If it's a conventional gravity system, yes! The homeowner must take a course from Public Health and pass the operations & maintenance (O&M) test ($20). The form for reporting inspection results will also be provided at that time.
Inspections cost less than pumping, but the price may vary depending on the type of system you have. As private industry is providing this service, we cannot regulate their fees, but encourage you to get more than one quote before selecting an O & M specialist.
“Gray water” means sewage from bathtubs, showers, bathroom sinks, washing machines, dishwashers, and kitchen sinks. It includes sewage from any source in a residence or structure that has not come into contact with toilet wastes.
