How to take rainwater from roof to storage system?

To take water pipes or drains to the storage/harvesting system rainwater from the rooftop should be carried down and water pipes should be UV resistant of the required capacity. Through gutters and down take the pipe water from sloping roofs could be caught and the mouth of each drain should have wire mesh to restrict floating material at terraces.

Are rainwater harvesting systems bad for the environment?

Rainwater harvesting systems have few negative environmental impacts compared to large centralized water supply projects. Water collection and storage capacity can be increased as needed to meet increased demand for water.

What is the catchment of rainwater harvesting system?

The surface that receives rainfall directly is the catchment of rainwater harvesting system. It may be terrace, courtyard, or paved or unpaved open ground. The terrace may be flat RCC/stone roof or sloping roof. Therefore the catchment is the area, which actually contributes rainwater to the harvesting system.
