Engledow Tips for Landscape Sustainability: Rainwater Harvesting

Most people don’t have any idea about how much storm water is generated on their own property.

An average 1 inch of rainfall on a 2,000 SF roof generates 1,250 gallons of water. Indianapolis receives on average about 42 inches of rainfall per year. That could amount to more than 50,000 gallons of water that is over-burdening our storm water sewer systems and polluting our waterways. Engledow offers up a couple of ways to help reduce the amount of excess storm water run-off in our community.

Rainwater Harvesting: Rainwater harvesting is all about capturing and reusing one of earth’s most precious resources and there are several methods of doing this:

  • Rain Barrels: This is the most basic method, where a 50-75 gallon barrel is connected to your gutter downspouts. It has a nozzle at the bottom to use for watering your garden.
  • Sub-Surface Harvesting Systems: These are more complex systems that can be hidden below ground.
  • Underground storage vessels, cisterns, or aquifers can be built as an integral part of any of the systems we have discussed or as a stand-alone.
