Do low-flow showers actually save water?

A conventional showerhead with a pressure of 1.5bar and 7 minutes running time can consume 112 litres of water! Over the same period and supply conditions a water and energy saving showerhead will consume 49 litres; a water saving of 56.25%. This then saves one money on Water Bills and on Energy Bills to heat the water, because you are heating less water!

Low-flow showerheads maintain pressure and use less water. There are two types of low-flow shower heads:

Aerating shower heads force air into the water stream, maintaining an even and steady flow. The extra air may reduce the temperature slightly.

Smaller spray nozzle shower heads do not mix the water flow with air. As a result, the water pressure may feel like it is pulsing, creating a massaging effect. They also keep water hotter than aerating shower heads because the water stream is not cooled by aeration.

You could save 2,900 gallons per year by installing WaterSense labeled showerheads. Since these water savings will reduce demands on water heaters, they will also save energy. In fact, the average family could save more than 370 kilowatt hours of electricity annually – that’s enough to power a house for 13 days!

I find that the amount of water that comes out of my low-flow shower head is adequate to get me clean quickly. I like that it has some velocity to it. I don't see any time difference. My showers take about 10 minutes either way.

Your premise is incorrect. You do not have to take longer showers in order to get clean. As a matter of fact, you will probably not notice any difference if you install one (correctly).

Who cares? Just drill out the orifice. Who needs the government in their shower?

Its your duty to save the water for future ..thats helps.
