The Real Cost of DIY Septic Installs (And Why It Pays to Hire Pros)

Published on 24 June 2025 at 12:24

If you live in rural Alberta, installing a septic system is not just a home upgrade — it’s a necessity. And like most major projects on your property, you might be tempted to take the do-it-yourself route.

You’ve seen the YouTube videos. You’ve borrowed your cousin’s backhoe. You’ve got a strong back, a stubborn streak, and a budget to watch. So how hard can it really be?

Here’s the reality: septic systems are not garden sheds. Getting one wrong can cost you tens of thousands of dollars, invite hefty municipal fines, pollute your land, and render your property unsafe or unsellable.

At BIG JOHN Earthworks and Septic, we’ve seen it all, from well-intentioned weekend warriors digging themselves into disaster, to homeowners calling us in a panic after a DIY install went south.

As a certified, family-owned business proudly serving rural Alberta, we specialize in earthworks and septic services that are done right the first time. From foundation excavation to culvert installations, custom septic design, and land clearing, we’ve got the equipment, experience, and know-how to handle your toughest projects, and save you money in the long run.

Let’s take an honest look at the real cost of DIY septic installs and why bringing in professionals pays off every single time.


The True Costs of Going DIY

You may think you’re saving money by skipping the contractor, but here’s where the expenses start piling up.

1. Permits and Paperwork Confusion

Many homeowners do not realize that Alberta requires permits and strict compliance for any septic installation. The application process includes soil testing, detailed drawings, and health authority approval. If you miss a step, your system may be rejected or shut down.

2. Improper Design

Not all properties are created equal. Soil type, water table depth, drainage capacity, and slope all impact how your system must be built. DIYers often use a one-size-fits-all approach. That leads to failed leach fields, tank overflows, and dangerous contamination.

3. The Equipment You’ll Need to Rent (and Learn to Use)

Unless you own an excavator, laser level, compactor, and septic-safe backfill materials, you’ll need to rent them, and then figure out how to operate everything safely.

Not to mention: one wrong move can collapse a trench or puncture your tank. That turns your DIY project into a liability.

4. Risk of Fines and Re-dos

Unpermitted installs or failed inspections can lead to fines, mandatory removal of the system, and even lawsuits if contamination occurs. If the system isn’t certified and legal, you may also be unable to sell your home.

Why Professional Installers Actually Save You Money

Let’s break this down further.

Time Is Money

Every weekend spent battling trenches and fittings is time you’re not working, relaxing, or spending with family. What you think saves money actually costs more in hours, frustration, and stress.

Mistakes Are Expensive

Using the wrong type of pipe, placing your tank too close to your well, or misjudging drain field capacity can lead to:

  • Tank backups

  • Saturated soil

  • Groundwater contamination

  • Complete system failure

These issues can result in full excavation and replacement, costing $15,000 to $30,000 or more. A certified pro like BIG JOHN helps you avoid that financial nightmare.

You Only Pay Once

We build septic systems that meet Alberta code, pass inspection the first time, and are tailored to your land’s exact conditions. That means no guesswork, no rework, and no surprises later on.


Common DIY Myths (And the Truth Behind Them)

“I Can Learn Everything I Need on YouTube”

Videos are great for learning to bake sourdough or fix a faucet. Septic systems are a different beast. Your soil conditions, local regulations, and system sizing must be based on professional assessment, not a tutorial filmed in another province.

“It’ll Cost Too Much to Hire Pros”

Factor in equipment rental, gravel delivery, backfill materials, permits, inspections, your time, and the risk of redoing it all. The cost of going DIY adds up fast. With BIG JOHN, you get one price, one contract, and a guarantee.

“If I Do It Myself, I Know It’ll Be Done Right”

Confidence is great, but experience is better. Our team installs systems all year long, across Alberta’s toughest terrain. We know the difference between a good idea and a costly mistake.
