The call usually comes before opening: the floor drain in the back hallway is pushing up gray water, the restrooms will not flush, and the smell has reached the front desk. Nothing is broken inside the building. The problem is the one pipe that carries every gallon of wastewater from the property to the public main, and until it flows again, the site cannot reasonably host staff or customers.
Most continuity plans say nothing about that pipe. The sewer inspection Aurora business owners can book through a local plumbing company is where the fix starts, because a camera survey turns an invisible risk into a documented one. This piece treats the building sewer line as a business dependency with an owner, a control and a test date.
Why the sewer line belongs in your business impact analysis
Exposure. A business impact analysis (the exercise of ranking which processes matter most and how long each can be down) normally lists systems people can see: servers, phones, the point-of-sale terminals. The sewer lateral, the private pipe between your building and the street, rarely appears because it is buried and silent until it fails. Failures tend to start slowly: roots finding a joint, a section of older pipe settling, grease and wipes building a partial blockage that holds until a busy morning.
Impact. When the line stops, every fixture in the building stops with it. Restrooms close, kitchens and break rooms cannot run water, and in a clinic, salon or food business the doors may have to close entirely until the line is cleared. An office may manage from home for a day, but receiving, client meetings and on-site equipment wait.
Control. Name the sewer line as an asset in the plan. Give it an owner, usually the facilities lead or the office manager, and record what you know: where the cleanout is, roughly how old the building and the line are, and when it was last inspected. If nobody knows the answer to that last question, that is the finding.
Test. Ask the owner to walk you to the cleanout and show you the shutoff for the main water supply. If that walk takes more than a few minutes of searching, the control is not in place yet.
The slow failure: roots, settling and buildup
Exposure. Mature trees are a feature of many established commercial streets and older neighborhoods around Aurora, and roots go where the water is. Colorado's freeze and thaw cycles move soil over the winter, and older pipe materials can shift at their joints. None of this announces itself. The early signs are small: a slow drain on the ground floor, a gurgle in a toilet when a sink empties, an odor near a floor drain that comes and goes.
Impact. A slow failure is a gift if someone notices it, and a full outage if nobody does. Early signs land with the people least likely to report them: the cleaning crew, the last person out, the ground-floor tenant.
Control. Two things reduce this exposure. First, a reporting path: anyone who notices a slow drain or a recurring odor tells one named person, and that person logs it. Second, a professional inspection. A plumber runs a camera through the line from the cleanout and shows you its condition: roots, sags where water sits, cracks, offset joints, buildup. That recording becomes evidence you can date and file, which is exactly what a continuity program runs on.
Single point of failure: most commercial buildings have one sewer lateral serving every fixture on site, so one blockage closes the whole building. A scheduled camera inspection, followed by cleaning or repair of what it finds, turns that blind dependency into a monitored one.
Test. Ask yourself when the last slow drain was reported, to whom, and what happened next. If you cannot trace a recent example from report to action, the reporting path exists only on paper.
The sudden failure: a backup on a working morning
Exposure. Some sewer events are abrupt. A heavy rain, a partial collapse, or a blockage that finally closes can push wastewater back up through the lowest fixtures in the building, usually floor drains in a basement or the ground-floor restrooms.
Impact. A backup is a sanitation event, not only a plumbing one. The affected area has to be closed off, people kept away, and cleanup handled properly before anyone works there again. Stock and records stored low are at risk. The building may be usable in hours if the line is cleared quickly, or closed for longer if the pipe itself needs repair.
Control. Put an emergency plumber on the contact list before you need one, alongside the landlord, the property manager and your insurer's claims line. Decide in advance who is allowed to authorize an emergency call and up to what level of spending, so the person on site at 7 a.m. is not waiting for approval. Keep records and stock off the floor in any room with a floor drain.
Test. Run a short tabletop exercise (a discussion-based walk-through of a scenario, no equipment needed). The prompt: "The ground-floor restroom is backing up at 7:15 on a Monday. Who gets the first call, who calls the plumber, and who decides whether we open?" Fifteen minutes around a table will show you where the gaps are.
Repair and replacement as a planned disruption
Exposure. If an inspection finds a collapsed section, a badly offset joint or a line that roots have taken over, the fix may be a repair or a full replacement, and some of that work requires excavation. That is a disruption in its own right: access may be affected and plumbing limited during the work.
Impact. The difference between a planned and an unplanned repair is control. Planned, you choose the week, warn staff and customers, and move critical work elsewhere. Unplanned, the line decides for you, often at the worst moment in your trading calendar.
Control. Treat known sewer work like any other planned outage. Ask the plumbing company what the work involves, how long the building will be without full use of its plumbing, and what the site will look like during the job. Then schedule it around your own calendar: away from quarter-end, peak season or a major client visit. Remember that permits and access rules belong to the city, so ask the local building department or let the contractor handle that conversation. Colorado winters can make ground work harder, one more reason to act on findings before January.
Test. For any planned repair, write a one-page outage notice before the work starts: what will be unavailable, for how long, who to contact, and where people should work instead. If you cannot fill in every line, the plan is not ready.
Who owns this, and what evidence to keep
An examiner, an auditor or an insurer reviewing your program will not ask whether you thought about the sewer line. They will ask what you did and when. That means the control needs an owner and the owner needs a file.
The file is short. It should hold the inspection recording or report, the date, the plumber's findings in plain words, and what was done about each one. Add the location of the cleanout, the emergency contact list, and the name of whoever can approve an emergency call. Leased space adds one more step: read the lease or ask the landlord which party is responsible for the lateral, because that answer decides who books the inspection and who pays for repairs. If the terms are unclear, take that question to your own attorney rather than guessing.
A simple way to set the rhythm:
| Timing | Action | Owner |
|---|---|---|
| Do now | Locate the cleanout and main shutoff; add an emergency plumber to the contact list | Facilities lead |
| Before winter | Book a camera inspection for older lines or any line with a history of slow drains | Facilities lead |
| After findings | Schedule cleaning or repair as a planned outage | Facilities lead with operations |
| Annual | Review the file, rerun the backup tabletop, confirm lease responsibilities | Continuity owner |
What matters is that every row has a name and a date somebody can check.
What to do this quarter
- Assign an owner for the building sewer line and have that person locate the cleanout and the main water shutoff, with photos filed in the continuity plan.
- Book a camera inspection if the line is old, if trees grow near it, or if anyone has reported slow drains or odors in the past year, and file the results.
- Run the 7:15 tabletop with the people who open the building, and update the contact list and approval limits based on what you learn.
The sewer line will never appear on a dashboard, so put it on a calendar instead.
