Looking for some advice. I'm having a party at a rental house with 30-35 attendees for about 4-5 hours. The septic system is apparently designed for 12 people (the house sleeps about 10). Party guests aren't staying over so won't be showering etc, but the 6 people renting the house will be staying for a few days before and after the party. I'm trying to understand the risk of a septic problem, as explained in this article: Additional water inputs from bathroom use during a large party without pre-planning can cause an unwanted surprise for your guests.
As I understand it, even too much water volume alone can overwhelm the system because it takes time to process and drain off the wastewater. Hydraulic overload seems to be the technical term. But how much time are we talking about? E.g. would showers taken the morning of, or day before, or multiple days before, increase the risk of a problem during the party in the evening? Or is several hours enough time for water to work its way through?
Aside from avoiding running a lot of water immediately before the party, and telling attendees to be conservative with water use and only flush toilet paper, is there anything else we can do to mitigate risk?
House is in a coastal area if that matters.
It's too late to rent a portable toilet unfortunately.
