Orion Station at Whittier Narrows

LA County Sanitation District has purchased seven Orion weather stations since 2011 – mostly Orion 420s – sited at their water reclamation plants. One of our technicians, Kathryn Hammond, was recently in the area and got a tour of the Whittier Narrows facility.

Prior to her visit Kathryn had spoken with Albert Mata on an installation follow-up with this report: “Albert installed the system. Loves it. Was easy to install.”

Carlos Alfaro, Supervisor of Treatment Plant Operations, gave Kathryn the tour, including the catwalk over the tank. (Whittier Narrows is an open tank wastewater treatment facility.)

Kathryn reports that they use primarily wind speed and direction parameters to help manage for odor based on complaints from the neighbors, as well as the possibility of chemical spills. Using an Allen-Bradley PLC, the systems are monitored with FactoryTalk software.
