How do so many people, who know so Little. just say so much that is just incorrect.
If installed correctly - See Post #2 - https://www.wikihow.com/Construct-a-Small-Septic-System
- as to How to do this correctly - and it will be fine.
Tank needs to be solid and the two tanks will make it work as it needs to - so it can do it's work - Drain field needs to be Big Enough so it can do it's work.
The normal house is in our area (Maryland) designed for 275 gallons per day thus - they usually use 1,000 gallon tanks and hundreds of feet of drain fields, depending on the percolation of the soil. (7X275 = 1,925)
When the DW and I Boondock - we can survive for 7 days on 100 gallons of Water - that is 14 gallons per day.....
So just doing the Math two Tank system = 110 Gallons at 100 gallons per week.
A house uses 1,925 gallons and has a tank with 50 Per cent of the used Capacity. (1,000 gallon tank and 1,925 gallons per week)
So just using this simple logic.............the Two Tank system is an Over Build for the Needs of the Boondocking RV'er -
Sorry, it just rubs me wrong to see so much BS - will one tank work - Not likely - will two tanks work if installed as directed in post Number 2, if with soil that percolates - Most Likely for an RV'er - Not likely for a House.
ps - I spent 30 years in the Utility Business - installing and maintaining Sewer and Water Lines.....Hundreds and Hundreds of Miles of Sewer - Poop Does Stink no matter how you build the system. -
