Conserving water | Products

Contribution by improvement in water-saving features and the widespread use of water-saving products

The TOTO Group is promoting efforts to reduce water consumption during product use and thus conserve water resources in the region by expanding the sales of water-saving products on a global scale. We defined the Avoided Emissions of water during product use as the amount of reduction in water use compared to the case where we have been spreading the use of the then product range in 2005. we set specific targets and manage their progress.

The amount of Avoided Emissions of water during product use will expand as more customers use products with high water-saving performance,We are aiming to achieve the target of Avoided Emissions of water during product use by improving water-saving performance and further promoting the use of water-saving products.

The Group reduced 1 billion m3* in fiscal 2023 and is targeting a reduction of 1.14 billion m3 in fiscal 2026 under WILL 2030 STAGE 2.

* In case the same calculation conditions are used as in WILL 2030 STAGE 2 (approximate value)

Water-saving Initiatives for Toilets

Advancing the water efficiency of toilets

The TOTO Group has achieved a further enhancement of the water-saving performance of toilets, which use more water than any other plumbing equipment in the home for maximized contribution to the environment by saving water.

In Japan, TOTO released a new toilet that uses 13 liters per each large flush in 1976, achieving water savings of 35% compared to earlier toilets. Since then, we have continued to increase water-saving efficiency by Tornado Cleansing, developed for the first time anywhere in the world in 2002 and other products, subsequently releasing a toilet using 4.8 liters per flush in 2009, and a super water-saving toilet using 3.8 liters per flush in 2012.

Overseas too, we similarly released a 4.8-liter toilet in the United States and China in 2006, even before its release in Japan.

Since then, we have released a 3.8-liter water-saving toilet intended for the US and Chinese markets, as well as our 3.8-liter NEOREST toilets featuring Washlet equipped with a toilet bowl cleaning function “eWater+” and our new photocatalytic technology “Actilight” intended for markets in the Americas, China, Asia/Oceania and Europe.

Developing and expanding the use of water-saving toilets

In countries around the world, strict regulations on the volume of water used per flush have been instituted as a measure to combat water shortage problems.

Since even before these regulations, the TOTO Group has been committed to making positive contributions to the environment through its business activities, by making our 4.8-liter toilets the global standard, and by globally promoting the use of water-saving toilets that use less than 4.8 liters per flush.
