Evans, along the South Platte
Greeley Quality Septic Septic Service in Evans, CO

- 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 connects homeowners in and around Evans with local septic crews for pumping, repairs, inspections and replacement systems. Evans sits directly south of Greeley, about 22,400 people by the latest Census estimate, and most of the city is sewered; the septic systems are on the acreages around its edges and on the low ground toward the South Platte River.
Around Evans a field on low river ground can sit in rising water each summer, so skipping a $475 to $800 pump-out and check until it backs up often means a $22,000 to $29,000 engineered replacement instead of a repair.
$475 to $800 to pump; $22,000 to $29,000 for a new field
Pumping a standard tank around Evans typically runs $475 to $800 for a tank up to 1,000 gallons. Minor repairs typically run $300 to $800. A new leach field runs about $22,000 to $29,000, and on low ground where groundwater is within four feet of the surface, Weld County requires an engineered design, which adds to that.

- Backups that start when the irrigation ditches run and ease off in the fall
- Water flowing back into the tank from the field as soon as it is pumped
- Soggy ground over the field on a lot near the river or a lateral ditch
- A sewage smell in the yard after a heavy storm
- A basement or crawl space that takes on water in the same months
River ground and a seasonal water table
Evans grew along the South Platte, and much of the land around it is river terrace and bottomland. USDA soil ratings sampled at 25 points around the city split three ways: 11 points rated "not limited" for a conventional septic field, 7 "somewhat limited" and 7 "very limited". The most common reason was slow water movement, followed by flooding, a shallow saturated zone and seepage in the bottom layer, in soils such as Olney and Vona loams on the higher ground and wet Aquolls near the river.
Those are ratings for conventional gravity trenches, not a verdict on any lot. They explain why two neighbors in Evans can have very different septic systems: one a plain gravity field on a sandy terrace, the other an engineered system on low ground a quarter mile closer to the river.
Weld County rules apply
Evans is entirely in Weld County, so septic work here is permitted by the Weld County Department of Public Health and Environment in Greeley. A replacement field needs a $1,100 repair permit under the 2026 fee schedule, with a site and soils evaluation and a design, and an engineer's design wherever groundwater or a restrictive layer is within four feet of the surface.
There is no inspection requirement when a house in Evans is sold. Weld County recommends one and a pump-out by a licensed cleaner anyway, and a buyer looking at a house on river ground should ask for a septic inspection before closing.

Call (970) 442-7072How many systems are out there
Weld County's permit map shows about 580 distinct septic permits within three miles of the middle of Evans and about 1,300 within five, mostly on the city's edges and the unincorporated land toward La Salle and Kersey.
Some history worth knowing
Evans was named for John Evans, Colorado's second territorial governor, and was the Weld County seat from 1870 until 1877, when the county seat moved to Greeley. The commercial strips along US 85 and 23rd Avenue are sewered. As the city grows west and south of the river, new subdivisions are usually connected to sewer, and older acreages nearby keep their septic systems.
Backup in irrigation season
Cut water use and call. A pump-out tells you whether the tank is full or the field is flooded from below, and that decides everything else.
Call (970) 442-7072Timing work in Evans
The best time to diagnose a field near the river is when it is struggling, usually summer, but the best time to replace one is when the water table is down, in late fall or winter before the ground freezes. Test pits dug in a dry month can miss a seasonal high, so ask whoever does the soils evaluation how they read the soil for signs of past saturation.
