It provides recommendations such as opening the water tap little when washing hands, taking showers instead of baths, using a watering can instead of a hose to water plants, and sharing concerns about water waste with classmates by posting signs. Other schools recommend closing the water when brushing teeth, washing dishes with minimum water, washing cars with only a pot of water, taking short showers, and watering plants at specific times to reduce evaporation.
