What is Rainwater Harvesting System?
A rainwater harvesting system collects and stores rainwater from rooftops for reuse in irrigation, toilets, or other non-potable applications. Advanced systems may also filter water for potable use.
Why Rainwater Harvesting System Matters in Real Estate
It matters in real estate because rainwater harvesting reduces water costs, eases demand on municipal systems, and supports sustainability certifications. It is increasingly integrated into green building practices.
Example of Rainwater Harvesting System in Action
A commercial building installs a rainwater harvesting system to irrigate landscaping and flush toilets, reducing utility costs and environmental impact.

Average and median describe different aspects of the same month’s transactions. Both are affected by the mix of homes sold.
Category averages compare different homes and locations; the gaps are not estimates of the cost to upgrade an otherwise identical property.
The five categories shown account for 5,000 of the board’s 5,057 sales. The remaining 57 transactions were in other housing categories.
Monthly observations are not seasonally adjusted. Active listings count properties available at month-end; they are not construction inventory.
Average and median prices share one dollar axis. These unadjusted transaction measures do not control for changes in the homes sold.
TRREB’s 416/905 categories compare the apartments sold in each area. The difference does not isolate a location premium for equivalent units.
