Flushing the toilet is a major issue when it comes to water conservation, which in fact is connected to the preservation of the environment.

Water has been one of the major environment issues all over the world hence there have been many campaigns on how to conserve water every single day.

Water is an important commodity. It can be considered as people’s liquid gold – for without water, people will cease to exist.

It is said that people can live without food for at least 1 to 2 months, sleep for 11 days at the most, but water is a different story. People cannot survive without water for more than 3 to 7 days.

That is the reason why it is important for people to find ways to conserve water because it is an important necessity.

Water is truly vital, especially in a household. Bathroom hygiene needs a lot of water, especially when you are taking a shower, peeing and defecating. In the traditional way of flushing, a toilet uses a lot of water.

It varies depending on what type of toilet unit you are using. According to reports, the average water usage in bathrooms alone in 1992 was around 3.5 to 5 gallons per flush – this is using the regular type of toilet units. When added up, a significant amount of water is “flushed” down the drain every day.

Due to the large amount of water being used just to flush the toilet, in the same year, the US government said that new toilets must not exceed more than 1.6 gallons of water to flush. Hence, many households started to change their units just to help in the conservation of water.

What is the Dual Flush Toilet System?

Over the years, there have been a lot of people who found ways to help save water. Some save water by putting bricks on their water cistern to reduce the amount of water being flushed. While it had been effective, it is not consistent and needs a lot of work.

Bruce Thompson, of Caroma Industries in 1980, created the first 2-button flushing system. This is the best way to choose the volume of water on each flush – a full flush for solid waste and half flush for liquid waste.

This dual flush toilet system has the benefit of using less water even if you are using the full flush. Most of these toilet systems use less water which is seen as one great solution to help conserve water.

Hence installing a dual flush toilet is a great way to help with water conservation. According to the Environmental Protection Agency (EPA), if all Americans would replace their old style toilets, we can save around 2 billion gallons of water every day across the nation.

You don’t have to change your lifestyle greatly to help the environment, but replacing your old flushing systems with devices that have efficient features will significantly help not only the environment, but your money as well.
