Step-by-Step Septic System Design and Construction Process

​

• Obtain all necessary permits from a local Environment Health Agency having jurisdiction over the property
   

• Conduct Soil Profile Onsite / Test Pits

  • Septic contractor and a professional engineer perform excavations of several pits holes onsite. County inspector observes excavations. Test pits are normally dug with a backhoe to a sufficient depth and large enough to visually inspect the soil layers. Test Pits allow an engineer to evaluate type of soil on site for a proper septic system design.

  • Test pits are back filled after soil evaluation is completed.
     

• Conduct Percolation Test Onsite

  • A percolation test measures water absorption rate of soil at various locations. Percolation testing requires installing perc test holes and measuring and recording water absorption rate. The result of perc test assists a professional engineer to properly design system and a future leach field that becomes an integral part of a septic system.
     

• Development and Design of the Construction Plans for Septic System

  • A professional septic system designer, a licensed Engineer designs a septic system
     

• Submit Septic System Plans to Environment Health Agency for review and approval.
   

• Issuance of Septic System Construction Permit
   

• Construction of Septic System Onsite

  • Stage 1/ Inspection by Engineer and Inspector

  • Stage 2 / Inspection by Engineer and Inspector

  • Stage 3 /Inspection by Engineer and Inspector

  • Stage 4/ Final Inspection by Engineer and Inspector
