Emergency Septic System Repair Across the Denver Metro

An independent, licensed plumbing contractor. Not affiliated with Denver Water or the City and County of Denver.

A septic emergency is sewage reaching living space, effluent surfacing in a yard where people or animals walk, or a tank lid that has failed or cannot bear weight. Denver Sewer and Water responds to those calls, makes the site safe first, and then diagnoses the cause rather than pumping and leaving.

  • Sewage in living space and surfacing effluent.
  • Failed, cracked, or missing tank lids.
  • Site made safe before diagnosis begins.
  • Locating and excavation available same visit.
  • Call (720) 935-6221 for an emergency.

What Counts as a Septic Emergency?

Three situations warrant an immediate call. Wastewater rising into a tub, a shower pan, or a floor drain means the system has no capacity left and every fixture used makes it worse. Effluent surfacing over the tank or field means untreated wastewater is at ground level where it should never be. A tank lid that is cracked, flexing, or missing means there is an open void in the ground.

Everything else can usually wait for a scheduled visit. Slow drains, mild odour, and a pumping interval that is shortening are all real problems, but they are problems you can book rather than problems that need a truck tonight.

Call immediately if you see

  • Sewage in a tub, shower, toilet, or floor drain.
  • Standing effluent or wet ground over the tank or field.
  • A cracked, flexing, sunken, or missing tank lid.
  • Strong sewage odour inside the building.
  • A tank lid you cannot account for on a property with children or livestock.

How We Diagnose It

What We Do First on an Emergency Call

Safety comes before diagnosis. If a lid has failed, the opening gets secured before anything else happens. If effluent is surfacing, the area gets marked off. If sewage is indoors, we tell you to stop using water immediately, because every flush adds to what has to be cleaned up.

Once the site is safe we find the cause. Camera the building sewer, open the tank, read the liquid level against the outlet invert. Emergency pumping is often part of the visit, but pumping alone on a system that refilled in days is a temporary measure and we say so rather than letting you think it was a repair.

Emergency visit sequence

  • Secure any open or unstable tank access.
  • Stop water use in the building.
  • Camera the building sewer to the tank.
  • Read tank liquid level and baffle condition.
  • Relieve the immediate backup.
  • Identify and scope the underlying failure.

How an Emergency Septic Call Runs

  1. 1

    Call and triage

    We ask what is happening, where, and whether anyone is at risk. That determines the response, and it determines what you should do before we arrive.

  2. 2

    Make the site safe

    Open access secured, contaminated area marked, water use stopped in the building.

  3. 3

    Relieve and inspect

    Clear the immediate backup, then camera and open the tank to find the cause.

  4. 4

    Scope the permanent fix

    We tell you what actually failed and what the repair is, in writing, before we leave.

What Emergency Septic Work Costs

Emergency response pricing reflects the hour, the access, and what has to happen to make the site safe. We are straight about that on the phone rather than after the fact.

What we do not do is quote a permanent repair over the phone during an emergency. The cause is not known yet at that point, and any number given before the tank is opened is invented.
