No, if you stick your nose down the riser there's a slight musty compost smell like pond water. Nothing like the stench of a regular system. The anerobic bacteria in a standard closed septic system metabolize hydrogen sulphide. That's the stinky smell. But when you aerate sewage, you are imitating what Nature does when it tumbles water over rocks in streams to purify it. Aeration makes aerobic bacteria flourish, and the aerobic bacteria eat the anerobic bacteria. Aerobic bacteria metabolize carbon doixide and that's why there's no stinky smell. Those risers are always open with safety grids on them so no one falls in.
We live in the tropics and most people just have a septic tank, then heavy rains come and things get mixed up!! So looking for solutions that we can bring to the local population whom are basically poor with limited financial resources and then hotels whom have more resources, your system looks ideal for the latter
This is perfect because it's simple.
Even a large aerator uses only 75 watts of power. This is what I use for my conversions. It's available from:
This stuff used to only be sold to licensed septic contractors. But now anyone can get it.
I've been experimenting with running our system half a day instad of constantly and for us it still works fine. However heavier usage for other people would require constant operation.
There is a constant flow of sewage water through the tank just like there is with a regular system, except with our system the water gets composted by Aerobic bacteria as it passes through. After the composted water gets pumped up the hill to the storage tank, it doesn't revert back to foul. It just remains like pond water.
If you have any other questions I'll be happy to help.
