#ConserveWaterMonth Dual Flush And Other Ways To Save Water


An average flush uses around 13 litres of water per use. Calculate the basic and it means that every person uses around 70 litres of water for flushing every day. This is a significant chunk (around 25 percent) of daily water use in a household. If you have the older version of the flush, it means you’re using more water each time. In fact, some of the very old designs, probably the majority in our country, can use around 25-30 litres per flush. So how can you still flush in a way that helps you save water? Read on.

1. Use The Dual Flush Option

Dual flush systems offer two options – a light flush and a normal flush. Light flush, usually activated by pressing the smaller button, lets you flush with only half the water available. This is useful for liquid waste when you don’t need to use the entire flush water. The other button works normally and is used for solid waste.

2. If Possible, Switch To Toilets With Low Water Usage Designs

Apart from dual flushing options, modern water closets have ultra low water consumption designs. Some consume only 3 litres for half flush and 4.5 litres for a full flush. This would reduce water consumption by a huge margin. While we still don’t have a rating system for flushes in India, you can go through the company catalogue to understand how much water a specific model will use.

Are Dual Flushes Expensive?

Most dual flush systems come in the full ceramic body one or two piece water closets. They are more expensive than ordinary systems and all major brands such as Parryware, Hindware, Cera, Kohler, Roca offer the same. Their range starts at around INR 6000. However, if it does not suit your budget, you can use the older plastic design dual flush available for around INR 1400 from Parryware and a few other brands too.

Other Tips To Save Water

  1. Using fresh treated water for flushing is essentially a waste, so try to use gray water (waste water from washing clothes, bath, etc) for flushing. To do so, you will have to rewire your pipes and a plumber will be able to help.
  2. Alternatively, you can try and source a Japanese wash basin that fits over the cistern. It directly uses the waste water that is wasted out after washing hands.
  3. Do not use the water closet as a garbage bin to flush tissues and other waste.
  4. Use a hand held toilet spray or inbuilt bidet sprays instead of tissue paper to save trees.
  5. You can also insert a plastic bottle inside your cistern and reduce its water consumption by 1-2 litres.
