@Dan StrandbergUnless the process is different there, the inspection should include identifying the type of septic tank and drain field/system; evacuation; checking for cracks/roots/deterioration; type of material tank is made of; if it’s level; size of the tank- is it large enough for the number of bedrooms; whether it closes properly; whether water run through it drains properly; that the ‘hatch’ closes properly; setbacks from the home/boundary etc; and whether both septic and drainage meet any existing regulations.Hope this helps!
