The document discusses various methods for conserving water, including afforestation, irrigation, industrial use, domestic use, and rainwater harvesting. Afforestation helps replenish underground water levels by reducing surface runoff and improving water seepage into soil. Efficient irrigation methods like sprinkler and drip irrigation are recommended to avoid water depletion. Industries should recycle and reuse water for cleaning and cooling. At home, people should avoid wastage by closing taps properly and using greywater for gardening. Rainwater harvesting by collecting rain in tanks can also help conserve fresh water supplies.
