  1. 1. SAVE OUR WATER!<br />
  2. 2. Water Conservation in<br />Schools <br />
  3. 3. Water<br /><ul><li>Water – In Ireland
  4. 4. Water – The World view
  5. 5. Water in your school</li></li></ul><li>Ireland’s Water – Availability <br />Nationally <br />Highest rates of rainfall in Europe<br />Enough water to meet our/environment’s needs <br />FOR NOW<br />Regionally <br />Variations in climate East and West <br />Greater population density in the East – greater demand<br />Some areas experience water shortages in warmer weather <br />
  6. 6. Ireland’s Water – Rainfall Distribution<br /> Rainfall in Ireland is higher in the West than in the East <br />Eastern Ireland <br />750 mm – 1000 mm per/yr<br />Western Ireland <br />1000mm – 1250 mm per/yr up<br />to 1500mm in coastal areas <br />
  7. 7. Ireland’s Water – The Future <br />High temp levels/ sunshine rates impact water supply <br />Increased evaporation reduces water in rivers/lakes <br />Climate change to alter distribution of rainfall <br />Drier Summers and wetter Winters – in the East<br />More water shortages/flooding<br />
  8. 8. Ireland’s Water – Water Quality<br />Declining Water Quality <br />Population Growth<br />Intensive Agriculture<br />Growth of Urban Centres<br />Rural Development <br />
  9. 9. Ireland’sWater – Water Quality <br />Eutrophication<br />Caused by run-off of <br />fertilisers, sewage, slurry <br />“Probably Ireland’s most<br />serious pollution problem”<br />.... EPA <br />Leads to fish kills <br />
  10. 10. Ireland’s Water – Water Quality<br />Ground- Water Pollution<br />Contamination by<br /> pathogens <br />Spreading animal waste<br />Failing septic tanks <br />Spread of Invasive species <br />Zebra Mussel/Chinese Mitten Crab <br />
  11. 11. How much of earth’s water can we use? <br />
  12. 12. Water – The Global Picture <br />Less than 1% of the world’s supply of water is suitable for drinking<br />Increasing challenges to people, livelihoods and ecosystems, due to pollution, climate change, over population and mismanagement<br />The world's population in 2008, at over 6.6 billion, is growing by about 80 million people each year <br />1.1 billion people in the world do not have access to clean drinking water <br />
  13. 13. Water Shortages – Australia <br />Murray-Darling River Basin <br />One-million sq/kms<br />Basin holds two-thirds of country’s irrigated lands<br />Rice paddies, cotton fields, vineyards, wheat praries, cattle pastures<br />Australia’s ‘bread-basket’<br />40 % of the country’s agricultural output <br />Valued at $ 10 billion/yr <br />
  14. 14. Water Shortages – Australia <br />Climate Change <br />Temp increase of .75 degree C over past 15 years<br />A 7 year drought in the river basin district <br />Surface flows cut by 40 per cent <br />
  15. 15. Water Shortages – Australia <br />Rice, cotton, citrus, dairy farms – collapsing<br />One million tonnes rice – down to 18,000 tonnes<br />Severe water restrictions in urban areas <br />Poisioning of wetlands <br />High salinity levels of water used for irrigation<br />
  16. 16. Water Shortages – Australia <br />“Adelaide may have the dubious distinction of being the first industrialized city to live in a constant state of water shortage” <br />(Nat Geo, 2009)<br />“It’s up to Australia to show the rest of the world what the new landscape will be – one that’s come to terms with limitations” <br />(Nat Geo, 2009) <br />
  17. 17. Water Usage – Virtual Water <br />Virtual Water – The amount of water embedded<br />in food or other products needed for its<br />production <br />Varies according to diet - high meat consumption vs vegetarian <br />Moderating our diets in the developed world could make much water available for other purposes<br /> <br /> <br />
  18. 18. What is the virtual water content of these products? <br />1 cup of coffee = 140 litres of water<br />1 kg of beef = 16,000 litres of water<br />1 kg of rice = 3,000 litres of water <br />
  19. 19. Water Usage<br />Australia, one of the driest countries, is among the top three exporters of virtual water on the planet. Rice, cotton, sugar – the most water-thirsty crops – account for 1/3 of water use. <br />Australia’s rivers are drying out so that Australia can export rice to China <br />
  20. 20. Water Usage – Water Footprint <br />Water footprint is a measure of the volume of water used by an individual, a school, or a community, both direct and indirect <br />At the National level the water footprint is domestic water use <br />+ virtual water imports<br />- virtual water exports <br />
  21. 21. Water Usage – Water Footprint <br />The water footprint of China is about 775 cubic meter per year per capita. Only about 3% of the Chinese water footprint falls outside China. <br />The USA water footprint is 2600 cubic meter per year per capita. <br />Japan with a footprint of 1100 cubic meter per year per capita, has about 60% of its total water footprint outside the borders of the country. <br />
  22. 22. The Water Cycle<br />
  23. 23. Water cycle in the Classroom <br />Some interactive tools: <br /><br /><br /><br />
  24. 24. Water cycle in the Classroom <br />Make your own water cycle poster from velcro/cardboard <br />Have pupils take turns to stick on the words for processes in the cycle <br />
  25. 25. How much water do we use? <br />The average Irish person uses about 148 litres of water per day <br />
  26. 26. How much water do we use? <br />
  27. 27. Water saving in school <br />How to start? Water Audit <br />Carry out a review checklist of water use/policy<br />Count/Map water outlets in school – number of sinks,<br /> toilets, any water-consuming appliances, outdoor taps<br />Measure and record amount of water uses by each outlet <br /> - Measure volume of toilet cisterns<br /> - Measure flow from taps in litres per min<br /> - Measure water volume per average use ie. handwashing<br /> - Record no. of toilet flushes per day <br /> - Record the no. of uses of sinks per day <br /> - Record any leaks/drips <br />
  28. 28. Water saving in school <br />Locate and read the school’s water meter <br />Irish meter readings are in cubic meters (x 1000 for litres) <br />Record the water usage on a daily/weekly basis and plot on a graph <br />Reading the meter when there is no water usage indicates a leak <br />
  29. 29. Some water saving tips for school <br />No Cost<br />Run a water conservation awareness campaign<br />Report leaks/drip to Local Authority <br />Don’t leave taps running <br />Take quick showers (5 minute shower campaign) <br />Monitor and record regularly and investigate any unexplained water usage <br />Review all activities where water is used to identify water saving opportunities ie Gardening,<br />cleaning ect… <br />Low Cost <br />Hippos/Water saving buttons for toilets<br />Repair leaking taps <br />Insert a water butt for watering plants <br />High Cost<br />Fit push taps <br />Fit spray taps <br />Replace inefficient older fittings with modern water efficient ones<br />Install push operated water timers on showers <br />
  30. 30. Water saving in school – case study<br />Kilnadeema N.S, Loughrea Co. Galway <br />Record water usage using meter - 40,000 litres per week <br />Underground leak discovered – meter active on the weekends <br />Leak detected and repaired <br />250 ml sand filled bottles placed in cisterns - ¼ litres saved per flush<br />60 litres of water per day/11,000 litres per year saved on toilet flushing <br />Awareness campaign – turn off taps, use sink stoppers <br />80% reduction in water use – 40,000 litres to 8,000 litres per week <br />
  31. 31. Water saving in school – case study <br />Aglish N.S, West Waterford <br />Rocks in the cisterns to reduce the volume of water used in each flush<br />Rocks saved 150 ml per flush<br />13.5 litres of water per day, 67.5 litres per week, 2,430 litres per year saved on toilet flushing <br />Every pupil turns taps off and keeps an eye on any leaks<br />Harvests rainwater for watering plants and flowers<br />Kettle filled up with the amount of water that will be used<br />Cartons, paintbrushes, etc. washed in a plugged sink to avoid constant running <br />
