Active vs. Passive Water Harvesting

On both residential and commercial scales, water can be harvested either passively, actively, or through a combination of both. These two methods are commonly utilized, and each way provides it’s own benefits.

Passive Water HarvestingPassive Water Harvesting
The passive form of water collection is considered the most “green” option as there’s no mechanical methods of collecting involved. Collecting water passively means you’ve simply set up an area that can contain water until the water can naturally be absorbed by the land.

Passive systems such as vegetated swales, wetland ponds, dry creek beds, and green roofs are generally inexpensive and are fairly simple to design and build.

Active Water Harvesting
It’s becoming more common to combine active and passive water harvesting for an increased “green” effect. Active harvesting means equipment is used to collect, filter, store and deliver harvested water. While active harvesting systems are more expensive, it comes with the added benefit of further reducing the funds needed for municipal water and water treatment.
