My husband's specialty is a sub-category of environmental science. He has a master's degree in Environmental Health Science, and a B.S. in chemical engineering. Not just sewage treatment, water treatment and water purification involve processes in addition to sewage treatment, for example, water filters for purifying drinking water in the home; filters and devices for removing spilled oil from seawater; filters for fish tanks and ponds. Lots of new patents on stuff for koi ponds, which are quite popular these days. Lots of new patents on water filters you put on your faucet. The invention you discuss is called a "package plant." It is a commercial reality. Try inputting "package plant" and "sewage treatment" on your search engine. Fairfax County allows them, but my impression is that they are much more expensive than a passive septic tank and field, and require more frequent maintenance. They do a better job of cleaning the effluent, and if I had a septic system, I'd have a package plant for environmental reasons.
