Drought and Water Scarcity
Drought is the slowest emergency. It builds over months, and by the time restrictions arrive the reservoirs are already low. It also brings other risks with it: wildfires, heatwaves, higher food prices and, in some regions, power shortages. Households cannot make it rain, but they can cut water use sharply and be ready for restrictions.
1. Before: make your home water-efficient
- Fix dripping taps and running toilets. Small leaks waste large amounts over a year.
- Fit water-saving shower heads and tap aerators.
- Choose plants that need little water, and mulch garden beds.
- Collect rainwater for the garden where it is allowed.
- Store drinking water for at least 7 days. See Water outages and the kit calculator.
2. During: when water is short
- Follow the restrictions from your municipality or water company. They are set so that drinking water lasts.
Indoors
- Take short showers instead of baths.
- Turn off the tap while brushing teeth, shaving and soaping.
- Run the washing machine and dishwasher only when full.
- Reuse water: the water you rinse vegetables in can go to plants.
Outdoors
- Do not water lawns. Grass recovers.
- Water plants early in the morning or late in the evening.
- Do not wash cars or fill pools during restrictions.
Related risks
- Fire risk is high. Respect fire bans, and never throw away cigarettes or use a grill on dry ground. See Fires.
- Drought often comes with heat. See Heat and cold waves.
- If you have a private well, check its level and water quality.
3. After
- Keep the habits that worked. The next drought starts with full reservoirs.
- Heavy rain on dry ground runs off fast. Be alert to flash floods. See Floods.
- Refill your stored water.
Quick checklist
- Leaks fixed
- Water-saving shower head and taps
- Drinking water stored for 7 days
- Local restrictions and fire bans known
- Garden adapted to dry periods
