Tank set on a level bed of compacted rock and checked before any backfill goes in. Once the yard is put back you should never have to think about it again. Comment INFO.

Before the installation comes the preparation. 🚜

A successful septic, sewer, water, or excavation project starts with a properly prepared site.

From grading and aggregate placement to compaction and creating a stable working surface, the details done before the main installation can make all the difference in the finished project.

At CDA Septic Systems, we don't cut corners on the work underneath and behind the scenes. Build it right from the ground up.

Buying acreage up here? Ask this before you fall in love with the kitchen.

Where is the septic system actually located, and is there a permit on record for it?

That's it. That one question has saved people a lot of money — because "there's a septic out there somewhere" and "there's a permitted, located, functioning system" are two very different things when you're the one holding the keys.

Realtors and buyers: we'll walk a property with you before closing.

Would you check the septic before you closed? 👇

Wipes labeled flushable do not break down the way toilet paper does. They collect in the line and in the tank until something backs up. Toilet paper only, everything else goes in the trash. Call 208-290-6888 with questions.

Septic work on lakefront lots, where the tank has to fit on a slope and the yard has to go back the way we found it. Poly tanks set into a cut hillside above the docks, a concrete tank craned in beside a lake house, and a mini excavator working tight between the house and the bank. Steep, narrow, and no room to be careless. Comment INFO or call 208-290-6888.

Pipe bursting pulls a new sewer line through the path of the old one. That means two small access pits instead of a trench across the whole yard. Not every line is a candidate, so we look first. Call 208-290-6888.

A healthy looking lawn tells you nothing about the pipe underneath it. A camera does. If your line keeps backing up, we find the actual cause before anyone starts digging. Comment INFO or call 208-290-6888.
