Innovation: Turning rainwater into a lifesaver amidst California's drought crisis

Amid California's unprecedented drought, recycling has taken on a crucial role in water conservation, with businesses across the state finding innovative ways to use water more sustainably.


Reusing wastewater holds significant benefits, including increasing local water supplies, improving water quality, conserving energy, and reducing wastewater discharge and disposal costs. While domestic gray water (used household water excluding toilets) is part of the solution, the majority of recycled water comes from treated municipal sewage or wastewater.


Buzz Boettcher, inspired by his experiences in offshore sailing, developed a system at the Santa Monica Pico branch library to collect rainwater from the roof and convert it into gray water. Essentially, this system repurposes water that would typically flow down the gutter and uses it to flush toilets. Boettcher's system can fully replenish the tank with as little as two inches of rain, a significant feature in drought-prone Southern California.


Reusegraywater innovative approaches to water recycling are also evident at places like the Eataly market in Century City, where water-saving is a top priority. Their technology recycles all water that flows through restroom sink drains, subsequently using it for rooftop plant irrigation and toilet flushing.



It's important to note that gray water is not suitable for drinking. Boettcher has installed such systems in households and even developed solutions for recycling water in specific industries, such as truck wash water in Houston.


While these devices can be expensive, the urgency of California's severe drought and the need for water conservation make them a worthwhile investment. Experts suggest that the current drought in the region is the most severe in 1,200 years, underscoring the importance of utilizing water resources efficiently. As Boettcher aptly points out, using clean, potable water for flushing toilets is wasteful.


Efforts to change fundamental sustainable goals within global society have already gained traction among institutions, governments, and individuals. These shifts go beyond superficial "greenwashing" and are driving the adoption of circular economy principles and responsible water management in arid regions. They are essential for preserving water systems and ensuring they can sustain human and environmental life.


The water consumption statistics for the average four-person single-family home in California are indeed eye-opening. It's alarming to consider that a significant portion of this water is used for non-potable purposes, such as landscape irrigation, which involves using clean drinking water to water plants and lawns. This practice highlights the need for more sustainable water management and the importance of repurposing water for various purposes, especially in regions facing water scarcity.


The fact that a family in California uses nearly 11.000 liters of water per month for flushing toilets emphasizes the inefficiency of using clean, potable water for tasks that don't require it. This underscores the importance of implementing water-saving technologies, like gray water systems or water recycling solutions, to make better use of available resources and reduce the wastage of precious drinking water.
