What failing systems look like around Milliken

  • One end of the field wet while the rest is dry
  • Water returning to the tank from the field after pumping
  • Backups that follow wet springs or irrigation
  • Slow drains across the house on an older system
  • A pump alarm on a system with a pump tank

Mixed ground, mostly slow

Milliken's soils are a patchwork. In a 25-point USDA sample around the town, only 6 points rated "not limited" for a conventional septic field, 11 rated "somewhat limited" and 8 "very limited". Slow water movement came up on 15 of the 25 points, ahead of flooding, a shallow saturated zone and seepage. The soils range from Wiley and Colby silt loams on the uplands to wet Aquolls and Julesburg sandy loams on lower ground.

Slow soil means a field needs more area, and it leaves less margin when one line is overloaded. That is why the distribution box and an even split of flow matter so much here, and why a failing line is worth catching early with a leach field repair.

The Big Thompson and the low ground

The Big Thompson River runs just south of Milliken on its way to the South Platte, and the Little Thompson joins it to the west near Johnstown. Low ground along both carries flooding and a seasonal water table, and Weld County requires an engineered design wherever groundwater is within four feet of the surface. Irrigation ditches cross the farm ground too, and a soil treatment area must sit at least 50 feet from one.

Systems around town

Weld County's permit map shows about 200 distinct septic permits within three miles of the middle of Milliken and about 640 within five. That is fewer than around Greeley or Severance, because more of the land here is still farmed, but it means the acreages that do exist are spread out and often a long way from the next contractor's truck.

Town history

Milliken was named for Judge John D. Milliken. A trading post on the Denver, Laramie and Northwestern Railroad grew into the town, which was incorporated in 1910 and annexed the nearby settlement of Hillsboro the same year. The town itself is sewered; the septic is outside it.

One part of the yard staying wet

Keep vehicles off it, cut water use and call. A single wet line is the cheapest kind of failing field to fix, if it is caught before the others follow.
