Active Sewage Treatment Systems
Anybody know about the latest requirement from SEMERNAT for sewage treatment systems that require active aeration and other "treatments"? This has
been stipulated in our environmental impact permit and I found a couple of systems, both of which take a 1/2hp electric motor to run which will
totally killl my solar system. Apparently It's no longer OK for a simple two chamber tank with leech field. HELP

What could be more efficient than an adaquate size, healthy septic system?
You folks down there are sooo over-regulated. Seems like everybody just wants a piece of your wallet.

Sorry to tell you, but this is not a BCS thing, it is a Mexico thing. Seems they learned from the US.

Up here NOB we have always built 3 chamber septic tanks with either a cesspool or leech line system after the tank. First perked the ground to make
sure it would work. The systems I have seen SOB were never built this way.

I'll bet they'll even sell you a "special" permit for one of these:

Can you share your experience in going through the process to get your environmental impact permit please? Who did what and for how much?

Hey, that Mighty Mac looks like the hot ticket. Only uses 60 watts of power. Thanks for the lead.

Aerobic or cloth filter pre treatment. Whether a simple gravity system (tank and leach field) works to treat, rather than to simply dispose effluent
depends upon the quality of soil and perc rates. In ideal soil, and with 3 feet to groundwater the gravity system is sufficient...it is actually the
soil below the system that ultimately treats wastewater. The tank performs a first stage treatment, but it's the soil that does the job to prevent
untreated effluent from entering the water table.
If you build a gravity system in sand, it seems to work well because it simply disposes. You would need 20 feet from groundwater for it to treat
effluent in most sandy soils.
With an aerobic system, you are best off to add uv treatment to get rid of pathogens, but aerobic systems do not work well with intermittent use. So,
unless the home is occupied pretty much full time, a cloth filter system is best. I think they are best anyway, and work well with drip irrigation
instead of traditional leach lines. See advantex systems by Orenco in Oregon. They are used a lot in difficult areas, and have a good track record.
Probably more than you want to hear...but, I have learned a lot about systems in Stinson Beach over the last 20 years, as a director of the water
district that monitors and oversees construction of systems. I've done a couple of courses in small systems, as well. All systems in SB are on-site.
