The average Indian urban household uses 135 litres of water per person per day. With groundwater levels declining across the country and water bills rising, reducing consumption at home is both an environmental responsibility and a financial opportunity. Here are 20 practical steps you can take starting today.
Fix Leaks First — They Waste More Than You Think
1. Fix dripping taps: A tap dripping once per second wastes 11,000 litres per year — enough for a family of 4 for a month. Replacing a tap washer costs Rs 20–50 and takes 20 minutes. 2. Check toilet flapper valves: A silent toilet leak (water continuously running from tank to bowl) can waste 200–400 litres per day without any visible drip. Add food colouring to the tank — if colour appears in the bowl without flushing, you have a leak. 3. Inspect pipes annually: Pipe connections under sinks and behind walls can develop slow leaks. An annual inspection prevents both water waste and damage.
In the Kitchen
4. Wash vegetables in a bowl, not under running water: Running water for vegetable washing uses 10–15 litres per minute. A bowl uses just 3–4 litres. 5. Reuse RO reject water: Collect the reject water from your RO purifier (typically 1–2 litres per litre purified) in a bucket. Use it for mopping, toilet flushing, or watering plants. This alone can recover 15–30 litres daily. 6. Use a dishwasher efficiently: Modern dishwashers use 12–15 litres per cycle. Hand-washing the same load uses 40–60 litres. Run full loads only. 7. Defrost food in the refrigerator, not under running water.
In the Bathroom
8. Take shorter showers: Reducing shower time from 10 to 5 minutes saves 50–75 litres daily. A 5-minute shower uses around 60 litres versus 120+ for a 10-minute shower. 9. Install low-flow shower heads: Low-flow shower heads (aerators) reduce flow to 8–10 litres per minute from a standard 15–20 LPM without noticeable difference in shower quality. Cost: Rs 500–2,000. Annual saving: 15,000–25,000 litres per person. 10. Turn off tap while brushing teeth: A running tap during tooth brushing wastes 6 litres per minute — 12 litres twice a day. 11. Install dual-flush toilets: Half-flush (3L) vs full-flush (6L) saves half the water used for liquid waste.
In the Garden and Outdoor Areas
12. Water plants in the morning or evening: Daytime watering loses 30–40% to evaporation before the water reaches roots. 13. Use drip irrigation: Drip systems deliver water directly to roots with 90% efficiency versus 50–60% for sprinklers. 14. Collect rainwater: A simple rainwater collection barrel under a downpipe can collect 500–1,000 litres in a single monsoon shower — free water for gardening. 15. Choose drought-resistant plants for balcony gardens and compound planting.
Laundry and Appliances
16. Run washing machines with full loads: A 7kg machine uses the same water whether it is 3kg or 7kg full. Washing 4 full loads uses the same water as 8 half-loads. 17. Use the eco-mode on appliances: Eco-mode on washing machines and dishwashers reduces both water and electricity use by 20–40%. 18. Buy water-efficient appliances: When replacing appliances, check the water efficiency rating. 5-star rated washing machines use 30–40% less water than 1-star models.
Smart Water Management
19. Install water metres on tanks: An overhead tank metre shows exactly how much water you use daily and helps identify sudden leaks. 20. Consider a high-efficiency RO purifier: Upgrading from an older RO with a 25% recovery ratio to an Alkin model with 60% recovery saves hundreds of litres monthly from purifier reject waste alone.
