There are a variety of ways to collect or harvest rainwater. These methods come with their own benefits and means of utilization, as well as costs. Permeable pavements and rain gardens are considered passive types of rainwater harvesting. This essentially means that the water collected is distributed immediately using the landscape and ground as storage. Rainwater harvesting systems are an active type of rain collection, which means that some or all of the rainwater collected is stored for later utilization.
