Water, the universal solvent of life, is becoming scarce to some places around the globe, as it can no longer meet the demands of daily usage. There were lots of communities do not have access to clean water. As the population grows, the demands for agricultural products, and power generation increases. Both agriculture and power generation needs water. Some places are already experiencing drought because of uncontrolled expansion of agricultural farms that produce water-hungry crops like avocados. These crops yield more if you feed them with water well. The distribution of water to residencial areas has been minimized. In power generation, most power plants are drive by steam turbines. You cannot create steam without water. Nuclear power plants, coal power plants, geothermal power plants and diesel power plants that use different fuel to generate power, still need water to move steam turbines to drive generators. Sea water is now being filtered and desalinated with the use of technology to counter water scarcity. However, the process costs a lot of money for power requirements, treatments, and maintenance.
You should start conserving water now. Start it at home. One way of conserving water is to install foot pedal controlled valves to your showers or faucets. How it works? We use to wash our body or our hands with soap and wash the dishes with dishwashers, right? Most of us leave the faucets open and let water flows while we are busy rubbing our hands with soap or while we are applying detergent to dishes. It may take seconds to minutes before we are going to rinse them again with water. Some may close the valve but others don't. It is also uncomfortable to close the faucet while you are rubbing your face with soap or facial products while your eyes are closed.
With pedal controlled valve installed, your foot would be your third hand. While your two hands are busy, the third hand will control the water flow. You can save water as it stops the water from flowing out of your faucet while you are busy with soaps. Pedal valves are widely used in drinking water fountains. Some kitchen sinks, aside from pedals, come with spray heads or hand triggered sprinklers.
Pedal valve has different types to choose from, in terms of mechanism. The oldest one is the mechanical pedal valve that uses springs, flappers, or rubber balls. There is also electronic pedal valve that uses low voltage circuit to drive an electronic or solenoid valve. There is also a pneumatic type that uses oil that moves a sealed mechanism inside the pedal main casing. Pedals can be made of brass, metal alloys, stainless steel, and plastic. They are widely available on hardware, home improvement stores and online shops like Amazon or Ebay. Below is a link to a good quality pedal controlled valve available at Amazon.
