When you need a new septic system
New installations are typically needed for new construction, full drain field failure, major system expansion, or replacement of an aging system that no longer meets local standards.
The installation process
This usually includes site evaluation, system design, permitting, excavation, installation of the tank and drain field, and final inspection before the system is approved for use.
What affects installation cost
Cost can vary widely based on household size, soil conditions, lot size, drain field design, and excavation challenges.
