Sewage backup is contaminated water and is not handled like a clean-water flood. Keep people and pets out of the area, and before you assume the blockage is yours, check with the city — the order of those two calls can save you a plumbing bill.

What should I do after a sewage backup in Anoka?
If every drain in the house is backing up, call the City of Anoka at 763-576-2923 during business hours or 763-576-2860 after hours through Anoka-Champlin Fire dispatch before assuming the blockage is yours. The City says it will work with the resident to identify the cause. If only one floor drain or fixture is affected, the blockage is more likely in the private lateral. Keep people out of contaminated water, protect yourself, document damage, and start cleanup promptly. City of Anoka Sanitary Sewer Information

First actions after a sewage backup
- If all drains are involved, call 763-576-2923 in business hours or 763-576-2860 after hours before treating it as a private blockage. City of Anoka Sanitary Sewer Information
- Leave immediately and call 911 for immediate danger, such as a suspected gas leak, fire, or an electrically charged flooded area. CDC reentry guidance
- Wear rubber boots, rubber gloves, and goggles when sewage cleanup is unavoidable. CDC cleanup guidance
- Keep hands away from your face, wash with soap and water after handling waste, and wash contaminated clothes in hot water with detergent. CDC cleanup guidance
- Photograph damage before disposal, then remove wet porous materials that cannot be cleaned and dried within 24–48 hours. FEMA claim guidance · HUD flood-cleanup fact sheet
- On cleanable hard surfaces affected by overland flooding or sewage, MDH advises a diluted bleach solution of 1/4 to 1/2 cup per gallon, left for at least 30 minutes before wiping and drying. Minnesota Department of Health
What does “private lateral” mean after a backup?
The private lateral is the portion of the sewer connection serving an individual property rather than the city main. A backup limited to one floor drain or fixture points more toward that private side; an all-drains backup is the situation where the City asks residents to call first. City of Anoka Sanitary Sewer Information
Why is sewage cleanup different from clean-water cleanup?
Sewage-contaminated water can expose people to bacteria and illness risks, including wound infections, rashes, and gastrointestinal illness. Porous items soaked by floodwater generally cannot be reliably decontaminated, while materials that do not absorb water can usually be cleaned and dried.

Common questions after a sewage backup
Should I call the City if every drain is backing up?
Yes. The City of Anoka directs residents experiencing a backup affecting all home drains, or a no-water situation, to call first. Use 763-576-2923 during business hours and 763-576-2860 after hours through Anoka-Champlin Fire dispatch. The City says it will work with the resident to identify the cause and will attempt to clear a blockage in a city main sewer line. City of Anoka Sanitary Sewer Information
What if only one basement floor drain is backing up?
A single affected floor drain or fixture is different from every drain in the home backing up. Limit use of that plumbing and treat the private lateral or fixture as the more likely place to investigate. Do not wade into water around outlets, cords, or wet electrical equipment; standing water can be electrically charged. National Weather Service flood guidance
What protective gear should I use around sewage?
For sewage cleanup, CDC advises rubber boots, rubber gloves, and goggles. For handling human waste, CDC also lists a protective face mask or splash-proof face shield, liquid-repellent coveralls, waterproof gloves, and rubber boots. Wash hands with soap and water immediately after handling waste, before eating, and after using the toilet. CDC cleanup guidance
What must be thrown away after sewage gets into a basement?
Wet materials from flood or sewage water that cannot be thoroughly cleaned and dried within 24–48 hours should be discarded because they can remain a source of microbial growth. Porous items soaked by floodwater generally cannot be reliably decontaminated. Photograph damaged items before disposal when safe, especially if you may make an insurance claim. HUD flood-cleanup fact sheet · FEMA claim guidance
Can I disinfect hard surfaces after a sewage backup?
MDH advises that when water damage or mold growth is due to sewage backup or overland flooding, use a diluted bleach solution of 1/4 to 1/2 cup of bleach per gallon of water. Apply it, leave it for at least 30 minutes, then wipe and dry. Wear appropriate protection and do not treat porous, sewage-soaked material as reliably cleanable. Minnesota Department of Health · EPA flood-cleanup guidance
How quickly do I need to remove wet materials?
Start immediately once it is safe. EPA and HUD guidance emphasizes drying wet areas and items within 24–48 hours to reduce mold risk; sewage or flood contamination also changes the disposal decision for porous materials. This is why a sewage backup needs both source control and a careful separation of hard, cleanable surfaces from contaminated absorbent materials. EPA mold and moisture guide · HUD flood-cleanup fact sheet

Call the city first, then call us
The City of Anoka asks residents to report sewer backups so Public Works can check the municipal main: 763-576-2923 during business hours, 763-576-2860 after hours.
If every drain is affected
The obstruction may be in the city main. Call Public Works first at the numbers above and let them clear or rule it out.
If it is one floor drain or fixture
The blockage is likely in your private lateral or an interior line. That is a plumber, then cleanup.
Either way
Stop using water in the house — every flush and every load of laundry adds to what is coming back up.
Confirm current contact numbers and procedure with the City of Anoka before publishing; municipal numbers change.
Why contaminated water is different
Restoration standards classify water by contamination. Clean water from a supply line is Category 1. Water that has picked up contaminants — a washing machine discharge, for example — is Category 2. Sewage is Category 3: it carries pathogens, and the assumption is that porous materials it touched cannot be cleaned back to safe.
- Porous materials that absorbed it — carpet, pad, batt insulation, particleboard, affected drywall — are removed rather than dried.
- The work area is contained and negative air is used so contamination is not spread through the rest of the house.
- Hard surfaces are cleaned and then sanitized, not just wiped and dried.
- Drying happens after removal and cleaning, never instead of it.
Coverage for sewer backup is commonly a separate endorsement rather than part of a standard policy. Check yours, and see insurance water damage claims in Minnesota.
The Anoka two-step: verify, then fix
Step 1: Call the City. If the backup affects all of your drains, call City of Anoka Public Works at 763-576-2923 during business hours or 763-576-2860 after hours and have them check the municipal sewer main.
Step 2: If the city clears the main and your basement is still flooded, the blockage is in your private lateral line. Call us immediately, and call a plumber to clear the line — cleanup and sanitizing follow the repair, because clearing the blockage without removing the contaminated material only ends half the problem.

Asked and answered
Direct answersWho do I call first for a sewage backup in Anoka?
Call the City of Anoka Public Works first if every drain in the building is affected, because the blockage may be in the municipal main: 763-576-2923 during business hours, 763-576-2860 after hours. If only one floor drain or fixture is backing up, the obstruction is likely in your private lateral and cleanup follows the plumbing repair.
Why is sewage cleanup different from a clean-water flood?
Sewage is Category 3 water and carries pathogens. Porous materials it contacted — carpet, pad, batt insulation, particleboard, affected drywall — are removed rather than dried. The work area is contained with negative air so contamination is not spread, hard surfaces are cleaned and then sanitized, and drying happens after removal, never instead of it.
Is sewage backup covered by insurance?
Sewer and drain backup is commonly excluded from a standard homeowners policy unless you carry a specific backup endorsement. Check your declarations page and open the claim promptly. Documentation of the affected area and the materials removed is what supports the claim either way.
