How are septic systems designed? To design a septic system, we need to gather information.

​

What type of structure will the system serve, residential or commercial?

• For residential:

  • How many bedrooms does it have?

  • How many bathrooms does it have?

  • How many people will be there?

  • What water using devices are in the dwelling?

  • Does it have a garbage disposal or pump in the basement?

  • Is there an in-home business?

  • Is there any planned expansion of the residence?

• For commercial:

  • What is the building going to be used for?

  • How many people will work there?

  • Will there be multiple shifts?

  • Is there any industrial waste being generated?

  • Then a site visit is required, at the site:

  • Where are the property lines?

  • Are there any wells?

  • Are there any easements on the property?

  • Is there any compacted or disturbed soils on the property?

  • Where are potential suitable soils located?

  • Elevations and contours must be determined

  • Soil observations (borings or pits) must be conducted.

  • Measurements of the available area must be done and recorded

  • A site sketch must be completed

  • Sizing of the soil treatment system must be calculated

  • Calculation of the type of system along with the size and type of distribution needed.

  • Pump & pump tank sizing if a pump is required.
