I'm doing more research into this. What are the pros and cons with regards to maintenance? How often and what does it need attention?
I am thinking of combining the kitchen and bathroom as great water. It seems that I need a grease trap and a settling tank. Ground temp in winter about 50's deg F. Air temp in winter can be hovering 40's deg C for a couple months.
Design is for 4 people/ household. Anyone has experience in this? Much appreciated.
