Toilets as we know today have existed for about a century only. Earlier homes didn’t have the flushing toilet and even taking a bath was considered quite a luxury. The flush toilet is the most popular toilet that is used the world over and were known as water closets in the 19th century. Though the concept has been in use for a long period. Around 4000 years ago, in the Indus valley Civilization, toilets and sewers were an integral part to the city planning. The water flushing toilets were usually used by the affluent and these were linked to the drains that were also covered.
Remnants of water flushing toilets were also found at Skara Brae in Oakney, Scotland around 3100 BC – 2500 BC. The Pharaohs and ancient Persia also had toilets around the 18th century BC. While toilets during the roman times were a part of the public bath houses.
In the US, it was estimated that 90 liters of water were used by individuals in the flushing toilets everyday. Now newer designs are being implemented and researched that will reduce the water consumption and wastage. In many homes and offices, dual flush toilets are in use that is meant for reducing the wastage of water. The dual system uses less water for flushing smaller loads of wastage.
