Why rainwater harvesting is a best method for recharging underground water?

It minimizes the impacts of flooding by funneling the off water into large tanks for recycling and helps reduce the load placed upon drainage systems. No land is wasted for storage purpose and no population displacement is implicated therefore, groundwater is not directly exposed to evaporation and pollution.

Which method of rainwater harvesting is more effective?

a) Storage of Direct Use It is advisable that each tank should have excess water over flow system. Excess water could be diverted to recharge system. Water from storage tank can be used for secondary purposes such as washing and gardening etc. This is the most cost effective way of rainwater harvesting.

• Conserves water.
• A source of water for landscape irrigation.
• It is a simple method and easy to practice.
• It reduces soil erosion and pollution of water bodies due to fertilizers and pesticides.

How does rainwater harvesting help in storage of water?

Why is rainwater harvesting bad?

These pollutants then may be transported in the storm drain system and, eventually, to receiving waters. If the water is harvested for use, several of these materials release pollutants for at least one year after installation at concentrations high enough to be of concern for plant toxicity.

What are the benefits of storing rainwater?

The benefits of rainwater harvesting system are listed below.

• Less cost.
• Helps in reducing the water bill.
• Decreases the demand for water.
• Reduces the need for imported water.
• Promotes both water and energy conservation.
• Improves the quality and quantity of groundwater.
