Sutter Home Winery (Trinchero Family Estates) is constructing a 150-acre, $300 million-dollar winery expansion in San Joaquin County in Lodi. The expansion includes over 700,000 SF of building space spread out over 10 different structures. Given the rural nature of the entire 280-acre campus, the utilities are self-contained with water supplies coming from wells and stormwater sources. Disposal methods include utilizing retention basins, and the sewer system is serviced by a new 12,500 GPD mounded leach field system dosed by 12 sump pumps, several septic tanks, and three miles of combined force mains. To enhance the efficiency of the leach field system a drip system was employed which not only increased the system’s ability to dose effectively it was half the cost of a chamber style system. Project challenges include infiltration into the system due to high groundwater levels in the area. To combat this, Siegfried designed all catch basins, manholes, and pipes to be completely watertight. All structures are designed with pre-molded fiberglass and the pipes are either solvent weld PVC or extra tight gasketted PVC. The campus is fortunate to have a number of high-yield and good quality water wells that are used for domestic and firewater. Due to the number of structures and the size of the structures, the system is supported by dual 300,000-gallon water supply tanks and two pressure boosting stations. With over 6 miles of the storm, sewer, water, fire, process waste, and conduit pipes, designing the infrastructure in high groundwater and a sustainable way poses challenges that the Siegfried team is readily equipped to handle. Coupled with the miles of infrastructure are numerous water quality systems and basins that filter, clean, and infiltrate the valuable stormwater.
