“Water for the World”
Water: Who cares + why. How long can we live without water? Really?! How much do we need per day? Okay… How much do we use? 3 days 30 – 50 L 140 – 50 L What?! That is crazy! Where does it all go??? How long can we live without food? 3 weeks (In dire situations, like a refugee camp the standard for aid agencies is at least 15L – Source: Sphere Standards)
Where does it go? Drinking Cooking Shower + washing hands Flushing the toilet Gardening, washing the car etc. Where else is water used? Farming + Industry At home:
How much water do we use? Brushing teeth : Washing hands and face : Flushing the toilet : Having a shower : Having a bath : 1 L 4 L 19 L 35 L 80 L 140 L Blimey!
Where does your water come from?
Why can’t we drink straight from the River Cam? dissolved chemicals Particulates (small bits) micro organisms
Where does drinking water come from? Filter River “source” Add chemicals Stir Settle Disinfect Store Distribute
Is this a sensible system? Pros: - Good water quality - Managed supply - Easily regulated - Convenient-on tap - Highly centralized Cons: - Leaks - Taking out stuff we’re putting in.
Fail Proof? If this can happen in the UK, imagine what it is like to live in a developing country… North Wales Diarrhoea Crisis, 2005 –231 people infected!
Quick quiz… 1. How many people worldwide do not have access to clean drinking water? a) 100 million (about 1 in 60 people) b) 500 million (about 1 in 12 people) c) 1.1 billion (about 1 in 5 people) d) 3 billion (about 1 in 2 people) 2. How many times more water do we each use everyday, compared to a person in a developing country? a) 10 – 30 times b) 30 – 50 times c) 50 – 70 times d) 70 – 90 times C B 3. As a cause of death in children under 5, diarrhoea weighs in at number a) 2 b) 6 c) 10 d) 12 A – source: WHO – World Health Report 2005
Quick quiz… 4. What percentage of illnesses in developing countries are water- related? a) 10% b) 30% c) 50% d) 80% 5.How many people die everyday from diseases related to bad water? a) 100 - 1000 b) 1000 – 10 000 c) 10 000 – 100 000 d) 100 000 or more 6. What actions can reduce diarrhoea ? D C Improved water supply Improved sanitation Improved household water treatment Hand washing
Who here likes rain? Rain = Survival! Not everyone has the resources and technology to make drinking water like us.
School vs Heavy Water Buckets What’s wrong with that? Who most often collects water in developing countries? Women and children Education for women Time for employment Time for growing food In rural Africa 1/3 people have water within a 15min journey. For 44% it’s more than a half hour journey!
The Filtration Challenge! The Challenge -In groups, make a WORKABLE water filter -Each group = country - Follow the instruction sheet - Buy supplies from front -20 minutes ONLY! -Demonstrate filter at end.
Where are these countries?
The Filtration Challenge! The Rules: -Only 1 person per group buys at a time. -You can talk and deal with other groups. -No stealing! – Not that you would …
How does this relate to the real world? Activity Money Difference Illegible instructions Resourcefulness Countries share Real World - Based on actual country’s Gross Domestic Product (GDP) - Based on actual country’s illiteracy rate - Lack of education and access to information - People in poorer countries have their own ways of coping - Richer countries may offer “Official Development Assistance” (ODA) to poorer countries - Countries form groups like the G8, OECD, or Group of 24
The Real World In 2004, the UK donated 0.33% of GNI to aid yet UK had the 4 th highest GDP in the world and 10th highest GDP per person In 1970, countries agreed that 0.7% of GDP should go to aid Today, the average is 0.22% Okay, but that was A LIFETIME ago for most of us (sorry teachers). Surely we are doing better now! WE COULD BE DOING MORE! Say what?! What about us?
“Appropriate technology” It’s not just about giving money and technology… … it’s about using the best long-term solution for the problem! e.g. A Ferrari won’t last long in a desert (unfortunately)
Thinking about “technology” more broadly… Social Issues – Who wins + who loses? Cultural Issues – Some people see water as sacred. Training – Who will fix it? Cost – Can the local customers afford to buy and run it? Cheaper to make locally? Ownership – Are they going to care if everything is done for them? Is it going to last long?
What can we do to make a difference from Cambridge?
ActionWater saved 5L/min 5000L/person/year 300L/week But remember a long shower on full flow can use as much or more than a bath 140L/week 500L/week Turning off the tap when you brush your teeth or wash your face Free Flush Saving devices are available at: http://www.thames- water.com/waterwise Fix leaky taps in your home
