Sewage Backup Cleanup
Sewage backup cleanup in Mesa
Sewage in the house is a health problem as well as a water problem. Keep everyone out of the area and call to be connected with an independent contractor who handles contaminated water.

What happens
Why sewage is handled differently
Water from a sewer line carries bacteria and other contaminants, so porous materials it touches, like carpet, pad, the bottom of drywall and some cabinetry, are usually removed rather than dried. Hard surfaces are cleaned and disinfected, then the area is dried and checked before rebuilding.
Workers wear protective suits, gloves, boots and respirators for a reason. If sewage reached a room, keep children and pets out, don't run the HVAC system through it, and wash your hands well if you touched anything.
Where the blockage sits matters for who fixes the pipe. In Mesa, the city looks after the sewer main in the street or alley; the line from the main to the house, including the connection, belongs to the property owner.

Local detail
Mesa sewer lines: who does what
The main is the city's
Mesa is responsible for sewer mains in the street or alley, including cleaning and repair. Sanitary sewer overflows and backups are listed as water emergencies: 480-644-2262.
The lateral is yours
The city's wastewater page puts it plainly: maintaining and cleaning the lateral line falls to the property owner. Most blockages come from things put down drains, or tree roots that get into a joint or crack.

If the plumber finds a main-line problem
When a licensed plumber finds the blockage is in the city main, call Wastewater Collection. The city charges a fee to inspect and asks you to sign a Sewer Blockage Waiver Form.

Grease and wipes
Mesa asks residents to pour fats, oil and grease into a container for the trash, and to bin wipes, which don't break apart in sewer lines.

Questions
Sewage Backup Cleanup: common questions
Is a sewage backup covered by homeowners insurance?
Often only if the policy has a water backup or sewer backup endorsement; many standard policies exclude it otherwise. Check your declarations page or ask your insurer, and photograph everything before cleanup starts.
Can I clean a small backup myself?
A small overflow from a toilet onto tile can sometimes be handled with gloves and disinfectant. Once sewage reaches carpet, drywall or spreads across rooms, a contractor with protective equipment and the right cleaning process is the safer route.
Who clears the blockage?
A plumber or drain cleaner clears blockages in your line. If they find the problem is in the city's main, Mesa's Wastewater Collection team takes over that part.
