Sci-Fi Sewage Sanctuary - Atlas Obscura

Van Nuys, CA

Sci-Fi Sewage Sanctuary

Take part in National Infrastructure week! Tour a water recycling plant better known as Starfleet Academy, and the Japanese garden it irrigates with toilet water.

Everybody poops, and in a sprawling metropolis like L.A., all that poo water has to go somewhere—so why not a garden?

Join Field Agent Benjamin Harmon on an epic voyage to a wastewater treatment plant in Van Nuys, whose recycled water reaches its final frontier at either the Hyperion Treatment Plant in Playa Del Rey, or next door in its own Japanese Garden—which is aptly referred to as the "garden of water and fragrance," and is irrigated with reclaimed water from the plant.

One of the leading producers of reclaimed water in the San Fernando Valley, the Donald C. Tillman Water Reclamation Plant recycles as much as 26 million gallons of toilet water per day, relieving the overburdened portions of the wastewater collection system between the San Fernando Valley and Hyperion. Although few get to tour its sprawling campus, many recognize its futuristic administration building as a shooting location for numerous films and television shows, including Star Trek's Starfleet Academy. 

On our private tour of the treatment facility, the very knowledgeable (and aptly named) director of the Japanese Garden, Gene Greene, will show us the various processes used to separate solids from the wastewater, filter the water, and disinfect it. The entire process takes nearly a half day.

Afterwards, we'll embark on an exclusive guided tour of the Japanese Garden by Japanese Garden board member Michael Fritzen, whose credits include work with the Natural History Museum of Los Angeles County, Los Angeles Zoo, Autry Museum, the Huntingtonthe Skirball Cultural Center, and the L.A. Puppet Festival.

Michael will lead us through the 6.5-acre garden, designed by world-famous designer Dr. Koichi Kawara, also responsible for Japanese botanical gardens at the Los Angeles County Museum of Art and San Diego's Balboa Park. We'll learn about Japanese landscaping, and how Kawara fashioned this garden after “stroll gardens” constructed during the 18th and 19th centuries for Japanese feudal lords. 

On our stroll, we'll take in the 2.75-acre lake, which is filled with the plant's treated water, and a waterfall, which is the main entry of water from the reclamation plant into the lake, where about three million gallons of reclaimed water pass through daily. 

After the garden tour, we will sit back and relax in a Japanese pagoda as Michael teaches us how to make Japanese scroll paintings. We will each take one home with us. 

This event is part of National Infrastructure Week. Infrastructure Week is a non-profit organization that convenes for a week of education and advocacy highlighting the state of our nation's infrastructure—roads, bridges, rail, ports, airports, water and sewer systems, the energy grid, telecoms, and more—and all the projects, technologies, and policies necessary to keep these vital parts of life humming along.
