I have a brand new septic system and a new 1000 gallon 2 stage cement tank. This is for a cabin that is only used 4 weeks a year with 2 people. Only a toilet is going to the septic.
It will take me a many many years to get the septic tank just full with fluid at this rate.
Should I fill it with water or let it happen naturally over time? I’ve heard that parts of the cement tank not covered with water will deteriorate quicker from the gasses. What is your opinion and why?
