How to Harvest the Rain

Harvest in the Rain

With all the recent rainfall, you might be fascinated to know you can capture the water falling in sheets to use later as irrigation water for your lawn and garden. What comes down doesn’t all need to run down the yard, into the street, and go into stormwater drains. With some planning and small changes to your landscaping, you can guide the water around your yard and “bank” it in swales or capture it with a traditional rain barrel.

Las Cruces Utilities (LCU) models passive rainwater harvesting at its administration building’s Demonstration Garden at 680 N. Motel Boulevard. “Passive rainwater harvesting is modifying your landscaping to hold onto the water longer,” explained Rhonda Diaz, LCU Water conservation program coordinator. “You build pathways for the rain to stick around instead of draining away, giving it a chance to really soak into the soil.”

At LCU, there are berms - think long, small hills – built into the soil of the Demonstration Garden to guide rainwater that comes off Motel Drive. Those berms direct the water into a holding pond to soak into the surrounding garden. The location is free and open to the public and also shows a whole bunch of different plants, shrubs, and trees that are drought-tolerant and require less watering.

Las Cruces resident Dr. joni newcomer (sic) has a different setup at her home. She uses rain barrels to catch rainwater run-off from her roof making it an active rainwater harvesting system. Her barrels - placed strategically to not only capture the water - but also to water different sections of her yard, also have a top to make sure that mosquitoes don’t make generations of families, and a spout where she can attach a hose.

“Most people would be surprised to see how much rain accumulates in these barrels in one storm,” she said. “It’s all water easily reused on your garden instead of it going through the city’s system. It’s perfectly good for your plants.”

Rain barrels are available in the garden departments at home improvement stores including Walmart, Lowe’s, or Home Depot. Each is constructed with a top and a spout for a one-time investment of $70 to $100.

The Garden is free and open to the public to show how residents and businesses might modify their own landscaping.
