New tank, new field, one permit
Greeley Quality Septic Septic System Replacement in Greeley
When both the tank and the field are past saving, the whole system is replaced to today's Colorado and county standards.
- Greeley and nine towns within 20 miles
- Written price before any digging
- Licensed, insured local contractors
- Weld and Larimer County rules covered
Greeley Quality Septic arranges full septic system replacements around Greeley, for houses where the tank, the field or both have reached the end. A replacement is designed from scratch to the current rules, which usually means a bigger, two-compartment tank and a field sized to the bedrooms and the soil, so the new system often looks nothing like the one it replaces.
Pumping a tired system every few months while it fails can cost $475 to $800 a visit with nothing to show for it; the $28,000 to $35,000 replacement is coming either way, and it is cheaper to plan than to rush.
$28,000 to $35,000 for a three to five bedroom house
A complete septic system replacement around Greeley typically runs $28,000 to $35,000 for a three to five bedroom house, the range a Northern Colorado septic installer publishes. The leach field alone is usually $22,000 to $29,000 of that and a new tank $9,500 to $11,500. Add the county permit, $1,100 for a repair in Weld and $1,320 in Larimer in 2026, and an engineer where the site needs one.

- The tank is cracked, collapsing, or made of steel that has rusted through
- The field has failed and the tank is undersized for the bedrooms in the house
- The system predates any permit on file and nobody knows how it was built
- Repairs keep coming back within a year or two
- The house is being enlarged or a bedroom is being added
What a replacement must meet
A replacement is built to Colorado's septic rule, Regulation 43, as adopted by the county. Tanks are sized by bedrooms: at least 1,000 gallons for two or three bedrooms, 1,250 for four, and 250 more for each bedroom after that. Larimer County's regulation also requires a new tank to have two compartments, or two tanks in series, with the first holding at least half the volume.
The field is sized from the soil. A soils evaluation sets the long-term acceptance rate, how many gallons a day each square foot of soil can take, and the design works backward from the house's design flow. On slow clay loam that produces a much larger field than on sandy loam.
The process
- A site and soils evaluation where the new field will go
- A design document with flow calculations, from a professional engineer where the county requires one
- The county permit, after a site inspection; about five working days in Weld with a complete application
- Abandonment of the old tank. In Weld County that needs a pump receipt from a county-licensed septic tank cleaner and an inspection or approved photos
- The new tank and field installed and inspected before backfilling, and a record drawing filed

Call (970) 442-7072Why replacements cost more here than people expect
The excavation is the visible part. The cost is driven by what the soil allows. Around Berthoud, Loveland and Fort Collins, USDA rates most sampled ground "very limited" for conventional fields because water moves slowly through the clay, so the field is larger or the system is engineered with a pump and pressure distribution. Near the rivers, groundwater within four feet of the surface triggers an engineered design in Weld County on its own.
The permit and the paper also cost real money before anyone digs: soils work, design, and a county fee of over a thousand dollars.
Planning it rather than reacting
The cheapest replacement is the one done in dry weather, with the soils evaluation finished before the old field gives out completely, and without a closing date on top of it. If a septic inspection or a pumper has warned that the field is near the end, getting the test pits dug and the design started buys time to compare quotes.
Selling a house that needs a new system
In Larimer County the transfer inspection will find it, and the buyer and seller have to agree who replaces it. In Weld County a buyer's own inspection usually finds it too. Either way, a soils evaluation and a written quote turn an argument into a number.

How much does it cost to replace a septic system near Greeley?
Typically $28,000 to $35,000 for a three to five bedroom house, plus the county permit and any engineered design.
What size septic tank does Colorado require?
At least 1,000 gallons for two or three bedrooms, 1,250 for four, and 250 more for each extra bedroom.
What are the signs a septic system needs full replacement?
A failed field with an undersized or deteriorating tank, repeated repairs that do not hold, or a system with no permit record.
Does the old septic tank have to be removed?
It has to be properly abandoned. In Weld County that needs a pump receipt from a licensed cleaner and a county inspection or approved photos.
Will a new system be bigger than the old one?
Often. Today's rules size the tank by bedrooms and the field by the soil, and older systems were frequently built smaller.
Often done together
-
Leach field replacement
When a field has stopped taking water, the fix is a new one, sized and designed for the soil on your lot.
-
Septic tank replacement
If the leach field is sound and the tank is not, the tank can be replaced on its own.
-
Engineered septic systems
Pressure-dosed fields, pump tanks and treatment units, designed and stamped by a professional engineer for the lots where a simple gravity field will not work.
Talk it through before anyone digs
Say what the house is doing, how old the system is and when the tank was last pumped. You will hear what the job usually involves, what it tends to cost, and whether it needs digging at all.
