Rainwater Collection

Rainwater harvesting sustains the environment, while being economically profitable. According to the EPA, a government survey shows that by 2013, 36 states are expected to have areas with water shortages. Rainwater harvesting both reduces demand on the regular water supply and helps reduce runoff which contaminates streams, rivers and lakes. Rain that falls on roofs and other impervious surfaces is more likely to travel as overland flow than infiltrate the soil to become groundwater. Overland flow carries petroleum products, fertilizers and other pollutants directly to surface waters. This decreases the quality of surface waters and decreases groundwater available for public use. Rainwater harvesting collects this water from the roof, before it collects most contaminants, reducing the demand on public supply and decreasing runoff.

One inch of rain on a 1,000 sq ft roof yields 620 gallons of rainwater.
That’s enough water to:

• Fill a bathtub more than 6 times
• Take 31 showers
• Wash about 20 loads of laundry

How it works.
