The job itself
How septic service is done properly
Septic System Services is handled by independent licensed professionals across Colorado. This page covers what the work involves, what changes the price, and the Colorado code and permit rules that apply — then links to the 37 largest markets where a local page exists.
- Tank is located, uncovered and sludge and scum layers are measured
- Baffles, filter and lid condition are inspected
- Tank is pumped and the effluent filter cleaned or replaced
- The drain field is assessed for ponding or failure
- Pumping interval is set from household size and tank volume
Scope boundary
What a standard visit covers — and what is billed on top
The single biggest source of quote disputes is the boundary between these two columns. Get it written down before work starts.
| Normally included | Commonly billed on top |
|---|---|
| Visual inspection of baffles, effluent filter and inlet condition | Drain field evaluation, jetting the laterals or engineering a replacement field |
| Locating and opening the tank access lids at grade | Excavating buried lids and installing risers for future access |
| Measuring sludge and scum layers before pumping the tank | Replacing a broken baffle, effluent filter, lid or tank riser |
Price drivers
What drives septic pricing in Colorado
- 01
Tank size and how long since the last pump-out
- 02
Access — whether the lid is at grade or must be excavated
- 03
Whether the effluent filter, baffles or lid need replacing
- 04
Distance the pumper must travel and local disposal fees
- 05
Whether the drain field has failed, which is a different scale of job
Before you sign
Questions to ask before authorising septic service
- 01
Does the pumper hold the state septic hauler permit, and where is the waste manifested for legal disposal?
- 02
What signs of drain field failure were observed, because ponding or lush growth over the field changes the entire plan?
- 03
How many gallons does the tank hold, and what pumping interval suits the household size and the current sludge depth?
- 04
Are the lids at grade, or must the tank be located and excavated before pumping can begin?

Before anyone touches a pipe
Verify the licence. It takes two minutes.
- Who licenses the work: State Plumbing Board, Colorado Division of Professions and Occupations (DORA) together with the local jurisdiction.
- Who pulls the permit: the licensed contractor, never the homeowner.
- What to ask for: the licence number, the registered name behind it, and an insurance certificate issued to the property address.
Answers first
Septic in Colorado — frequently asked
How often does a septic tank need pumping?
For most households, every 3–5 years, but it is driven by tank volume and occupancy rather than the calendar. A household of five on a small tank may need it more often than a couple on a large one.
What must never go into a septic system?
Wipes of any kind including 'flushable' ones, grease, paint, solvents, harsh drain chemicals and excessive bleach. The system depends on live bacteria — anything that kills them or will not break down shortens the drain field's life.
Is a septic backup an emergency?
Treat sewage entering the building as urgent for health reasons. Stop using water in the house immediately, since every gallon added makes it worse, and get a licensed pumper or plumber out.
Who handles the permit for septic in Colorado?
The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the licence.
What warranty applies to the work?
Whatever the contractor offers in writing — PlumberColorado is not a party to the agreement. Ask for labour and parts warranty terms in the quote, and keep the licence number with the paperwork.
How does the callback request work?
The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.
Which areas does PlumberColorado cover?
All of Colorado: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
Is PlumberColorado a plumbing company?
No. Independent licensed professionals perform and contract the work directly with you. PlumberColorado routes the request and links every page to the official Colorado licence register.
