On March 22, World Water Day is celebrated across the globe. This year’s theme is “Water and Gender Equality”, and the slogan is “Where water flows, equality grows.” Today, water use and conservation have become strategically important priorities for many countries around the world. This time, we would like to tell you about the methods different countries use to ensure water conservation and combat water theft. In Singapore, the “Four Taps” strategy is applied to meet the population’s water needs:
- importing water,
- collecting rainwater,
- desalinating seawater,
- and recycling domestic wastewater using advanced technology.
In addition, water tariffs are progressive: the more you use, the higher the rate you pay. Fines are also imposed for water wastage. Israel is considered a global leader in water conservation, especially in agriculture. More than 80% of irrigated areas use drip irrigation, which allows saving up to 50% of water. Within the framework of a national program, about 86% of wastewater is treated and reused in agriculture. Water theft is considered a serious crime, with strict penalties including heavy fines and imprisonment. Spain, which often faces drought-related challenges, widely uses treated wastewater for irrigating parks and green areas. It is prohibited to wash cars or fill private swimming pools with drinking water.
Fines for serious violations of water use regulations can reach up to 3,000 euros, while breaking restrictions such as washing cars, watering gardens, or filling pools may result in fines of up to 50 euros. In California, USA, seasonal pricing is applied, meaning that water prices increase significantly during the summer months to limit consumption. Water reuse is also implemented at the state level. Water theft here is also considered a serious offense, regulated by both state and federal laws, with penalties including substantial fines and, in major cases, imprisonment. Japan stands out for its technological and legislative approaches to water conservation. The use of “Johkasou” technology allows treated wastewater to be reused for garden irrigation. In Tokyo alone, water pricing is divided into 9 tiers with significant differences between them. In the city of Fukuoka, a special law requires large buildings to install rainwater collection systems.
