Commercial Septic Pumping in Colorado

A blocked tank does not wait for a slow traffic week. When a commercial system backs up, the wastewater goes nowhere but back into your building. A-1 Septic Service has serviced business septic systems since 1976. We help determine how much traffic your system is actually getting and put you on a schedule so that you don't end up in an emergency situation.

Why Businesses Choose A-1 Septic Service

A-1 Septic Service has been family-owned and operated, proudly serving Colorado since 1976. What keeps a commercial customer is rarely the pump-out itself. It is what happens around it.

Always Honest

We do our best to put you on a schedule that's right for your business. If we get out to your site and don't need to be pumped, you'll be charged for a service call, not for a pump out you really didn't need.

No Emergency Surcharges

Because we're a small business, we are able to take calls around the clock (the phone literally sits on our kitchen counter). Emergencies happen and you shouldn't have to pay more for them.

Same Small Team

Our family owned company actually cares about your business. Your call will always be answered by the same friendly voice and your service will always be by the same two drivers. You don't have to re-train a new driver of your property every time we are out for service.

Licensed, Certified & Insured

In order to pump or inspect septic systems in Colorado, you must be licensed in each county you wish to work in. We are licensed in Adams, Arapahoe, Boulder, Broomfield, Larimer and Weld. We also are NAWT certified and hold appropriate insurances.

Great guys and company to work with. We had plumbing issues at our house and knowing that our septic tanks were near end of life and would not pass a future inspection we decided to do get the the issue fixed and the tanks replaced at the same time. Travis and Neil did a great job in the replacement. Venessa kept us informed along the way and was there for all our questions. Thank you Spencer for such a great company, and I look forward to a long relationship.

Vanessa was the only company I called that answered the phone. Everyone else was “leave a message”. She was thorough in explaining cost breakdown and scheduled me. Spencer was so pleasant and answered all my questions, cleaned the tanks thoroughly, was careful to not drive on the leech field, explained the inspection. Highly recommend this company. 🌟 🌟🌟🌟🌟

I have used this company for years. Recently had them out and they were honest with me that the tank didn’t need to be pumped and that I could wait another year. This company is professional, punctual and honest. I would definitely refer their services!

Spenser and Vanessa are amazing to work with. They were great at communicating the processes, and provided really candid information about the condition of our septic tank. While the results of our tank pump-out and inspection weren't great (40+ years of not being pumped is not a good thing), they were honest, kind and affordable. 100% would recommend them for quality septic service.

A-1 Septic is fantastic! They answered my call (a lot of septic service providers do not), scheduling was a breeze, and they showed up on time and provided exceptional service. I’m so glad I found them. A few things to highlight: 1) this is a small, family business and it shows with their communication and care 2) their price always hundreds less than every competitor I called 3) I received confirmationn calls ahead of the appointment, and the day of the appointment letting me know the driver was on his way - nice touch 4) in a “dirty” business, they work very clean. No mess anywhere, no leaks, and went the extra mile to ensure there was no disruption to my yard. Spencer - their owner - couldn’t have been nicer and if you need septic service - you’d be foolish not to work with A-1 Septic!!!

Pumping at Commercial Properties

Guessing at when your business's tank needs to be pumped next can leave you either overpaying or without facilities.

01
Determine the System's Traffic
Commercial systems often see much higher volumes than residential, so the pumping likely needs to be more frequent. We will work with you to determine how often you should be pumping without overpaying or risking an emergency.
02
Locate the Tank & Soil Treatment Area
We will pull any available county records and walk the site to locate all components of your system. Once tank size is determined & pumping frequency is set, we will provide you a quote and get started.
03
Schedule During Slow Business Hours
Our trucks are big and septic can be smelly. We will work with you to determine what time of day or day of the week works best to service your property without disrupting your business.
04
Pump & Report Back
We will pump your tanks and perform a visual inspection of the system. You'll know how much we pumped, if the set schedule is still optimal pump timing and if we see anything that needs to be addressed to keep your system running smoothly.

Common questions

Commercial Septic FAQs

These come up on almost every first commercial visit. Where a rule is involved we have named the source, so you can check it yourself.

Can you pump outside our business hours?

Yes, we will do our best to schedule during a slow time or set up a time outside of typical business hours so we aren't a disruption.

What service records should we keep for a health inspector?

The EPA tells owners to keep maintenance records for all work performed. It also says the provider should note tank condition and any repairs. Counties can issue an operating permit for maintenance and inspections at regular intervals, and those reports are the evidence.

Please visit your county site to learn more about record requirements or to talk directly with your county officials: Adams, Arapahoe, Boulder, Broomfield, Larimer or Weld.

What happens if the septic system stops performing or starts backing up during business hours?

We answer emergency calls around the clock and add no fee for the service. As much as possible, limit water use until we can get there. We will pump the tank and help determine the cause of the emergency.

What is the average pump frequency for a business?

Pump frequency truly depends on your business's foot traffic. For businesses that see heavy foot traffic, we pump monthly or quarterly. For others, they can be pumped annually or every other year.
