Work continues on the 1.3-million gallon, cement-reinforced holding tank at the bottom of Temescal Canyon Park, part of a City of Los Angeles construction project that began early this year and is expected to be completed in fall 2013. When completed, the $8-million system, funded by the Proposition O Clean Water Bond, will store and divert polluted rainstorm runoff (October through April) that otherwise would flow into Santa Monica Bay. The tank is one of three separate underground structures. During a storm, water will first drain into a diversion structure (already completed under Temescal Canyon Road), and then into a hydrodynamic separator, which separates pollutants such as trash and oil from the rainwater. The debris will remain in the hydro-separator and the water will be stored in the Temescal tank before being sent to the Hyperion Treatment Center. Construction on the separator and pipes to the Temescal tank will start next week. Once the 166-ft.-high, 66-ft.-wide and 30-ft.-deep tank is completed, the grass playing field and playground will be reinstated. Visit: TemescalCanyonStormwaterProject.org or call (213) 978-0317.
