Fparameters ODUCTION ent is the Phase II Report detailing the design and description of the operational of the wastewatermanagement system for this project. The design and operational parameters are primarily based upon the findings of the testing and analyses protocol described in the previous Phase I Report. Both these reports are made part of the Nitrate Loading/Soil Suitability Study Report to be submitted to the San Joaquin County Environmental Health Department (EHD) in the required format which will constitute Phase III of this project. Discussions on the Operations and Maintenance (O+M) of the system will also be submitted in the Phase III Report. As referenced, it will be a number of decades before City of Stockton sewer will be installed to serve this area. Consequently, the design and operations of the wastewater treatment and soil disposal system have been engineered to theoretically operate until City sewer arrives. However, the new septic tanks and associated appurtenances can be considered to have theoretical life spans of approximately 50 years or more before replacement. The existing grease interceptor tanks and septic tanks that currently serve the Restaurant are in severe substandard condition, severely undersized, and must be replaced with properly sized and manufactured tanks. The existing leachfield is directly west of the Restaurant and must be in extremely poor condition given the amount of organic material observed discharging into the soil environment from the tanks. This Report is sequentially structured, beginning with influent and effluent flow volumes from the existing Omelet House Restaurant and future ARCO Service Station, septic tankage and related information, followed by Package Treatment Plant information, and ending with effluent disposal to the soil environment. II. INFLUENT/EFFLUENT FLOW VOLUMES A. Omelet House Restaurant Influent wastewater originating from the Restaurant consists of two separate waste streams: One for oils and grease contained in food prep, dishwashing,prep sinks and floor drains, and one for human wastes. The volumes that can be attributed to each waste stream are unknown and indeterminable. The Restaurant receives domestic water from California Water Service (Cal Water). Consequently, water meter readings for this facility were obtained from the Applicants. Water delivery by Cal Water is measured in 100 cubic ft(748 gallons) increments which are referenced as CCF. Table 1 below illustrates the monthly water deliveries since the Restaurant was opened by a new operator in August 2013. Water usage in 2013 is not representative of current flows and is referenced as not applicable (N/A) in the Table. We see a steady increase in water usage between the years 2014 and 2016; however, as it is impossible to delineate water usage referenced in the above two waste streams, a comparatively small percentage of water usage in the summer is used for landscape irrigation. This is also indeterminable,but a low volume since the landscaping is a very small area. Page 2 of 8 Chesney Consulting
