Replacing is not a way of conserving water.

Conserving water means saving water so that we don’t run out of it in future. Water conservation policies involve ways in which e can meet the current and future human demand of water.

By replacing water we won’t be able to save water in anyway. We can conserve water by reducing the use, for example, closing the tap when brushing teeth or using bucket instead of shower.

We can conserve water by reusing. For example, water from the RO water purifiers can be collected and reused for washing the floor.

We can also recycle water. For example, water harvesting. Water from the rain can be collected and used for various purposes.
