New septic system installation requires proper permitting, soil evaluation, and engineering design to meet state regulations. Licensed installers work with county health departments to ensure systems are sized and sited correctly for each property's unique conditions.
The installation process begins with a site evaluation and soil analysis to determine the best system type — conventional, low-pressure pipe, drip irrigation, or advanced pretreatment systems. Regional terrain variations mean mountain properties face different challenges than coastal installations.
Costs vary significantly based on system type, soil conditions, and site accessibility. Most residential installations include a tank, distribution box, and drain field, with advanced systems required where soil or space limitations exist.
