    According to Governing, somewhere between 40% and 90% of the homes in the country have a failing septic system. If you're part of this percentage, you'll need a replacement.

  • What are innovative septic systems?

    First, we have to start from the beginning. For the last several decades soil absorption systems were constructed with stone and pipe.


    Over the last couple of decades infiltration and treatment systems have been researched tested and designed that provide advantages to make the systems smaller and closer to groundwater. These systems are referred to as Innovative/Alternative (I/A) Systems.


    Some of these are infiltration such as plastic chambers that reduce the footprint of the system and are frequently easier to install.


    There are also treatment I/A systems, such as Presby, that the DEP determined to provide a higher level of treatment in the soil absorption system and allow for a reduction in the size and offset to groundwater offset.


    The systems above are considered passive and there are also active systems that replace the septic tank. 


    I am well-versed in many of these systems and use a few in my designs. The passive systems are useful in many circumstances; the active systems are only installed when absolutely necessary.
