The following Q&A addresses some frequent questions about water conservation, management practices, and the innovations helping to tackle the crisis. Let us learn more and discover how we can each play a role in protecting this precious resource… Frequently Asked Questions About the Water Crisis in India Q1: What is the recommended water consumption for household utilities? A: A simple wash basin in a household should consume 4 litres per minute. A sink in a toilet should have a 6 litres per minute capacity, and a shower should use 7 litres per minute. Q2: Which city in India has the highest water consumption? A: Pune has the highest water consumption in the country. The average is at 250 litres per capita per day, which is significantly higher than the Indian city average of 135 litres per capita per day. Q3: What is competitive extraction in the context of groundwater? A: Competitive extraction refers to the practice where if one person digs a borewell, another person will also dig a borewell, often deeper than the first. This leads to a situation where the more people dig borewells, the less water will be extracted, necessitating deeper and deeper wells. Q4: How do we value water? A: We often do not value water throughout the year and only realize its importance when we face a shortage, typically in the summer. Q5: Which country is leading in water management? A: Singapore is considered to be at the forefront of water management. They have implemented measures such as recycling and treating sewage water so it can be used as drinking water again. Q: Is it technically possible to drink treated sewage water? A: Yes, it is technically possible. The technology has reached a level where you can drink the flushed sewage that comes out of the plant. However, it will take time for people to psychologically accept this practice. Q: What is the current use of treated sewage water in Bengaluru? A: In Bengaluru, treated sewage water is used for lake recharge. The water is given to the lakes in the STPs, which are all the ponds in Bengaluru. From there, the groundwater is recharged. Q: How does the cost of desalination compare to sand water purification? A: Desalination costs around 40 to 60 rupees per kilolitre if you look at the Arabian Sea or the Bay of Bengal. In contrast, sand water purification can cost around 20 to 25 rupees per kilolitre. Q: What is the current situation with water scarcity in India? A: The availability of water has definitely decreased due to population growth and increased demand from other economic activities.
