  • We agreed as a group that water is essential for our planet to survive, and that we need to raise awareness regarding the imminent shortages of water.
  • Poor water quality can increase the risk of such diarrhoeal diseases as cholera, typhoid fever and dysentery, and other water-borne infections. Water scarcity can lead to diseases such as trachoma (an eye infection that can lead to blindness), plague and typhus

  • Sanitation in Brazil
  • Sanitation in Brazil Main Problem Only 57% of the population has access to a publicsanitation system
  • Sanitation in Brazil Main Problem Only 57% of the population has access to a publicsanitation system Really difficult to put a good sanitation system intopoorer areas like slums

  • Overall To notice water reduction should significantlybe considered in our institution To take the initiatives in order to use the leastamount of water possible We’re doing the best we can do.
  • EcoÁgua ProjectGraded School’s Global Issues Network and Draco Soluções
  • What? Implementation of: Small, economizing faucets on all applicable sinks ofthe school Toilet valves that limit the amount of water per flushby: Limiting amount of action time Amount of water released Effectiveness remains the same
  • When? Part of the project took place during Brazil’swinter break The project takes time, thus having studentsaway from campus is ideal
  • Why? Initial mindset: We want to help the planet by saving water Economically: Saves a lot of money Saves a lot of water Graded will be viewed as an even moreresponsible and caring institution
  • Draco Soluções Leader in the market Focuses on reducing water consumption Usually make their products for places with a highflux of people Our case: ~1,500 students and faculty Benefits: Two-year warranty 24 hour maintenance service
  • Key Points Sabesp’s data: Around 1,800 cubic meters of water per month Includes kitchen, garden, toilets, sinks, inter alia(General consumption) Each cubic meter costs $ 5.80 = $ 10,420 per month All following values are rounded down savings can exceed estimates
  • Sinks Sinks are responsible for 10%-15% of water consumption Faucets save 70% water per use 7% to 13% of general consumption Approximately 120 cubic meters per month – 1440 cubicmeters per year Around $ 690 per month Around $ 7840 per year Total investment: 186 faucets for $14.00 = $ 2605.00
  • Sink FaucetsBefore After
  • Sink Implementation √ All sinks in school now have the faucets  Because August-September suffered from adrought, more water than usual needed to beused in campus Hence, we still do not know how much waterhas been saved
  • Toilets Toilets are responsible for 30% to 40% of water consumption Valves save 30% water per flush 9% to 16% of general consumption Approximately 160 cubic meters per month, 1,920 cubicmeters per year Close to $ 881.40 per month, $ 10,283.00 per year Total investment: 132 valves for $ 78.30 = $ 10,335.60
  • Overall Savings Around 22% savings of general consumption Approximately 280 cubic meters per month 3360 cubic meters per year This equals 3,360,000 Liters An average Olympic pool has a volume of 2.5 millionliters Around 1.5 Olympic pools’ volume saved Roughly $ 1570 per month Roughly $ 18,705 per year

  • Overall Investment Total investment of $ 13,010.00 Break-even occurs after 8 months $ 12,540 saved in the beginning of 8th month 1st year savings= $ 5700 2nd year savings(accumulated)= ~$ 24,400 Again, savings may be much higher asestimates because the lowest percentages wereused

  • Towel Dispensers Project
  • What?• Textile Company in Europe/USA that makestowel dispensers• Cycle to re-use the paper towelsFill theDispenserWash TheTowelsRe-use thesame towels
  • Usage• Pull down on the 4Ply towel• Known as the “clean zone”• No need to touch anylevers, knobs, or buttons• After use• The soiled portion of the paper is automaticallywounded up into a separate, special compartment• As soon as the clean roll finishes, it enters there-use cycle
  • The Present Situation• Common Paper Towels Currently Installed• Ineffective• Require two sheets (many people use more) to drytheir hands• Generates waste• Paper is thrown away after being used once• No recycling method for them
  • The Present Situation• Common Paper Towels Currently Installed• Ineffective• Require two sheets (many people use more) to drytheir hands• Generates waste• Paper is thrown away after being used once• No recycling method for them
  • The Plan• Gain access to these dispensers• Purchase 100 dispensers for 80 bathrooms oncampus• From Either:• Lindstrom (Finland)• Darman Manufacturing (USA)• Find a company that could clean the towelsfor us or wash them ourselves on campus
  • Why?• Saves water• These towels can be re-used up to 200 times, instead ofbeing used once• Money savings• Not having to buy massive amounts of paper per year• Tremendous amount of labor to collect the trash won’t beneeded• Hygienic virtues• No knobs/buttons to touch = less germs = health
  • Why Water?• 38-50 gallons of water are needed to make a pack of papertowels• Graded currently purchases:• About 2,150 packs of paper towels per year• Around R$ 140,000.00 ($ 69,000.00) are used to purchase the papertowels annually• Savings• 107,500 gallons of water per year = 430,000 sheets of paper (200 perpack) per year• 226 rolls need to be purchased once• A total use of ~39,000 gallonsyYear 1Breakevenx
  • Why Water?•• Washing Machines use around 10-24 gallons of water per use• In relation to current water expenditures with paper towels• We would have to use the machines about 4,008 times to equal the107,500 gallons wasted per year• Means the machine has to be used 11 times per day• Each roll of paper from this dispenser can provide 1900 hands dried beforebeing washed• If, on average, around 250 people access each bathroom on campus:• Washing would only occur every 8 days• 40080 gallons of water would be consumed in the year of the purchase• 1080 gallons would be consumed every following year until new rolls arepurchased
  • Why It Is Not A Formal Proposal, Yet• A few things to think about:• “What if water is saved but more energy is wasted?”• How much energy is used per washing machine?• The values fluctuate depending on the type of machine• Therefore, there’s no standard amount of energy that isusedVs.
  • Not Possible Implementations
  • Not Possible Implementations
  • Sprinkler Control on Grass Fields Why? – sprinklers could be used excessively without reason Procedure: Contact maintenance and ask if there was a specific schedule forthe sprinklers If so, what happens during rainy days? Data collection: Sprinkler has a fixed schedule that disregards rainy days We were told that the schedule has been carefully planned outin a way that does not waste water
  • The Kitchen Challenge: How to reduce amount of water while maintaining effectiveness in cleaning andhygiene What if water is used unnecessarily when the kitchen cleans thousands of platesper day? Procedure: Take a tour in the cafeteria Count amount of faucets Question about the method of cleaning the dishes Data Collection: Water is only used to clean the floors Dishwasher does not use too much steam, it shares the workload with steamand heat
  • Proposals Reduce the amount of sinks and faucets in the kitchen Implement faucets that use more pressure than water Exchange the dishwasher for one that only uses steam, andno water
