A Review of the Top Rainwater Harvesting Systems
Last Updated: Mar 17, 2025When considering the essential elements of the sustainable home, most people begin to think about renewable energy options and energy efficiency home upgrades. In the United States, the residential sector contributes almost 12 percent of all greenhouse gas emissions. These emissions, according to the Environmental Protection Agency (EPA), stem “from fossil fuels burned for heat, the use of certain products that contain greenhouse gases, and the handling of waste.” Given this reality, shifting to more energy-efficient homes that rely on solar panels and other forms of residential renewable energy technologies is a crucial element towards making our homes more sustainable and resilient.
But what about the water we use in our homes? The vast majority of homeowners across the country do not know where their potable water comes from or how it gets to their homes. As long as water comes through the faucets and showerheads whenever we turn them on, most people are content in that ignorance. Transitioning to more efficient water technologies such as dual flush toilets, low flow showerheads, and more efficient sprinkler systems is undoubtedly essential. However, taking that extra step to capture, store, and use the rainwater falling on the roof of your home should become another crucial aspect of environmentally friendly homes.
