We have a working septic system that we have no complaints about.
However, we'd like to add a guesthouse and more bedrooms and that requires expanding the septic system.
I am happy to do this and happy to spend whatever it takes to do it.
However, I insist on a simple system relying on gravity and no pumps.
The problem is that our available leach field is relatively small ... we need something like 8400 square feet and we have something like 3500-4500 square feet.
The solution suggested is to pump effluent uphill, elsewhere, where other field space can be found.
In general, are there practices that can reduce leach field area?
For instance, could we cascade from one septic tank to another and the resulting effluent is ... thinner ? Needs less leach field?
Interested in any and all comments and suggestions - thank you.
