Why Rainwater is Perfect for Your Landscape

Conserving Precious Potable Supplies

Irrigating with rainwater frees up drinking water for what truly requires it. In many regions, outdoor use accounts for a large share of household demand. Shift even a portion to rainwater and you will see bills drop and resilience rise.

Designing the Catchment and Storage

Estimate potential yield using the rule of thumb: one inch of rain on one square foot yields about 0.62 gallons. Multiply roof area by average storm depth and efficiency to right-size tanks without overspending. Share your calculations with us.

Keep leaves out with gutter guards and inlet screens. A first-flush diverter discards the initial dirty roof wash, protecting storage from fines and pollen. Cleanable parts save headaches later, so choose components you can maintain easily.

Poly tanks are affordable and durable, metal tanks are stylish and long-lasting, and underground cisterns save space. Place tanks upslope for gravity-fed irrigation and near downspouts for short conveyance runs. Shade improves water quality.

Delivering Water Efficiently to Plants

A tank set on a sturdy stand can drive low-pressure drip. Use pressure-compensating emitters rated for low head. Short, direct runs and simple manifolds reduce friction losses, delivering steady flow to roots where water matters most.

Delivering Water Efficiently to Plants

Pair rainwater irrigation with timers or moisture sensors so you apply just enough. Pause schedules after storms and prioritize zones with young trees or perennials. Comment with your favorite controllers and settings for tough summer weeks.

Water Quality, Safety, and Stewardship

Install a calming inlet to settle sediment, then drain the quiet bottom zone annually. A floating outlet draws the cleanest water near the surface. Schedule a spring inspection and share your maintenance checklist with fellow readers.

Stories from Yards That Harvest Rain

Maya installed two 200-gallon barrels beneath a 300 square foot roof corner. One storm filled both, and her summer water bill dropped by a quarter. She now hosts weekend tours to encourage neighbors to try simple, modular setups.

Stories from Yards That Harvest Rain

A PTA crew added a 1,000-gallon cistern and drip to raised beds. Students charted rainfall and flow, learning data skills while tending tomatoes. Share this post with your school and tell us if your district would welcome a volunteer build.

Maintenance Routines Through the Seasons

Clear gutters, rinse screens, and test your first-flush diverter. Confirm tank valves move freely and overflow paths are safe, away from foundations. Share your pre-storm checklist and we will feature the most helpful routines next month.

Maintenance Routines Through the Seasons

Check for slow drips, emitter clogs, and algae hints at lids. Flush lines briefly and verify timer programs match plant needs. A half hour now saves gallons all summer, especially when heat waves push irrigation systems to their limits.
