House is located on top of a hill. It has a well with a septic tank. A wedding event is taking place and there is some concern about usage. It will be about a two or three hour event with about 60 people. There will be some food and drinks at the event. The house has three bathrooms but only two will be available for guests. Will this cause strain on the system? Should a porta potty be rented? Trying to avoid renting one to save costs on wedding.
