The most humbling part about owning a business is knowing your success is based off of people choosing you.

Every project booked is a reminder that someone saw your business and thought "that's where I'll spend my money."

This one's on the lake. Thank you for choosing us.

Lake lot with a septic, sewer or water job that needs doing right the first time? Comment SEPTIC and we'll come walk it with you.

Setting tanks is the part of a septic job you only get one shot at. These show plastic and concrete tanks going into open excavation, bedded and lined up before anything gets covered. Risers and lids get set so the system can be pumped and serviced later. Free estimate at the link below.

No city water out here? Then water storage isn't optional.

A cistern is how you get pressure and volume at the house — sized to what the place actually uses, not to whatever fits on the truck. We install and service cisterns, pumps and water lines across North Idaho.

Working to outrun the night. 🌅🚜

When the job needs to get done, we keep moving. Sometimes that means putting in a few extra hours and working until the last light fades.

This North Idaho excavation and septic project is another reminder that quality work doesn’t always happen during perfect conditions or convenient hours.

From septic system installation and excavation to drainfield work, sewer, and water solutions, CDA Septic Systems is ready to put in the work and get the job done right.

Excavation and site work on ground that does not cooperate. A steep hillside above a neighborhood street with a gravel pad cut in and form tubes set for footings, a fenced open trench running a large black line through a finished yard, and machines working a wooded lot and an open lot. Access and grade get worked out before the first bucket comes up. Free estimate at the link below.

Digging is only part of the job. Backfill, compaction and final grade are what the property looks like when we pull off it. Call 208-290-6888.

Throwback to a cold one! 🥶❄️

The temperatures may drop, but the work doesn’t stop. This throwback is a reminder that North Idaho winters won’t keep us off the jobsite. From septic installation and excavation to water and sewer projects, we’re prepared to get the job done in challenging conditions.

And if this heat has you thinking winter is a long way away… it’ll be back before you know it. 😅

When winter hits North Idaho, you want a contractor who knows how to work with the conditions—not around them.
