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.
