More Information

Do you have a septic system?

There are approximately one million septic systems in Ontario. They treat wastewater on properties are not serviced by a municipal sewer system.

If you live in a rural area or a small community, or if you have a cottage or other recreational property, chances are, you have a septic system.

Your Septic System - Friend or Foe

A septic system in an excellent means of treating household wastewater. On proper soils, and where dwellings are spaced well apart, septic systems can operate reliably for years. Treating sewage on-site, they eliminate the need for costly municipal sewers in rural areas.

Septic systems can also fail. Many malfunctions are investigated by Ontario’s Ministry of Municipal Affairs and Housing every year. They are often public health and environmental hazards and can also be very costly to repair. Many of these problems could easily have been prevented.

Problems with septic systems often stem from Improper use. A surprising percentage of householders don’t realize that they are using a septic system. Many people don’t realize that ongoing maintenance is required. Still others connect additional toilets, showers, hot tubs, and other water uses, without upgrading their septic system.

How Should A Septic System Work?

Buried in your yard and built to last, your home septic system may never have crossed your mind. But out of sight and out of mind, it still performs a vital task.

It’s simple: a tank, a network of pipes and billions of microscopic organisms. Yet it’s received every flush, every shower, and whatever else you and any else who’s lived in your house has ever poured down the drain.

Your septic system treats tonnes of organic waste each season. The tank treats sewage by letting the heavy solid material settle and allowing time for lighter “scum” to float to the top. This partly treated liquid then flows into perforated pipes called the leaning bed, where it filters into the ground and is further treated. Helpful bacteria and other soil organisms do the bulk of the work.

What Goes Wrong?

Over time, a septic tank accumulates solid material, which must be pumped out. Allowed to accumulate, this sludge may reach the outlet level and begin flowing into the leaching bed. There, it can plug the pipes or the bed.

Over the years, many septic systems are subject to increased usage. some were built for small homes or cottages, and were not enlarged as additions were made. The new volumes of water strain the septic systems, and it eventually gives up.

fortunately, regular septic maintenance and moderate water use can prevent these problems. And a bit of forward thinking when sizing and installing the system can allow some extra capacity to meet further needs. Bigger is better, and more capacity can mean a longer service life.

What happens when a septic system malfunctions?

Plenty. A clogged septic system can be hazardous to the environment and to your pocketbook. It can degrade water supplies and reduce your property value.

The required repairs can be messy, often involving excavation and replacement of the whole drainage field. Frequently, the local building Department will require replacement of the entire system and any damaged landscaping.

What are the symptoms of an ailing septic system?

Warning signs range from subtle to insufferable. The grass over the system may become unusually green and spongy to walk on. Toilets, showers and sinks might take longer to drain. Occasional sewage odors may become noticeable, often after a rainfall. Sometimes, homeowners discover grey or black liquids surfacing in their yards or backing up through fixtures into the house. Whatever the warning sign, it pays to fix it fast. A call to Dundas Septing and Excavation now can save big bucks later!

Operating Your Septic System

If in doubt – don’t pour it out!

Septic systems thrive on wastewater, but certain chemicals can cause major indigestion. Flushing even small amounts of paints, solvents, thinners, nail polish removers and other common household compounds (or pouring them down the drain) can poison the organisms that break down organic material.

Laundry bleaches, toilet bowl cleaners and caustic drain openers can also slow the treatment process, allowing sewage to pass through without proper treatment. And often, the chemicals themselves seep into the ground, sometimes contaminating wells or surface waters.

Septic systems cannot digest oils, grease and fat. Poured down the sink or toilet, they congeal in pipes sometimes plugging them. Grease can also combine in with detergents and flow into the drainage field where it may clog the soils. Fats can form a blop in the top of the tank, and interfere with the biological activities taking place. All oily waste should go out with the garbage.

Using your septic system to dispose or garbage is another no-no. In sink garbage disposals (“Garburators”) are unwelcome strains on the system. Disposable diapers, tampons and their holders, condoms, wrappers and many other kinds of refuse can plug and impair septic systems. If something doesn’t break down naturally, don’t flush it into your septic tank.

Preparations marketed as septic tank “cleaners”, “starters” or “enhancers” are of little value. Some have led to essential bacteria in the tank perishing and others may flush septic solids into the drainage fields. At best, these products are entirely unnecessary.

Your Drinking Water Depends On A Healthy Septic System

A septic system does some heavy-duty digestion. Viruses, bacteria and organic material are just some of the nasty things that it has to work on. And if not treated, they can travel a long way underground. If they flow into drinking water supplies, these organisms and compounds can cause diseases or other health or environmental problems.

Some components of sewage are very mobile once they enter the soil. And across the province, nitrate contamination of wells is already a concern for thousands of households.

To make matters worse, as a well draws groundwater toward itself, it also creates a funnel-shaped depression in the water table around it. This “cone of depression” may encourage septic effluent to follow a downward or lateral path toward the well. A household’s well water, even if it’s been good for years, can suddenly contain dangerous contaminants.

The less your well pumps, the less it tends to draw septic effluent and other contaminants toward it. And looking down the road, properly functioning septic systems help protect the quality of your community’s drinking water. Careful water use also extends the life of your septic system and helps it work better.

By conserving water, you lessen the odds of your water supply becoming contaminated. Maintaining your septic system helps protect your well and your neighbor’s.

How Much Goes Down The Drain?

Septic systems are by nature, slow-moving creatures. they work slowly, because the micro-organisms that treat wastewater can only digest so much at a time. Septic tanks also need some “retention time” for the solids to separate from the liquids.

This means that pouring less into your septic system allows it more time to work on each litre of waste, and each litre will be more completely treated. It also means that pushing too much, too quickly through your septic tank can cause untreated solid material to flow into the drainage fields, possibly clogging it.

Even if the pipes aren’t blocked, treatment won’t be adequate because solids have missed their chance to be broken down in the tank. Instead, they are discharged to the ground while still containing dangerous bacteria, viruses and pollutants in unacceptable concentrations.

Up to 200 litres of water are discharged to your system with each load of laundry and ordinary toilets use up to 20 litres per flush. So, too many loads of laundry in a day, or the extra toilets flushing from a party can load a septic tank with several times its usual daily flow. House guests, and the extra demands they place on your septic system are another concern. Older systems, often designated with smaller tanks and drainage fields, are especially vulnerable.

Fortunately, it’s easy to use water throughout the house. Whether washing vegetables, cleaning dishes, brushing your teeth or shaving, use the plug and water in the sink to avoid leaving the taps running.

Keep showers short and to the point. Run dishwashers and clothes-washers only when full, and use the cycles with the lowest number of rinses. Try to spread the clothes washing over several days. And when burying appliances, compare their water usage rates.

A tap leaking just one drop per second wastes about 10,000 litres of water per year. A silently leaking toilet can waste up to 20 times that amount. Day and night, water is pumped from you well, through your septic system – and all for naught. Since most leaks are easy to find and fix, water saving starts with stopping the drips.

Protecting Your Septic System

Driving cars or machinery over your septic system will crush it. The soil surrounding the pipes may also be compacted, making it less adept at absorbing sewage flows. Snowmobiles compress the snow cover over the field, reducing its natural insulating effect and increasing the risk of pipes freezing.

Septic tanks work better at warmer temperatures. Insulating the top of the tank (eg with polystyrene insulation) helps, and can avoid sewage freezing under extreme conditions.

Planting trees and shrubs (especially willows and poplars) near the field is risky, because their roots travel significant distances to seek water and can plug or damage the pipes. And watering of the grass over the field, whether by in ground systems or by hand, should be eliminated or minimized. Watering interfere with the soil’s ability to absorb liquids and break down wastes.

Discharged waste flows from home water treatment units, furnace condensate discharges and water softener backwash (which may contain salt concentrations) are strains that your septic system doesn’t need. These should go to leaching pits. Likewise, building sumps, as well as runoff from the roofs, patios and driveways, should be directed to splash pads away from the tank and leaching bed.

The drainage field is a specialized system, doing a vital job. Keep it dry, don’t plant near it and keep heavy things off the grass!

Maintaining Your Septic System 'Sludge Happens'

Even on a proper diet, a septic system still needs regular check-ups. Though a septic tank is designed to store solid materials, these solids build up and limit the settling of particles entering it. And if septic solids are allowed to flow into the drainage field, the field may become clogged.

Sludge decreases the retention time in your tank – though it appears to be working normally. It might take a year, or it may take five or more but “sludge happens”.

The smaller the tank, and the more people using it, the faster the sludge accumulates – and though larger tanks have more capacity, these too will eventually fill. Once it’s too late, you’ll know your drainage field is too congested to do the job. Your drains and toilets slow down, stop, or may even start to run backwards.

Having your septic tank inspected every two years is cheap insurance!

It costs less, per year, than the sewer changes levied in many urban areas. And gives you the confidence that your tank has its whole design capacity ready to treat your household’s wastewater.

Summer, and early fall are the best times to pump out your septic system. This leaves time before winter, for the tank to refill and for bacterial action to become re-established. Also the ground won’t be frozen, and the spring water table, which can create buoyancy problems for septic tanks, has receded. Particular care should be taken when pumping tanks made of lightweight materials such as polyethylene, fibreglass and steel.

A septic system pump-out is less than a hundredth the price of an overhaul.

So the choice is yours. Pay a little now… or a lot later!

What To Do When There's A Problem

When your drains slow down, or toilets back up, its time for immediate action.

You are required by law to report any problems to your local Building Department, before proceeding with repairs. Once a permit has been issued by the Building Department, call a licensed contractor. Detail the full extent of the problem, giving specific details as to when your first noticed any symptoms.

Repairs can range from clearing a few lines, to replacing entire drain fields and land filling contaminated soil. Costs vary from a few hundred dollars, to thousands.

The extent and cost of required repairs depends on how far you let the problem go.

Your Septic System And The Law

A privately serviced home means independence. More than just no sewer bills, it’s an opportunity to really “live off the land” – off your land – without relying on someone else to take care for your waste.

A septic system is also a responsibility. Neglected or over-used, your septic system may affect your water supply and the wells in your community.

Where a failing septic system becomes a matter of public health, remediation is required by law.

All residential septic systems in Ontario are regulated by The Ministry of Municipal Affairs and Housing, under Ontario Building Code Act. the Building Code requires that a permit be obtained, prior to the construction, installation, extension, enlargement or alteration of any sewer system, or any building connected to a sewer system. A Building Permit is obtained from your local Building Department.

Alternate Sewage Systems

Holding Tanks:

Some on-site systems are designed only to store wastewater, which is then pumped form the tank and trucked off-site for treatment. Often used where septic systems cannot be accommodated, these holding tank systems require an alarm to warn when nearly full, and an on-going contract with a pumping service.

Aerobic Systems

Several mechanical alternatives to septic systems are available on the market. These are active systems, using compressors or motors to introduce air into the treatment of wastewater. Most of these systems bubble air through wastewater, or use rotating discs to expose the sewage to air. These systems are required to have an on-going maintenance contract with the manufacture or their agent.

While aerobic systems can provide a higher level of treatment than standard septic tanks, they also have many moving parts and electrical connections, and require far more frequent servicing than a conventional system.

New Technology:

New designs in wastewater treatment are reaching the marketplace every year, as new technologies are further developed and demonstrated. Systems employing some very high tech, and some very “old tech” are providing promising results.

The Ontario Rural Wastewater Centre is a non-profit organization tat monitors and tests many of these new products, and conducts independent research in this area.

Call your local Building Department if you are considering one of these systems, to ensure that they are approved for use in your area.

The Bottom Line....

Proper care and feeding of your septic system couldn’t be easier. Fix all the leaks, be frugal with your water and do not flush chemicals, garbage and grease.

Have your septic system checked at least every five years and pumped when required.

Lastly, keep a maintenance schedule on your septic system. Record the physical layout of the system, the dates it was inspected, the kind of work done, and the name of the licensed contractor who performed the work.

Remember…. A well maintained septic system can run for decades. An abuse or neglected one can fail tomorrow.
