Rainwater Harvesting Systems for Colorado Homes

Rainwater harvesting helps Colorado homeowners cut water bills, ride out droughts, and rely less on municipal water supplies. Sun House System designs and installs residential rainwater systems across Littleton, Denver, and the Colorado Front Range.

Our Reality

How Rainwater Harvesting Works

 A rainwater harvesting system is simpler than most people expect. Rain falls on your roof, travels through your gutters, passes through a pre-filter or first-flush diverter that removes debris, and is stored in a barrel, cistern, or tank. From there, it can be gravity-fed or pumped to wherever you need it — vegetable gardens, lawn irrigation, drip systems for trees and perennials, or ornamental landscaping. Every system Sun House System designs is sized to your roof area, your average annual rainfall, your storage goals, and your end-use pattern.

Benefits for Front Range Homeowners

Colorado is a semi-arid state with growing water-supply pressure, periodic drought restrictions, and rising municipal water rates. Rainwater harvesting helps in four concrete ways. 

  • It reduces your potable water consumption for outdoor use, which is often the single largest line item on a summer water bill. 
  • It makes your landscape more resilient during watering restrictions — your tomatoes don't care that the city has moved to Stage 2. 
  • It reduces stormwater runoff from your property, protecting soil and reducing the risk of local flooding. 
  • Captured rainwater is naturally soft and free of chlorine, which is better for plants, soils, and beneficial microbes than treated tap water.
