Windsor, halfway to Fort Collins
Greeley Quality Septic Septic Service in Windsor, CO
A town in two counties, where the parcel line decides which septic rules apply.
- 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 Windsor with local septic crews for pumping, inspections, repairs and replacement systems. Windsor has grown to about 41,700 people, and it sits in both Weld and Larimer counties, so the first question on any septic job here is which county the parcel is in. The answer changes the permit fee and whether a house sale needs an inspection.
A pump-out every few years costs $475 to $800 in Windsor; skip it until solids reach a slow clay field and the fix is a $22,000 to $29,000 replacement with a county permit and soils work.
$475 to $800 to pump a tank up to 1,000 gallons

Two counties, two sets of rules
Most of Windsor is in Weld County, and the western part is in Larimer. On the Weld side, septic permits come from Greeley, a repair permit is $1,100 in 2026, and there is no inspection requirement when a house is sold. On the Larimer side, a major repair permit is $1,320, a new system $1,881, and the county's Transfer of Title program requires a septic inspection and a county Acceptance Document before a sale closes.
The county is on the property record. Check it before booking an inspection for a sale, because on the Weld side the inspection is a recommendation, and on the Larimer side it is a requirement with a 12-month window.
Soils that change across town
A 25-point USDA sample around Windsor came back split: 8 points rated "not limited" for a conventional septic field, 9 "somewhat limited" and 7 "very limited". Slow water movement was the leading reason on 15 points, with flooding and a shallow saturated zone near the Cache la Poudre. The soils run from Kim and Ascalon loams on the uplands to Otero sandy loams and wet Aquolls on the river ground.
In practice, systems on the higher ground north of town often work as gravity fields, and those on lower or tighter ground more often need an engineered system.

Call (970) 442-7072The Poudre and the ditches
The Cache la Poudre runs along the south side of Windsor on its way to Greeley, and the town grew up on irrigated wheat and sugar beet ground fed by ditches off the river. Those ditches still cross acreage all around town, and a soil treatment area must sit at least 50 feet from an irrigation ditch under Weld County's setbacks. On a lot with a ditch on one side and a well on the other, that decides where a replacement field can go.
How many systems there are
Weld County's permit map shows about 500 distinct septic permits within three miles of the middle of Windsor and about 1,100 within five, and that counts only the Weld side. Larimer County publishes no comparable count, so the real number around town is higher.
Selling a house in Windsor
Check the parcel's county first. Larimer-side sales need a transfer inspection and an Acceptance Document; Weld-side sales do not, though buyers usually want one.
Call (970) 442-7072A town built on wheat and sugar
Windsor started as a halfway house between Greeley and Fort Collins in 1873, was platted in 1882 and incorporated in 1890. A sugar beet factory opened in 1903, and families of Germans from Russia came to work the beet fields. The farmhouses from that era that still stand on acreage outside town are exactly the ones with old septic systems and no records.
