Maybe start building a fertilizer factory. Raw materials already available.

Cannot say from pictures where the tank is located. Sometimes a tank is so close to the surface that grass above tends to die. So that the field is lower than the tank.

Septic systems typically have no vent. That 'vent' may be a cleanout installed because this has occurred previously. But again, what does the cleanout connect to? Pipe from basement to tank? Or pipe from tank to leach field.

Critical is for vents to exist instead on the roof (ie above bathrooms and kitchen).

Bacteria would not solve anything. A clog of some kind clearly exists. That water would be the daily useage by one person emptying onto sandy (good perking) soil. Virtually all sewage is empyting on the lawn. Nothing less (short of digging it up for inspection/repair) will solve it.

A cheap landlord wants to cut costs - ie bacteria. A landlord who saves money would have called a plumber immediately. With that cleanout, a problem might have been elininated in only one hour.

Rather surprised. In a location that urban, sewers would have long been required by the State of NJ. Your example is why so many towns had to eliminate septic systems. Too many cheatskates wanted to cut costs; refused to fix the actual problem. Caused too many health problems and polluted waterways.

Possible that problem has always existed. That fixing a leach field means he must connect to city sewers. So he just kept sending a guy out with bacteria - to cut costs and ignore an actual defect. To avoid having to connect to city sewers. Do sewers (ie manholes) exist?
