What if the water from your shower could help irrigate your landscape instead of going straight down the drain?

Join our Shower Greywater Workshop on October 3 for a hands-on look at how gravity-fed shower greywater systems are designed and installed.

Participants will work through the process of routing greywater from the home into the landscape, while learning how to think through water use, elevation, plant needs, and the layout of a successful system.

This is a great next step for anyone interested in taking household water reuse beyond laundry-to-landscape and learning how more complex greywater systems come together.

📅 October 3 | 8:30 AM-4:30 PM
📍 Vista, CA
💧 $175

Registration also includes an online class on September 30, and the workshop can be applied toward our Water Harvesting Certificate.

Laundry day can be watering day too!

In San Diego’s dry climate, water from regular laundry loads can provide a steady source of moisture through long stretches without rain.

A laundry-to-landscape system diverts that water from the sewer and sends it to mulch basins around trees’ root zones, where it can slowly soak into the soil.

These photos show the progression from before mulch, to completed mulch basins, to the trees’ growth after just one season. The system irrigates fig, mulberry, avocado, pomegranate, persimmon, and citrus trees, along with native plants.

Want to learn how to create a system like this at home? Join us for our hands-on Laundry Greywater Workshop on September 26! Details and registration are available through the link in our bio.

What if one of your home’s most consistent sources of water could help your landscape thrive?

Instead of sending every load of laundry straight to the sewer, that water can be redirected to irrigate trees and other plants throughout your landscape.

Join our Laundry Greywater Workshop on September 26 for a hands-on introduction to designing and installing a laundry-to-landscape system! You’ll learn how to approach greywater safely and effectively, from system design and water budgeting to choosing the right parts, soaps, and landscape applications.

This San Diego homeowner used the City’s Rain Tank Voucher Program to save $800 on an 865-gallon Bushman tank, then used our DIY guidance to plan and install the system themselves.

From prepping the base to installing the leaf filter, first-flush device, and wet-line piping, they did a beautiful job creating a system that turns roof runoff into a resource for the landscape.

The Voucher Program is still open. Apply through Think Blue San Diego, and reach out to Catching H2O to explore tank options + support.

Want to learn the installation process hands-on? Join us September 27 in Vista for our Rainwater Tank Installation Workshop, where we’ll install two 2,500-gallon tanks from the ground up. Learn more through the link in our bio!
