Water Harvesting 101

A day of record rainfall was indeed welcome in Tucson. However, the storm revealed a problem in my landscape. One of my downspouts directed water into my yard, but it didn’t stay there. A few feet away from the downspout, that water flowed into my driveway, then off my property. Once it’s off property, rainwater becomes stormwater, which can cause urban flooding. So, I’m making adjustments. I’m building a path that will gently suggest a different path for rainwater coming out of this downspout. The goal is to keep that rainwater here, where it can nourish plants as it get absorbed into the ground.

With the summer monsoon season starting on June 15 and running through September 30, it’s time to do the cistern math. If your cistern is below capacity and you’re hoping for rainstorms to come and fill it, how much water will you need? In this episode, I’ll walk you through the calculations.

Back in Episode 59, I announced that I was a gambler, a garden gambler. I planted a pre-monsoon summer garden. Now it’s time for an update. It’s a combination of gardening successes and failures, along with some much-needed problem solving and no monsoon rainfall–yet.

The National Weather Service just released its summer monsoon forecast. It calls for above average rainfall for the entire state of Arizona, especially northeastern Arizona. El Niño is also becoming a factor, which could lead to an active hurricane season. This episode discusses how the second activity of water harvesting, storing rainwater for later use, relates to the forecast.

This is an episode devoted to an organic superstar– mulch! This a layer of material that’s derived from carbon-based life forms like trees, shrubs, bark, and leaves. I’ll talk about the wonderful things that mulch can do for your yard and the plants in it, and explain how you can get mulch. Includes a special guest appearance by a wood chipper.

With the Southwest suffering through a long-term drought – and Colorado River cutbacks looming – it’s time to take a hard look at that thief in the yard. I’m talking about those water guzzling lawns, and why it’s time to remove them. Cities like Las Vegas, Phoenix, and Tucson are offering grass removal rebate programs. I’ll explain how these programs work.

After many weeks of saying that I wouldn’t plant my spring/summer garden until monsoon season, I relented. Because there’s nothing that looks sadder than an empty garden. In this episode, I talk about dry season garden setup, what I’m growing, and, of course, where that garden water is coming from. I also discuss the long-term weather forecast that motivated me to plant this garden.

There was a time when backyard swimming pools were synonymous with life in urban Arizona. Nowadays, one in six pool owners surveyed say they’d like to get rid of their pools. This statistic comes from PoolRemovalHelp.org, a website that guides pool owners through the removal process. In addition to summarizing the features of this website, this episode also takes a look at pool removal rebates available to residents of Scottsdale, Arizona.

Ready to take your water conservation efforts to the next level? This episode is for you! It starts with a plug for landscaping with the drought-tolerant native plants that have been surviving and thriving in the Southwest for thousands of years. It then moves into a more extreme measure–dispensing with irrigation systems that are tied to a municipal water supply. Rainwater storage and laundry water recycling are also featured.

Here in Tucson, we haven’t had measurable rainfall in more than a month. So, I’m calling it. We’re in the dry season. In this podcast, I’ll be covering the dry season to-do list for water harvesters. My focus will be on the three activities of water harvesting: Redirecting rainwater away from where it isn’t wanted to where it is; storing rainwater for later use, for example, during a drought; and recycling “used” water.
