California’s been in a drought for years, and it’s not letting up. That means outdoor watering restrictions and urgent calls from state officials to cut back on water use. Even suppliers are seeing cuts because there’s just less water to go around.

You might think this means dead plants, brown shrubs, and even shorter showers. But that doesn’t have to be our reality. The perfect solution for Californians to cut their water use is to rely on greywater systems. It’s a relatively inexpensive option that’s getting more attention, but it still deserves more recognition.

How it Works

A greywater system is pretty simple. It takes water drained from your showers, sinks, or laundry machines and repurposes it so you can use it to irrigate parts of your yard. The simplest systems can be installed in minutes and start working right away. Experts say the investment is worth it because you’ll quickly see savings on your water bill.

Is the Technology New?

Nope, greywater systems have been around for decades. So, it’s not new at all. Experts believe that in a state like California, where droughts are so common, there isn’t a statewide push for people to install these systems, even though they can help a family of four save thousands of gallons of water every year.

Lack of Incentives

Newsha Ajami, a water expert at Lawrence Berkeley National Laboratory who served on the Bay Area Regional Water Quality Control Board, put it this way: “There is no real blanket guideline available right now, and there are not a lot of incentives out there either to get people to do this.”

Even locally, the incentives aren’t very appealing. Some counties, like Santa Clara County and San Francisco, offer rebates, but many other counties and water districts don’t offer any incentives at all.

Rising Residential Water Consumption

According to the University of California Division of Agriculture and Natural Resources, watering your yard accounts for about 50% of annual residential water consumption across the entire state.

Experts believe that during a drought, we could use that water much better. Justin Burks, a water conservation specialist at Valley Water, said, “Our plants don’t need drinking water.”

Success Stories

A 2012 study by Greywater Action, a Bay Area-based advocacy group, showed that homes in the Bay Area and Monterey County that installed greywater systems reduced their daily water consumption by about 17 gallons per person. That could mean an average household saves about 14,500 gallons each year.

Other Important Benefits of Greywater Systems

Another important benefit of using greywater is that you can keep growing trees and plants in your yard. This provides food and shade, and it supports wildlife. Basically, greywater systems save both water and money. They can also be good for the life in your backyard.

A 2012 study by Greywater Action looked at 83 greywater systems in San Francisco and the Monterey Bay area. It found that the systems didn’t impact boron, salinity, or other nutrient levels compared to soils that hadn’t been irrigated with greywater.

In her 2021 master’s thesis for San Jose State, water researcher Sara Khosrowshahi Asl discovered that greywater didn’t negatively affect soil quality. For systems that had been in place longer, the soil quality actually improved, and the amount of newly built-up nutrients increased.

Khosrowshahi Asl noted that the most successful greywater efforts use biodegradable or greywater-friendly detergent. Most people used it. She said, “You don’t need to add fertilizers anymore. Just the detergent itself and the things that are in the clothes add the nutrients to the soil.”

History of Greywater Systems

For many years, reusing greywater was illegal in California because people considered it the same as blackwater, which is wastewater from toilets.

Things started to change in the 1990s when California legally updated its plumbing code to allow greywater reuse. Still, there were several restrictions on what that could look like.

In 2009, California allowed simpler greywater systems to be installed without a permit, as long as certain requirements were met. This included easy-to-use systems like the laundry-to-landscape model. These systems became more accessible, according to Laura Allen, a founding member of Greywater Action who has worked on this issue for decades.

Lack of Knowledge is Evident

A lack of knowledge is one of the main reasons more Californians, and people worldwide, aren’t using greywater systems. They don’t even know it’s an option. Greywater systems are less obvious than, say, solar panels on roofs. So, most people don’t talk about them with their neighbors.

When more people know about greywater treatment systems and use them, awareness will grow. More marketing efforts from brands like AMPAC USA can also help.
