Among the following which can help in conservation of water?
A. Recycling of water
B. Storing in lakes and tanks
C. Baulis
D. Tube-wells

Options

A. A, B and C
B. B, C and D
C. A, B and C
D. All of these

Answer

To solve the question of which options can help in the conservation of water, we will analyze each option provided:

1. **Recycling of water (Option A)**:
- Recycling of water involves treating used water so that it can be reused for various purposes, such as irrigation, industrial processes, or even drinking water after proper treatment. This process reduces the demand for fresh water and helps conserve it.
- **Conclusion**: This option helps in conserving water.

2. **Storing in lakes and tanks (Option B)**:
- Storing water in lakes and tanks allows for the collection and preservation of water for future use. This method is crucial during dry seasons or droughts, ensuring that water is available when needed.
- **Conclusion**: This option also helps in conserving water.

3. **Baulis (Option C)**:
- Baulis are traditional water storage systems that collect rainwater. They are designed to store water for domestic use and help in maintaining the water table. This method is particularly effective in areas with limited water resources.
- **Conclusion**: This option contributes to water conservation.

4. **Tube-wells (Option D)**:
- Tube-wells are used to extract groundwater. While they provide access to water, over-reliance on tube-wells can lead to depletion of groundwater resources. Therefore, while they can provide water, they do not necessarily help in conservation.
- **Conclusion**: This option does not effectively contribute to water conservation.

After analyzing all the options, we can conclude that options A, B, and C are effective in conserving water. However, option D (tube-wells) does not contribute to conservation.

**Final Answer**: The options that help in conservation of water are A (Recycling of water), B (Storing in lakes and tanks), and C (Baulis).
