Sanitary Sewer
The sanitary sewer consists of around 680 kilometres of pipe that connects residential and commercial properties to the wastewater treatment plant and lagoons. Treated wastewater is then discharged into the Fraser River and other creeks and streams.
Nearly $2 million every year goes towards operating the wastewater treatment plant, which accounts for nearly half of the $4.5 million annual cost to maintain the sanitary sewer. Another significant expenditure is associated with responding to around 500 calls the City Utilities Division receives annually about blocked sanitary sewers.
As such, it is crucial that substances and waste materials entering the sanitary sewer system do not:
- Harm the environment.
- Damage the water treatment plant.
- Complicate the treatment process.
- Pose a health threat to maintenance and repair crews.
If a matter or liquid can reasonably be thrown into the garbage, do not flush it down the toilet or wash it down the drain.
SANITARY SEWER SYSTEM BY THE NUMBERS
-
$4.5 million - Annual sanitary sewer operations and maintenance.
-
$1.9 million - Annual wastewater treatment operations.
-
500 - Annual number of blocked sanitary sewer service requests.
-
$420,000 - Annual cost of responding to blocked sanitary sewers and grease removal.
-
$1.7 million - Capital cost of vacuuming and flushing trucks to help remove blockages.
Sanitary Sewer Blockages
Blockages in sanitary sewer mains can cause sewage to backup into a residence. Blockages may result from:
- Vegetation roots growing into the line.
- The improper disposal of items such as grease, wipes, diapers, washing machine lint, and other items flushed down the toilet.
Failing to act in a timely manner may increase damage to property and to neighbouring properties.
What to do if a Blockage Happens
In the event of a blockage, the first step is to contact the City Service Centre at:
Phone: 311
Email: 311@princegeorge.ca
The City will help identify the blockage's source.
- If the blockage is in the City's sanitary sewer main, the City will clear it.
- If the blockage is not in the sanitary sewer main, the property owner is responsible for clearing it.
Non-Sanitary Sewer Main Blockages
Property owners are responsible for removing any blockages within the sanitary service connection or building sanitary sewer. The following steps should be taken:
- Contact a plumber or licensed technical for assistance.
- Residents with homeowner's or other property insurance should also notify the insurance agent to see if the claim is covered.
- Document all actions taken (calls, contacts, costs) and take photographs of any damage caused.
For more information:
Property owners must keep the sanitary cleanout (the sanitary sewer connection's access point to a building) clear.
- Do not bury or pave over the cleanout. Any damage caused in locating the cleanout is the property owner's responsibility.
- If a cleanout needs to be raised or lowered or if the cap is missing or damaged, contact the City immediately.
- Any damaged caused to the cleanout due to the property owner's negligence will be repaired by City staff at the owner's expense.
- Cleanouts located in driveways are required to be in a valve box supplied by the City and are installed by the property owner or contractor.
sanitary Sewer dos and don'ts
DO:
- Use a strainer over the drain in sinks, tubs, and showers, and empty it into the garbage, not the toilet.
- Place food scraps in the compost or garbage, scrape dishes into the garbage, not the sink.
- Use biodegradable products for cleaning and doing laundry.
- Use the manufacturer's recommended amount of detergent for cleaning (the average household uses three times more than recommended). Cutting back also saves money.
- Place a garbage can in the bathroom to dispose of solid wastes such as disposable diapers, condoms, paper towel, and personal hygiene products.
- Take pharmaceutical products to a pharmacy to be properly disposed of.
- Pour liquid fats, oils, and grease into a jar or container with a lid to cool, and then throw it in the garbage. Wipe down greasy pots and pans with a paper towel, prior to washing them, in the sink or dishwasher.
- Use the "3 Rs": Reduce, Re-use, and Recycle.
DON'T:
- Use the toilet as a garbage can.
- Pour fats, oil, or grease down the drain as they will solidify in the cold pipe.
- Pour sour milk down the drain (One litre of three per cent milk has enough fat in it to cover the surface of an Olympic-sized swimming pool). Dispose of it in the garbage.
- Wash food scraps, tea leaves, coffee grounds, or eggshells down the sink.
- Flush razor blades, condoms, pharmaceutical products, cigarette butts, nail polish remover, toilet rolls, or other non-biodegradable products down the toilet.
- Pour chemicals, paint, motor oil, pesticides, or any other harmful products down the drain. Check recycling depots for disposal information. Note: Improper disposal may result in fines.
- Flush out a commercial grease interceptor with hot water to clean it or wash it in the dishwasher. Remove all grease and dispose of it appropriately.
- Use excessive detergent, as it contains large amounts of oil, grease, and fat. It makes cleaning and treating waste water difficult and costly. This will result in less phosphate entering the water table, and will prevent excess algae growth in the water.
repair and reimbursements
The City will be responsible for any defects identified in the service connection. Any repairs required on the building's sanitary sewer side are the property owner's responsibility.
Reimbursement
Reimbursement will be provided if the defect is within the service connection up to a maximum of:
- $185.00 for CCTV work
- $30.00 for a service locate
- $20.00 dollars for a DVD (plus tax),
If there are issues or problems on both sides, a partial reimbursement may be possible. This refund will only be approved once in a three-year period.
A DVD of the CCTV inspection must be dropped off at:
Public Works
3990 - 18th Avenue
Prince George, BC V2N 4R8
Canada
If the CCTV inspection video does not meet City standards it will be returned without reimbursement.
Claims Against the City
The City is not presumed to be responsible for the consequences of a blocked sanitary sewer line simply because the blockage is on the City side. The City is governed by the British Columbia Local Government Act and is considered immune against certain nuisance actions caused by a breakdown or malfunction in the sewer system.
For more information:
The City will also not provide reimbursement if the City has not been notified of a blocked sanitary sewer at the time of an incident.

Phone: 311
Email: 311@princegeorge.ca
required documentation
Ask a plumber or licensed technician these questions and document the answers:
- Was a snake, root cutter, or another method used to clear the blockage?
- If a root cutter was used, what size was it? Note: This is only a temporary solution
- How many times did the plumber work the line with the snake or root cutter? (It usually takes several passes to ensure complete removal a blockage)
- What was the total distance of root cut or snaked? (This will identify if the entire line was cleared)
- Where was the blockage located?
- Did the plumber suggest a CCTV inspection? (This is a costly expense but is recommended for recurring sanitary sewer backups or problems)

Source Control Program
Prince George's source control program identifies harmful substances before they can enter the city's wastewater, storm water, and groundwater. Many products routinely used at home and at the workplace may cause a number of problems including:
- Posing a risk to public health and safety.
- Damaging the City's waste water treatment plant and affect treatment processes.
- Affecting surface and groundwater quality.
For more information on preventing wastewater, storm water, and groundwater contamination:
| | The City started the Source Control Program in 2015 to safeguard public and worker health, property, City infrastructure, and the environment. City staff work with residents and commercial, industrial, and institutional operations to ensure they follow Prince George's sewer bylaws. Education and outreach are key to the program's success. Other source control program activities include: - Building plan and development review.
- Industrial monitoring.
- Compliance sampling.
- Issuing waste discharge permits.
- Site inspections.
- Investigations.
- Spill prevention and response.

Information from the Public Open House held January 30, 2019:
| 3 | Storm Water and Sanitary Systems | Storm Water and Sanitary Systems | 317 | 1 | | | Commercial premises sometimes produce wastewater that requires controls to ensure compliance with local regulations. Operations that could potentially discharge oils, sand, and grit are required under the BC Plumbing Code to install an interceptor device to protect the sanitary sewer system. Controlling harmful substances at the source prevents dangerous wastewater discharges and brings other benefits like: - Improving workplace safety.
- Avoiding costly clean-ups.
To track oil-water separator calculations for clean out requirements:
| 3 | Storm Water and Sanitary Systems | Storm Water and Sanitary Systems | 317 | 1 | | | Wastewater discharges that do not meet the requirements outlined in the City of Prince George Sanitary Sewer Bylaw can have serious consequences on public health and safety, municipal infrastructure, the wastewater treatment processes and the environment.
Waste Discharge Permits are issued to industries, businesses, and institutions that discharge significant, non-domestic wastewater containing specified chemical contaminants into the sanitary sewer system.
Waste Discharge Permits issued by the City:
- Are site-specific regulatory authorisations granting permission to discharge waste to the sanitary sewer.
- Contain discharge requirements and best management practices designed to limit the impact of the discharge and the potential for illegal discharges.
- Specify requirements for wastewater treatment, effluent quality, monitoring and reporting.
- Are of specified duration.
- Are authorisations that may be amended, suspended or cancelled.

Storm Water System
The City's storm water drainage system collects runoff water from rainstorms, snow melt, and residential and commercial water usage. The water travels through a network of pipes, culverts, and ditches, eventually making its way to a natural water course or retention pond.
Storm water management is essential to prevent:
- Flooding
- Erosion
- Sedimentation/degradation of water quality
- Negative impact on aquatic life
Urban development impacts peak flows by increasing impermeable surface areas; storm water from building roof drains and asphalt parking lots flow into catch basins. It then enters the storm sewer system or a recharge chamber.
Be mindful about water consumption. Washing vehicles and over-watering lawns, can strain the system.
| | Storm Water System
STORM WATER SYSTEM
Sediment and debris in the system are removed, with regular maintenance, to prevent blockages and flooding.
SYSTEM BY THE NUMBERS - 901 culverts
- 5,716 catch basins
- 4,063 manholes
- 332 discharge points (outfalls, recharge tanks, discharge structures, etc.).
- 423 kilometres of below ground piping.
- 1,100 kilometres of open ditch or drainage channels.
- 28 storage basins (detention and retention ponds).
- 211 inlet structures.
- 6 storm lift stations.
| 1 | Storm Water and Sanitary Systems | Storm Water and Sanitary Systems | 317 | 2 | | | Preparing for the Spring Melt
Spring not only brings warmer temperatures, but also increases the threat of flooding. City utility crews travel throughout the city to monitor and report on problem drainage areas to catch issues before they get worse. Crews also track major ponding as they occur to prevent traffic problems and local flooding. These "ponding patrols" are on duty during peak melt season.
The City of Prince George encourages residents to bring to the City's attention large puddles or flooding concerns. To report a problem:
Service Centre
Email: 311@princegeorge.ca
Phone: 3-1-1
SPRING MELT TIPS - Make sure no debris (like leaves), plastic, or paper covers catch basin grates.
- Clean gutters and downspouts.
- Ensure proper drainage and grading away from properties.
-
DO NOT use lawn sprinklers to melt snow. Offenders will be subject to a City fine.
- If possible, work with neighbours to divert water to the closest storm drains.
- Shovel or blow snow away from property foundations, but not onto the street. Snow and ice can block storm drains.
- Residents in low-lying areas should be aware of flooding risks to their properties and plan accordingly.
FLOOD MITIGATION Flooding can happen for many reasons like surface water having no place to go due to frozen ground or storm system overloads due to large snow melts and rain.
Some ways to mitigate and prevent flooding include:
- Using sandbags, plastic sheeting, ditching, and clearing clogged drains and culverts.
- Purchasing sump pumps for homes that are at risk from basement flooding.
