Water and Sewer
The City of Northville owns and maintains its own water and sewer
systems. Water is purchased from Detroit as is the case in most
Metro Detroit communities. The City’s sanitary sewer system empties
into a major Wayne County transmission line which takes sanitary
waste to the Detroit Wastewater Treatment Plant.

Sewer Overflow or Backup Information
A sewer back up can be very frustrating and stressful and it is never
pleasant to deal with. Although the City of Northville makes every
effort to prevent such incidents, they still may occur. While sewer
backups may occur for a number of reasons, they are usually caused by
internal plumbing problems in the home or private line (sewer lateral –
the line that runs from the home to the street), and in rare cases, the
public sewer line. If you experience a sewer back up, the situation must
be dealt with in a very careful manner. If not handled properly, health
and safety problems can occur, as well as significant property loss.
First Steps if a Sewer Backup Occurs
- If you discover an overflow or sanitary sewer backup in your
home, which does not appear related to an internal plumbing problem,
immediately contact the City of Northville Department of Public
Works (DPW) at (248) 449-9930 between 8:00 AM and 3:30 PM on
weekdays. After business hours, during weekends or on holidays call
Northville Community Dispatch non-emergency at (248) 349-1234.
- A DPW maintenance crew will be dispatched to your address to
determine if the blockage is in the City main line or your private
line (sewer lateral). If a blockage is found in the city sewer, DPW
will perform any cleaning or repair to that line. This work will be
done as soon as possible and you will be kept informed about what is
- If the sewer main is found to be clear, it is the responsibility
of the property owner to call a licensed plumber or drain service to
correct the problem. The City of Northville and its employees cannot
recommend any plumber. Check your Yellow pages, Business White
Pages, or www.yellowpages.com. You may want to get more than one
estimate from reputable plumbers and check their references. The
City does not have the legal authority or obligation to repair a
private sewer lead.
Cleaning Up After Floods/Sewer Back Ups
Sewer backup can lead to disease, destruction of your valuables,
damage to your house, and the risk of electrocution. Proper responses to
sewer backups can greatly minimize losses from negative health effects
and property damage. Every backup is unique and will require different
responses but there are some universal principles that can be applied to
all situations. Prompt cleanup of affected property can help minimize
the inconvenience and damage.
Health and Safety Issues Please be aware and keep in mind the risk of
potential health and safety problems when addressing the cleanup of your
home. Sewage and floodwaters contain bacteria, fecal material, viruses
and other hazardous microorganisms, which can cause disease. These
“germs” can be transmitted by touching contaminated items or by tracking
them into uncontaminated areas on shoes. Children and pets are
especially vulnerable. Odors from sewage backups are unpleasant but not
harmful. The speedy removal and cleanup of sewer water is very important
To protect yourself and your family during cleanup, please follow
- Avoid skin contact with sewer water, especially cuts and
sores. Keep them clean and covered.
- If you should suffer a cut while working in flood or sewer
water, contact your physician or the Health Department about
receiving a tetanus shot.
- Do not allow children to play in areas contaminated by sewage
- Do not eat or drink anything exposed to sewer water.
- Keep contaminated objects, water, and hands away from mucous
membranes (mouth, eyes, and nose).
- Wash hands frequently, especially after bathroom use, before
eating, and immediately following contact with sewer water or
- Disinfect all areas and equipment that came into floodwater
contact with a solution of 8 tablespoons of liquid chlorine bleach
to a gallon of water. This is a very effective method of removing
odors and bacteria. Bleach solutions are the most effective
disinfectants, but may cause discoloration of many materials.
Do not mix chlorine bleach with
This combination produces poisonous gas!
The Do’s and Dont's of Clean-up - Because of the
unsanitary nature of a sewer backup in the home, it is essential that
all affected areas where the backup occurred be cleaned and disinfected
as soon as possible. Generally, small household items that are affected
or exposed to the sewage should be discarded. It is important to make a
list of discarded items, and if possible, provide photographs for
All affected appliances should be inspected prior to putting them
back into operation. Many private companies can handle the cleanup for
you. Check the yellow pages under the listing “Fire and Water Damage
Restoration" or under
Some companies will also inspect and repair major appliances (furnaces,
water heaters, washers and dryers). If a private company is contracted
to do cleaning and/or restoration, be sure to keep all receipts for
insurance purposes. The City recommends that you immediately arrange for
a thorough, professional, sanitized cleanup of your affected property.
If you choose to cleanup your property yourself, the following
information is provided as a recommendation to assist with your cleanup
- Potential health and safety hazards must be identified and
eliminated prior to implementing cleaning or restoration procedures.
Before entering the affected area the potential for electrical shock
hazards and gas leaks must be assessed.
- The cleanup and drying of the basement should occur as quickly
as possible to minimize mold and risk of problems.
- Wear protective clothing such as rubber boots, gloves and eye
protection during cleanup and removal. To remove gloves turn them
inside out, without touching the contaminated exterior. Dispose of
- Treat all water soaked surfaces, furnishings and items as
contaminated until properly cleaned & sanitized.
- Do not use any electrical equipment while standing in water.
- Wet-vacuum to remove spillage.
- Operate wet vacuums only when plugged into a ground fault
circuit interrupter or ground fault equipped outlet.
- Remove and discard upholstered furniture and porous wood
furniture stained by sewage.
- Discard or properly wash and disinfect toys, clothing and other
- Sanitize and clean hardwood furniture, then thoroughly wipe, dry
and apply and oil-based wood polish.
- Ventilate the affected area with floor fans and a dehumidifier,
if available, to properly dry the area. If it has not been directly
contacted by water, activate the building’s heating, ventilation and
doors when conditions are favorable.
- Clean appliances and/or ductwork. If electric motors, wiring or
insulation have been saturated, have a qualified service technician
remove the motor, dry it, and inspect for damage before plugging it
back in and turning it on.
- Do not use heat to dry closed building interiors; mildew and
expanded water damage may result
- If your basement walls are finished with drywall, all the areas
contacted by water must be removed and disposed of within 24 hours.
Once these items get wet, they retain moisture long enough to grow
mold. Removing the wallboard also allows air to circulate around the
wood studs so that they dry completely and will not need to be
- Sanitize and repair, or remove and discard, paneling, wallboard
or wall coverings.
- Unplug all electrical appliances, small electrical devices on
wet floor covering or other wet areas and turn off the circuit
breakers supplying the electricity to affected areas.
- Turn off the gas (or other fuel source) to your furnace or
heater and hot water heater.
- Avoid flushing toilets or using other water connected to
appliances or fixtures. The discharge from these items may back up
into the basement.
- After the waters have receded, flush out and disinfect plumbing
fixtures before resuming normal use.
- Do not track sewage from the basement into living areas of the
- Keep children and animals out of the affected area.
- Take before-and-after photos.
- If a dishwasher, washing machine, shower, bathtub, toilet or
other water fixture is operating shut it off immediately. Avoid
flushing toilets or using other water connected to appliances or
fixtures. The discharge from these items may back up into the
- Move any uncontaminated property away from the affected areas.
- Do not attempt to stop the flow of sewer backup through the
floor drain or any other sewer drain. Any added obstruction could
cause serious damage to your household drainage system and possibly
a catastrophic rupture of the household sewer drainage system.
Treatment of Rugs, Carpeting and Drapery For smaller, loose rugs,
and wall-to-wall carpet installed on racks, in-plant cleaning is the
best option. The germicidal and cleaning treatment has to be
thorough. Both the carpet and the floor surface have to be
completely cleaned and decontaminated. Germicides used for this have
to be effective even against the bacteria of the E-Coli family,
which is present in contaminated sewage. For wall-to-wall carpets
that are glued down, cleaning on-site may not be completely effect
and in-plant cleaning may not be viable economically or practically.
Contaminated padding is best discarded and should not be reused.
Steam clean or dispose of drapes.
Sewer BackUp Do’s and Dont's
- Do keep your sewer cleanout accessible and be knowledgeable of
where your sewer cleanout is located in case of a backup emergency.
The cleanout is a pipe located near the property line that rises
from your sewer line to about 4” above ground level and is capped.
It is often located in a basement, front yard, or back yard. If you
do not have a sewer cleanout or your sewer cleanout has become
buried, hire a licensed plumber to install a cleanout or raise your
- Do make sure you are covered for backups with your homeowner’s
insurance policy. Many homeowner’s insurance policies exclude damage
resulting from sewer backups. As such, homeowners often end up
looking to the municipality to pay their damages when their own
homeowner’s insurer denies their claim. It is possible for
homeowners to protect themselves against this risk. If you are not
covered, call your agent for information on costs and coverage
options. Most insurance companies offer a rider for water damage or
failure of a sump pump and this optional coverage is not usually
expensive. However, you must usually request that it be added to
The City of Northville is not automatically
liable for resulting damages whenever a sewer backs up. It cannot
assume financial responsibility for damages resulting from sewage
backups since most blockages are related to conditions that are
beyond the City’s control. That is why it is important that property
owners confirm that they are adequately insured, particularly if
areas of their home lie below ground level.
- Do save all receipts related to any repair, cleaning or damages
if a backup does occur. Also, take a lot of pictures with
descriptions of where the damage occurred. This information will be
useful when working with your insurance company.
- A sewer system is not a closed system and many things put into
the sewer can clog the system. Don’t dispose of grease down the
drain. Backups are often the result of a grease buildup in the
drain. Greasy or oily food waste should be put into a coffee can or
other container. Allow animal fats to solidify before scraping the
pan or throwing the grease container in the trash.
- Don’t flush diapers, sanitary napkins, tampons, paper towels,
tissues, or baby wipes down the toilet. Flushing such items can
easily cause a blockage in the drain.
- Do contact a plumber or plumbing supply dealer about preventive
measures, such as installing a “back-flow valve” on the lowest drain
in your home and periodic cleaning of the sewer lateral (private
line, which is the line that runs from the home to the street).
What a Home Owner Needs to Know
In 2001, the State of Michigan adopted Public Act 222 of 2001, known
as sewer backup legislation. The legislation clarifies when
municipalities are liable for sewer backups, sets standards to determine
the extent to which a municipality is liable for sewer backups, and
established a process to seek compensation when a backup occurs.
Persons making a claim for property damage or physical injury must
prove that the public sewer had a defect. In addition, it must be proven
that the governmental agency knew, or in the exercise of reasonable
diligence, should have known about the defect, and that the governmental
agency, having the legal authority to do so, failed to take reasonable
steps in a reasonable amount of time to repair, correct, or remedy the
If you experience an overflow or backup of a sewage disposal system
or storm water system, you must file a written claim with the City of
Northville within 45 days after the overflow or backup is discovered.
Notice should be mailed to the City of Northville, Attn: City Clerk, 215
W. Main Street, Northville, Michigan, 48167. Claim forms may be obtained
by calling the City of Northville Department of Public Works at
When presenting a written claim, you will be required to provide the
- Copies of receipts for cleaning costs, plumbing bills, or other
- List of the damaged items and receipts to prove the ages of your
items. Reimbursement for the Actual Cash Value of damaged items is
the maximum amount payable.
- Please make an attempt to provide pictures of anything you wish
to claim that was damaged due to the sewer backup.
The filing of a claim does not guarantee reimbursement.
