Do mound systems really work?
For some reason, there appears to be a myth that exists about mound systems not working. You should know that mound systems work every bit as well as an inground (conventional) POWTS. The primary difference between the two systems is that mound systems are pressurized above-ground systems and the conventional inground system is below ground and typically not pressurized.


As far as system performance is concerned, a pressurized system typically will perform better than one that is not, because the wastewater is dosed over the entire absorption area versus being distributed over a small area as in the conventional gravity system.
