The freeze deadline
Burleigh County's septic permit says in capital letters that no work shall be conducted after the ground has frozen. That means new systems and repairs have to be finished before freeze-up.
Burleigh's design numbers show how serious that is: a 4-foot frost line, a winter design temperature of minus 18°F and an air-freezing index of 4,000. DEQ's proposed statewide rules, not yet adopted, would also stop installs once frost reaches the top 6 inches.
Why systems freeze
NDSU Extension's Tom Scherer lists thin snow cover, dry soil, long cold spells, poor pipe slope and vacant homes as the main causes. A cabin or second home left empty is at the most risk.
What to do now
Lay hay or straw at least 1 foot thick, extending 5 feet past the edges of the system. Add snow fence so snow stays on top, fix dripping fixtures, and don't drive on the area or plow snow off of it.
NDSU also recommends pumping before winter. Winter spreading of septage is limited too: between 15 November and 1 April, land application is restricted to under 8 inches of snow and slopes under 6%, so trucks may need to haul to a plant instead.

Frequently asked questions
Can a pumper empty my tank in January?
Sometimes, if the lids are exposed and the truck can reach them, but frozen ground and buried lids make it harder and slower. October is the safer time.
What should I do if my system freezes?
Stop running extra water, keep the cover on, and call a septic professional.
When does the ground freeze around Bismarck?
It varies by year, but with a 4-foot frost line, plan to finish pumping and repairs before the first hard freeze.
