Aerobic Aerobic - aerobic systems, like LPD must also be designed by an engineer or registered sanitarian. These systems can typically be installed in any kind of soil conditions or slope constraints. The aerobic systems can be installed below the ground at shallow depths or be sprayed on the surface of the soil. Aerobic Treatment Units are different from conventional septic tanks in that there is an aeration and clarifier process that happens inside the unit. These systems may require disinfectant before it is introduced to the soil. There are a few more working parts on an aerobic treatment unit compared to LPD or Conventional but also many more advantages. The effluent discharged from these systems has already been treated and will require less work from soil and therefore less chance of contaminating the water source. Hiring a reputable licensed maintenance provider is a must to keep your system working in top notch condition.
