Citybuilt.org got a behind the scenes look at the LA County Sanitation District’s wastewater treatment facility on the grounds of the San Jose Creek, just off the 605 freeway this past Saturday – it was enough to make any lover of infrastructure and monster machines wilt a little in the knees. But that’s not all . . we also toured the Puente Hills landfill (across the highway from the treatment plant) – formerly the San Gabriel Valley dump – and saw the work they are doing with their highly successful PERG (Puente Hills Energy Recovery from Gas) program, in which methane produced by the seepage of buried trash is pumped into an adjacent power plant. The methane-fueled plant can produce enough energy to power 70,000 neighboring households – it’s a beacon of green infrastructure indeed, and its right in our backyard. It was a fascinating day out at the sewer plant and the dump – if you’re into that kind of thing. And we know you are.
