Why Water Harvesting?

Water Supply Sustainability Index (2050)

Practiced for thousands of years across almost all cultures, the process of capturing and reusing rainwater and greywater (from showers and sinks) for non-potable use is fast becoming an important cornerstone for new sustainable practices in the U.S. But why is it important, and why now?

As fresh, potable water becomes increasingly scarce in the U.S., the practice of using it to flush toilets and water landscaping seems almost ridiculous. New methods are now readily available to harvest water in commercial and institutional buildings. The benefits of harvesting go far beyond fulfilling the desire to be “green.” Capturing and utilizing rainwater and greywater can have lasting economic benefits for building owners.

Water Harvesting Benefits


On-site Water Harvesting System Benefits

  • Reusing captured water to flush toilets, water landscaping or support other water-intensive operations can significantly reduce municipal water charges.
  • Wastewater treatment fees and environmental impact fees can also be reduced.
  • Many communities now offer incentives to reduce stormwater runoff or to install reuse systems.
  • Water harvesting can be a key component when designing to achieve LEED certification.
  • Sustainability practices are good for business. Employees, customers and communities support businesses that care about the environment and the conservation of our natural resources.
