Practical Application

1. Implement conservation measures that reduce water demand as identified in the water audit prior to investigating a rainwater harvesting system.
2. Evaluate whether rainwater collection is viable for site’s climate region and circumstances.
   
   • Determine annual average on-site rainfall and monthly distribution.
   • Reference online resources to estimate post’s potential collection volume.
3. Determine the budgeting and approval process for a rainwater collection and treatment system.
4. Submit funding request to install underground cisterns and treatment facilities requiring significant renovations to the site or building.
