Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favorite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water.

According to the Department of Health, to keep ourselves healthywe should drink about 1.2 litres of fluid daily. Yet, less than 2.5% of the world’s water supply is safe and drinkable. Moreover,less than half of this is readily accessible. Already 900 million people lack access to safe drinking water, with 5,000 childrens’ deaths everyday globally. By 2025, the UN estimates that approximately 67% of the world’s population will be water stressed, pushing water scarcity as a top global risk.

In order to meet the projected growth in water demands sustainably, it is critical to make huge improvements in water productivity and efficiency. However, in the United States alone, an average of 400 liters of fresh water per day are consumed per person. That’s more than 87 gallons daily per U.S. citizen. By contrast, in other western countries, the consumption level reaches only 150 liters per person.

Here at Ocean Thermal Energy Corp, we are extremely passionate about empowering communities worldwide with technologies that can securefresh drinking water and clean energy. However, we also appreciate that by taking the smallest steps and becoming conscious about water efficiency, we can play a growing role in helping to preserve future water supplies.

With World Water Week commencing on September the 6th, we have produced a “Top 10 Simplest ways to Save Water” – giving you hints on easily achievable ways that we all can reduce our water use. They really are simple!

  1. Taking a shower instead of a bath will save up to 50% of water use.
  2. Turning the tap off while brushing your teeth or shaving will save up to 10 liters of water per minute.
  3. Reducing your food waste also reduces your water waste. Food production requires heavy water use. Throwing away one tomato (purchased from a supermarket) is equivalent to throwing away 13 liters of water, while an apple is 60.
  4. Capturing tap water by putting a bucket in the shower or sink while waiting for it to get up to temperature can save up to 300 gallons per month, allowing it to be used for watering your garden or washing the car.
  5. Boiling water with kettles accounts for a third of all electricity used in cooking. Being cautious with the amount of water you are boiling, reduces both water and energy consumption.
  6. Planting drought-tolerant plants that are used to drier conditions over attractive, bright and water thirsty species will help flowerbeds and pots retain water, thus reducing the amount of water required to keep them healthy.
  7. Watering your plants in the evening provides more efficient water absorption, compared to watering plants in the morning where a vast majority of it becomes evaporated and unused by your plants.
  8. Using a bucket of water to wash your car rather than a hose will save 150 gallons of water per wash. For the size of a family car, that’s up to 1,200 gallons per month you can save.
  9. Shortening your time spent in the shower by just two minutes will reduce water consumption by 700 gallons per month. If a family of four achieved this, 2,800 gallons of water could be saved each month, totaling to 33,600 gallons of water per year.
  10. Repairing those dripping taps with the purchase of a cheap washer can prevent the waste of 3,000 gallons of water per year.

So there you have it. Ten quick and achievable ways of reducing water consumption at home. Have a new idea? Share how you are reducing water consumption for World Water Week by sending us a tweet at @OTEcorporation.
