But what really fascinated me about the Tillman Water Reclamation Plant was where its recycled water went after it was cleaned up.
Everybody poops, and in a sprawling metropolis as big as LA, all that poop water has to go somewhere – so why not a garden?On Monday, February 23, join field agent Sandi Hemmerlein (me!) on an epic voyage to a wastewater treatment plant in Van Nuys, whose recycled water reaches its final frontier either at 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 which is irrigated with reclaimed water from the plant.If you join the Los Angeles Obscura Society on this excursion, you'll come out smelling like a rose...or, at least, like bougainvillea.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 poop 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 as Star Trek's Starfleet Academy.On our private hard hat tour of the treatment facility, one of the plant's own engineers will show us how they separate solids from the wastewater, which is then filtered and disinfected in a process that takes nearly a half day. We'll then tour the 6.5 acre garden, which was designed by world-famous designer Dr. Koichi Kawana, also responsible for Japanese botanical gardens at the Los Angeles County Museum of Art and San Diego's Balboa Park. Kawana fashioned this garden after “stroll gardens” constructed during the 18th and 19th centuries for Japanese Feudal lords.On our stroll, we'll witness the 2.75 acre lake that 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.
Join us for an in-depth exploration of laser technology and a live demonstration of Laserium, the world's first continuously-running laser entertainment – in the actual "House of the Laser."Ladies and gentlemen, we are about to be floating in space.On Thursday, March 19, join field agent Sandi Hemmerlein (that's me!) on a cosmic adventure with the people behind the great laser light shows at Griffith Park Observatory (1973-2002) and all over the world, in the studio where many of those shows were designed and choreographed.In this intimate setting – a private event just for the Los Angeles Obscura Society – we'll delve into the retro-futuristic technology pioneered by Ivan Dryer, the father of the commercial laser light show industry. Dryer, once an aspiring filmmaker, first explored the potential artistic application of lasers at CalTech in 1970 and soon founded Laserium, recontextualizing one of the era's newest developments in science and medicine as "music for your eyes."Laserium's shows are a three-dimensional, abstract visual spectacular featuring spirals, clouds and aurorae set to a variety of styles of music. In addition to a demonstration, we'll also have the unique opportunity to find out how the patterns of light are created and executed, with an after-show Q&A with Laserium's principal creative staff and even one of the Laserium elders. We'll learn the science of laser physics – Light Amplification by Stimulated Emission of Radiation – as well as the technology of all the special effects that go into the laserists' visual light shows, which have been experienced by over 20 million people internationally.All Obscura Society attendees will receive a free ticket for a future scheduled Laserium show (pending availability), a $15 value.
Light refreshments will be provided.
