Questions
Septic
How is the system size determined?
Bedroom count sets the design flow; conditioned square footage becomes controlling only on larger homes. Soil class then determines how much disposal area that flow requires.
Is a manufactured home sized differently?
No. Same bedroom count, same sizing as a site-built home.
Can I choose a cheaper system type?
Only within what your soil legally allows, and the area requirement does not change dramatically between types. Soil is the real driver.
What is the difference between conventional and aerobic?
Conventional disposes to soil without treatment and carries no state-required maintenance contract. Aerobic treats first, which lets it work where conventional cannot, and carries ongoing maintenance and reporting obligations.
Are drip and spray different systems?
They are both aerobic dispersal methods. The treatment is the same; how the effluent is distributed differs, and the lot usually decides which fits.
Why do I need a site evaluation first?
Because soil determines both the size and the legal type, and soil cannot be read reliably from a map.
Still have a question?
Call and ask. We would rather answer it now than have you find out the expensive way.
