Assessment For Septic Tank Pumping Frequency
Completion of this form is one of two options you have for meeting requirements of the Lewis and Clark County On-site Wastewater Treatment Regulations. Your second option is to hire a certified septic operation and maintenance service provider, who will submit an inspection report on your septic system to the health department for review.
How often a septic tank needs to be pumped depends on the system design and how your household uses the system. Complete this assessment to determine how often you should have your septic tank pumped.
