Residential Water Harvesting
• Requires a shift from traditional demand management
• Over 1,200 rebates since 2013 & currently largest $ rebate program
• Significant investment for utility & customers
• Understanding scalable solutionsWe find ourselves with an opportunity to re-think how we manage rainwater...
• The water is free.• The water is better for my plants.• I need to deal with a flooding problem.• I want more shade.• I want a garden.• I’m tired of my water bills going up.• I think it’s the “right” thing to do.• I don’t think we should depend on water from faraway rivers.
“I want to harvest water because… ___________________”
