Waterborne diseases
Water pollution
Food production
Factors that increase water consumption (4)
Increased population (more needs)
Modern technology
Commercial agriculture
Infrastructure (HICβs can afford pipelines)
3 methods of increasing water supply
LARGE SCALE
Dams & reservoirs
Water transfers
Desanilation
CASE STUDY (LARGE SCALE)
Water transfer scheme
GREAT MAN MADE RIVER - LYBIA
Provides water security to the very dry area (transports water an aquifer to big cities like Tripoli)
- 6.5million m3 water per day β
- 70% water work done by Libyans β
- phase 1/5 cost $14billion β
- targeted by NATO warplanes in the war β
3 methods of sustainable management (SMALL SCALE)
Water conservation
Eg. Dual flush toilets
Groundwater management
Water recycling
- rainwater harvesting
- clean/grey/black water
CASE STUDY (SMALL SCALE)
Wakel River Basin Project
Rajasthan, India
It is a local scheme that aims increase water supply becauseβ¦
(Also aims to educate π©βπ« locals)
βover abstraction of aquifer (dependent)
βhot dry climate
β10/150 wells in one village have clean water
- TAANKA
Underground water storage (collect and store water)
β Simple and cheap
- walls fortified with lime to prevent water seeping into soil (waterproof & antibacterial)
- underground so its cooler
- cover stops sun evaporating - Pat system
Divert water from mainstream into crop fields for irrigation
- the small dam = bund and is made from accessible sticks and leaves - Johed
Small earth dams to collect rainwater which prevent rivers drying up
