Sedalia homes and their sewer lines

Sedalia's older houses date from its railroad and ranching years in the late 1800s and early 1900s. Newer homes and small acreages spread out along the county roads around town.

The Sedalia Water and Sanitation District supplies water to roughly 94 customers, but it does not run a sewer system, so homes in and around Sedalia treat wastewater with their own septic systems.

Acreage homes west of town often sit on slopes with long runs of pipe out to the tank and field.

Sedalia drain problems

With no town sewer, a Sedalia backup almost always involves the building drain, the line to the septic tank or the tank itself. Older homes near the creeks sit on damp alluvial ground where cottonwood roots chase leaking joints, and long lines on the acreages west of town can freeze when a cold snap follows a dry, snowless stretch.

What drain work usually costs in Sedalia

JobTypical range
Kitchen or bathroom clog cleared$125–$325
Acreage line out to a Sedalia septic tank$200–$550
Thawing a frozen septic line$200–$600

Root cutting near the creeks$250–$650

Where the two Plum Creeks meet

Sedalia grew where East Plum Creek and West Plum Creek come together and the railroad came up the valley toward Denver. The tracks still cross Highway 67 at the center of town, and the old buildings along Manhart Street and Platte Avenue date from the years when ranchers shipped cattle from here. Just west, Highway 67 climbs into Jarre Canyon toward Deckers, and the acreage homes along that road and the county roads around town make up most of Sedalia's housing today.

A water district with no sewer

The Sedalia Water and Sanitation District was formed in 1958 to take over the water system the railroad had built. Despite its name, it supplies water only. There is no Sedalia sewer plant, so every home in the area treats its wastewater on its own lot. That simplifies one thing: when a Sedalia house backs up, the problem is somewhere between the fixtures and the drain field, all of it on your property.

Telling a line clog from a full tank

The first question on a Sedalia septic call is when the tank was last pumped. If it has been several years, pumping is usually the right first step, and the pumper can tell you whether the inlet was blocked. If the tank was pumped recently and the house still backs up, the clog is in the building drain or the line to the tank. A plumber can clear that from a cleanout and push a camera down to the tank inlet to see whether roots, a sag or a broken baffle caused it.

Creekside roots

The older houses near the creeks sit among big plains cottonwoods, which grow wherever groundwater is close. Their roots spread wide and are quick to find a leaking joint in a clay or cast iron line to the tank. Root cutting clears the line, and a camera shows whether the joint can be sealed or should be replaced. Planting new trees well away from the septic line and field saves trouble later.

Frozen lines on open ground

Sedalia winters are usually mild by Colorado standards, but cold snaps that arrive after a dry spell with no snow cover can drive frost deep into bare ground. Septic lines that run shallow across a pasture, or under a driveway that gets plowed, are the ones that freeze. A slow trickle of warm water into a cold line can also freeze layer by layer until it blocks. Thawing usually takes a steamer or a jetter with warm water, fed from the cleanout.

Before the plumber arrives in Sedalia

  1. 01

    Stop using water

    Every flush adds to what has to be cleared or pumped.

  2. 02

    Locate the tank lids

    If you know where they are, uncover them or mark them in the snow.

  3. 03

    Check the date of the last pumping

    It helps decide whether to clear the line or pump first.

  4. 04

    Clear a path

    Long gravel drives and gates can slow down a night call.

Sedalia warning signs

  • Every drain in the house slowing together
  • Gurgling from the lowest toilet
  • Sewage odor near the tank or field
  • Bright green, wet grass over the field in dry weather
  • A drain that stops during a hard freeze

Railroad-era homes and new additions

Some of the older houses in town have been added onto several times, and each addition may tie its drains into the original line at a different point. Those junctions are where clogs and offsets tend to show up. If a Sedalia home backs up in one wing but not another, mention it; it tells the plumber which branch to look at first.

What affects the cost in Sedalia

Clearing a single fixture is routine. A long line to the tank, a buried cleanout, frozen pipe or roots near the creeks all add time. Knowing your tank's location and service history before the call keeps the visit short.

Easy habits for a Sedalia septic system

A septic system on an acreage outside Sedalia lasts longer when the household spreads out its water use. Run laundry over several days instead of all on Saturday, fix a running toilet the week it starts, and keep grease, wipes and cat litter out of the drains. If the house has a water softener, ask whether its backwash can be routed away from the tank. These steps cost nothing and keep the line to the tank and the field from being overloaded.

Buying a home near Sedalia

Before buying an older Sedalia property, have the line from the house to the tank scoped and the tank inspected and pumped. A camera run takes less than an hour and shows roots, sags or broken pipe that a quick look would miss. On acreage homes, ask the seller where the tank, cleanout and field are and when they were last serviced; on older ranch houses, nobody may know without digging.

Sedalia drain questions

Does Sedalia have a public sewer?+

No. The Sedalia Water and Sanitation District provides water only, so homes rely on septic systems.

Should I call a plumber or a septic company?+

If the tank was pumped recently and the house still backs up, call a plumber to clear and scope the line. If the tank is full or overdue, start with pumping.

Why do Sedalia lines freeze?+

Lines to the tank are often shallow, and bare, wind-scoured ground lets frost go deeper than usual.
