Septic Systems Vs. Holding Tanks

If you live in Muskoka, you most likely have a septic system or a holding tank. Both are effective methods of waste management; however, each has its own set of drawbacks and advantages. Things such as cost, installation, capacity, maintenance and bylaws all play a part in what type of system is preferred for your property.

Continue reading for a summary of how septic systems and holding tanks work, as well as their advantages and disadvantages.

What is a Septic System?

A septic system is essentially a home’s individual waste management plant. They are classically set up with the waste entering the tank, undergoing decomposition and exiting the tank through the leaching bed. The tank will have 2 to 3 chambers with an equal number of access points. As the waste enters the tank, it begins to settle and naturally separates into three sections. The sludge (aka the solids) settles to the bottom, the wastewater rests in the middle and the scum (aka things that don’t belong, such as wipes) rises to the top.

As the first chamber fills it overflows into the second chamber. From here the waste begins to decompose and the natural bacteria, that is already present, breaks it down into harmless biproducts. The treated waste then exits through a series of piping called the leaching bed and is released back into nature.

What is a Holding Tank?

A holding tank is exactly what it sounds like. It is a large tank, with one chamber, that will store your household waste until it can be removed. It typically only has one access point and has a larger holding capacity than a septic tank. Their holding capacity can vary from 800gl to 2000gl. The treatment and release of waste is not a part of this system.

Septic Systems

Advantages

Septic systems are constantly moving waste; therefore, they only need to be pumped out every 3-5 years. This pump out frequency depends on the usage and the size of the tank. If the septic is treated properly and has regular maintenance, it can last for many decades.

Disadvantages

The main downside to this waste disposal method is the installation and repair costs. Depending on the type of septic and the location, the costs can range from $20,000 to $30,000. They also require at least 450 square feet of space and proper filtration sand for the leaching bed.

Holding Tanks

Advantages

Holding tanks, on the other hand, are more versatile since they come in a variety of sizes and do not have a tile bed. This allows them to be placed in locations where septic systems would not fit or where treated waste cannot be discharged, such as on islands. Because they are simply a large tank, they are also much more cost effective to install. The cost of installation typically ranges from $7,500 to $10,000.

Disadvantages

Although the installation costs are much cheaper, the maintenance costs will most likely be higher than septic systems. This is because holding tanks need to be pumped out on a more regular basis. Depending on usage and size, pump outs can be required as regularly as 2 or 3 times a year.

Bylaws

The bylaws regarding waste management may vary depending on your municipality, however, there are some standards that remain the same across the province of Ontario. Generally, septic systems are the waste management system of choice. Exceptions to this include instances where there is not enough space for a leaching bed or if pollution in nearby waterways is an issue. Holding tanks are also permitted as a way of expanding an existing system or as a temporary waste management situation.

Conclusion

In the end, the best system for your property is a matter of location, installation, maintenance and community by-laws. Taking all these factors into consideration will give you a better idea of why your property has the waste management system that it does. They should also give you an idea of the system’s advantages and disadvantages as well as the type of system you would prefer to have for any future property purchases.
