Water is the most important natural resource made available by mother earth to the humans. It is essential for existence of life and maintaining ecological balance. Life on earth without water cannot be imagined.
Although, earth constitutes 71% of water, only 2.5% of it is fresh water. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. In essence, only 0.007 percent of the planet’s water is available to fuel and feed its 7.3 billion people. The amount of fresh water that the earth holds has remained constant, but the human pollution consuming it has increased manifolds; subsequently, leading to water scarcity. Adequate measure must be taken towards optimal usage of water and methods like rain water harvesting must be implemented in order to ensure future availability of one of the nature’s most valuable resources.
Wherever they are, people need water to survive. Not only is the human body 60 percent water, the resource is also essential for animals, producing food, clothing, and computers, moving our waste stream, and keeping us and the environment healthy. Unfortunately, humans have proved to be inefficient water users.
According to the United Nations, water use has grown at more than twice the rate of population increase in the last century. By 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world’s population living in water-stressed regions as a result of use, growth, and climate change. The challenge we now face as we head into the future is how to effectively conserve, manage, and distribute the water we have.
Cape Town’s Water Crisis
Cape Town’s water supply is running dry and might reach the much-feared “Day Zero” in 2019 (officials had originally estimated July 2018). As apocalyptic as it may sound, South African officials have confirmed the gravity of the situation, stating that the city will almost inevitably lose piped water to homes and businesses at some point in 2019.
What can we do to avoid such crisis before hitting our locations we live in. Please follow some of the water saving tips mentioned below.
Tip 1: Use Water Saving Nozzle
Water saving nozzles saves up to 80% water on taps with no sacrifice in water pressure and rinse-ability of user. The technology is such that air is mixed with the water to create a steady stream of water, and a barely noticeable change in water pressure. Also known as water saving aerator, water saver, water tap filter, shower aerator, spray aerator. You could buy the nozzle from Amazon. To get a better understanding of how such nozzles will save water, please watch the below video.
Tip 2: Recycle A/C Water
As warm air is cooled by an air conditioning system, humidity in the air forms condensation. Typically, this water is drained into a sump pump, a floor drain or outside. In hot, humid weather, an air conditioner may produce five to twenty liters of water per day. This water can be easily captured in a bucket or barrel or redirected to a nearby garden. Condensate capture systems can help collect and redistribute the water where it is needed.
Water from air conditioner condensation can be used to water indoor and outdoor plants. The condensate is pulled out of the outside air, and so it does not contain chlorine or other additives that may be present in normal drinking water. The water can be used to fill a watering can, redirected to a rainwater collection system or drained directly to a nearby garden to water outdoor plants directly.
Outdoor Cleaning / Toilet Flushing
Air conditioner condensate does not contain soaps, chlorine or other chemicals that may be found in fresh water or other gray-water sources. As a fairly clean source of water, it can be used to wash and rinse windows, outdoor furniture and vehicles, flushing toilets.
We are using the A/C water for flushing toilet due to water scarcity in our office location.
Encore a company from United Kingdom has created a environmentally friendly toilet cistern. It uses the condensate from air conditioning units to flush toilets.
Tip 3: Recycle Wastewater from RO system
Reverse Osmosis Filter rejects 75% of water and only 25% of the water gets extracted as drinking Water. For eg: If you need a one liter pure drinking water, the system rejects 3 to 4 liter of water as hard water. Therefore, Household Reverse Osmosis rejects the water through house drains and in a day discharge between 20 and 90 gallons of waste-water.
The waste water from Reverse Osmosis Filter may not be pure for drinking purpose, but can be used for washing clothes, cleaning floors and watering plants or washing car etc. For re-using the waste water from Reverse Osmosis Filter, instead of letting the water through house drains, you can collect the rejected water in a container or storage tank and the water can be reused for non-drinking purpose like washing clothes, cleaning floors and watering plants or washing car etc.
Tip 4: Stop Water Overflow
Almost all homes and commercial premises in India and overhead tanks for water storage. And all of us have seen ours or our neighbours’ water tank overflowing at some point in time. We can easily stop the overflow from our water tanks and save hundreds of liters of water daily by simply using one of the below solutions:
Install a Float Valve
A float valve is a very simple, inexpensive but highly effective equipment for stopping the tank overflow. It automatically stops the incoming flow of water in the tank when the water in the tank reaches the maximum level. This solution is best suited for water tanks which are filled using normal incoming water pressure. Always remember, you should never install a standard float valve if you are using a water motor/pump to fill the water tank.
Water Tank Overflow Alarm
A standard float valve is a piece of great equipment for stopping the tank overflow if you are not using a water pump for filling the water tank. But what about the people who are using a water pump? Water Tank Overflow Alarm is a small electronic device that alerts you every time water overflows from your tank. It does not stop the flow of water, it simply raises an alarm so you can shut off the water pump. This simple device not only saves water but also saves electricity because your water pump is not left running even after your water tank is full.
Automatic Water Level Controller
As the name suggests, Automatic Water Level Controller is an electronic device which controls or manages the water level in your water tank. It consists of an electronic controller and water level sensors. The electronic controller is connected to the electric supply, water motor/pump, and the sensors. This device automatically switches on/off your water motor/pump when the water level in the tank reaches the minimum/maximum level.
Other Saving Tips
Fix your Leaks – Known or unknown leaks in taps, pipes, and toilets can result in up to 11,000 Liters of water being wasted. You should always check all your bath fittings for any leakage and get the leaks repaired as soon as possible. This will not only save wastage of water but will also avoid any damage to your walls and fittings.
Turn Off the Tap While Brushing your Teeth or Shaving – An average tap or faucet throws approximately 10 liters of water every minute. So don’t leave the tap open while brushing or shaving. Turn off the faucet after you wet your brush, and turn it on when it’s time to rinse.
Turn Off the Tap While Washing your Hands – Do not leave the tap running while you’re scrubbing your hands. Wet your hands and turn off the tap, turn on the tap when you need to rinse.
