What does septic system design cost?

Design fees vary with site difficulty; plan on several hundred to a couple of thousand dollars including the required soil testing. On a difficult site, an engineered design costs more but is often what makes the lot buildable at all.

Those are national ranges. The Septic System Design cost guide explains what moves the price, and local quotes set the real number.
