For Denver-Area Owners
Cesspool Pumping
Many older Denver properties still rely on cesspools instead of modern septic systems. "A company that mostly pumps new tanks won't know what to do with an old pit," owners tell us. We do. Our same 2,600-gallon vacuum truck handles everything from large septic tanks to cesspools in one trip — and when a pit stops draining, we add high-pressure jetting and a camera inspection to clear blockages and assess the structure. Serving Denver and the surrounding area, we follow CO-licensed disposal protocols whether pumping a cesspool or helping you schedule a home pump-out elsewhere on your property. For maintenance tips, the Colorado health department resources outline safe practices, but Denver cesspool owners can call us directly for service.

Know What You Have
How a Cesspool Differs
Know the difference. A cesspool is a single, older pit that lets liquid waste seep directly into the soil through its porous walls—unlike a modern septic system, which splits the work across two distinct parts, specifically the tank and a separate leach field. You can learn more about these older systems through the national onsite wastewater recycling association. Adherence to state disposal rules is required in Colorado regardless of the setup. Reach out to our septic pumping service at (303) 653-1001.
A cesspool
A cesspool functions as one porous pit for all waste. Solids settle at the bottom, while liquid seeps through the walls directly into the soil. There is no separate drain field; the ground surrounding the pit handles the final disposal.
A modern septic system
A Septic Tank holds and separates waste, keeping solids contained. Then, treated liquid flows into the leach field for natural filtration. Our team in Denver, CO manages the tank side, ensuring your system remains functional and clean for years.
Cesspools lack a leach field to protect, so maintenance focuses entirely on the pit. We drain the full volume and clean the walls to ensure the surrounding soil continues to accept liquid flow. Proper servicing prevents yard flooding and keeps your system functional. Draining and jetting steps follow below.
Our Process
Draining and Inspection in Denver
A slow cesspool or active backup signals that the lines and the soil around the pit have stopped taking flow entirely. When a cesspool drains slowly or backs up, the soil stopped taking flow, so our Denver crew drains the pit, clears the lines—and runs a camera inside to determine exactly when a tank is due rather than guessing. Camera work matches. We use the same camera work on tanks.
-
1
Drain the pit
Our vacuum truck draws the entire pit down, pulling solids and liquid together until the tank is empty. We do not just skim.
-
2
Jet the lateral lines
High-pressure jetting scours the lateral lines feeding the pit, breaking up the buildup that keeps liquid from seeping away.
-
3
Camera-inspect the lines
A high-resolution video pipe camera runs the drain and sewer lines to pinpoint the exact blockage or break. You get the real reason instead of guessing.

Catch It Early
Signs of a Failing Pit
A cesspool warns you before failure—when the soil stops absorbing, waste backs up into the yard or house. Slow drains, foul odors, or soggy patches mean trouble. For Denver homeowners, these signs demand action. Call (303) 653-1001 before a small issue becomes a costly mess.
-
Yard flooding over the pit
Soggy ground or pooling water directly over the cesspool means liquid has nowhere left to seep.
-
Backups inside the house
Slow drains, gurgling toilets, or waste backing up at your lowest fixtures point straight at the pit.
-
Standing water and odor
A persistent wet spot or sewage smell over the pit means your tank is at capacity and needs pumping.
-
Bright, fast-growing grass
Unusually lush grass over the septic pit indicates leaking effluent and a failing system that requires professional [Septic Tank Pumping] service.
Catch it early. A prompt pump-out and jetting buy an aging pit extra years, but delayed action pushes backups inside the house. Those same warning signs appear on every setup, so you must track what a full tank looks like before solids block the outlet pipe—cause a yard flood—or force an emergency dispatch that costs twice as much.
Denver Cesspool Owners
What Owners of Older Systems Say
"Other companies only handled modern tanks, but this crew pumped my 1950s cesspool and jetted the lines. The yard finally stopped flooding after they finished."
"Had a backup last week and called Septic Tank Pumping. The crew found the clog fast with their camera, showed me the exact spot, and stuck to the price they quoted. No surprises—just solid work."
"The crew kept the truck on my driveway and only ran the hose across the grass. They even left a written record of the pumping for my files. Very efficient."
Common Questions
Cesspool Pumping Questions
Can you actually pump an old cesspool, not just a modern septic tank?
"Can you even pump old cesspools?" Yes. In Denver, we service them regularly—using the same heavy vacuum truck and rigid suction hose as for septic tanks, and when the pit stops draining, we add high-pressure jetting to clear lateral lines, run a camera to inspect interior walls, and if needed, coordinate with storage tank pump-outs. Short answer: we handle it.
Will an old system cost more, with surprise fees at the lid?
Standard pumping for a typical residential tank in Denver, CO typically runs between $350-$550. This covers the removal of sludge and scum layers. For extra work like jetting a clogged line, expect to add $150-$300. We provide a full septic pumping cost breakdown before we start. Any additional labor or digging is quoted upfront so the final invoice matches your estimate.
My pit isn’t draining — can pumping alone fix that?
Pumping alone might temporarily clear a slow pit, but clogs in the lateral lines often cause the drainage issue. We recommend jetting those lines to reopen seepage paths and using a video camera to find breaks. During our interior baffle inspection, we provide a real diagnosis instead of a quick fix that fails next week.
Where does the waste go — is your disposal legal?
We haul every load to a permitted disposal facility following all Colorado regulations. Each job includes a waste manifest to track the discharge. Homeowners cannot legally dispose of cesspool waste themselves, which is why you need a licensed truck and proper permitting to ensure everything stays compliant.
