Project ID #: 544
Description: This project will install flood protection facilities for the Laguna Treatment Plant (LTP), the Geysers and Reclamation Pump Stations, and Biosolids facility. The flood protection will include stategically placed dikes and a passively activated floodgate across Llano Rd to prevent Laguna floodwaters from flooding to the north into LTP.
