of drinking water on Earth
- Between 25 & 40% of the water used
- Two main problems: - Pollution of the ground - All the ground water is
not renewable
Store Rainwater at Home and Business!
The best way to use rainwater is for landscape irrigation.
Example of industrial use of rainwater: server farm
