Indoor, potable use of rainwater is the most challenging system to get a permit for. Rainwater tanks over 5,000 gallons typically require a permit, while smaller tanks don’t. When researching […]

Harvesting rainwater can reduce our need–and demand–for water transport systems that threaten the health of the water cycle and our local environments.
On any house lot, there are three potential sources for harvesting the rain: Direct rainfall, street harvesting, and roof harvesting.
