Rainwater Harvesting

Rainwater harvesting is the collection and storage of rainwater from roof surfaces for later use, typically in non-potable applications.

Why Harvest Rainwater?


Harvesting rainwater is a good water conservation practice. This source of water can be used to irrigate landscape beds, butterfly gardens, rain gardens, and container plants, as well as to create wildlife features such as birdbaths or butterfly puddling areas.

Management of Stormwater

Rainwater harvesting helps protect clean water by decreasing the amount of stormwater runoff which leaves a site. As stormwater moves across the landscape, it transports pollutants, such as fertilizers, pet waste, sediment, and litter, to nearby waterways. By reducing runoff we reduce the amount of pollution reaching local water bodies.

Flooding & Erosion issues

Rainwater harvesting can also be used to manage flooding and erosion around the foundation of a building. In problem areas, an appropriately sited rain barrel or cistern can help manage water to both slow the flow and transport water away from the building.
