Query: Septic System Owner's Manual

This is a great book to help you understand how septic systems work in general. It is written such that it can be easily understood by anyone. It also discusses how to care for a septic system. What the book does not do is provide much technical data on septic tanks, pumps, etc. If you know little to nothing about septic systems though, this is a great place to begin. I would recommend it to anyone who uses a septic system and wants to know more about how they work and what can cause them to fail.
