The Purpose of a Septic Tank

One of the most efficient ways of eliminating waste through the natural filtering process of the soil is through septic tanks. These systems help in filtering wastewater and dispensing water for recycling. They are a simple and affordable solution to manage waste within a property. Depending on the number of people living in your house, you can decide on the septic tank size. Moose Creek Precast Inc. provides quality and durable septic tanks in different sizes in and around Ottawa.

How Do Septic Tanks Work?

A septic tank is the central part of your septic system, responsible for storage and filtration. It has two sections, one section being 2/3rd of the tank and the other being 1/3rd of the tank. The first section has a top layer, a liquid layer, and a sediment layer. Both units have billions of natural bacteria for the treatment of household waste. They help in breaking down solids and sludge. When the wastewater leaves the septic tank and enters the leaching field, a different type of bacteria that requires oxygen filtrates and decomposes the waste particles.

The Advantages of Concrete Septic Tanks

Here are the reasons why our concrete septic tanks in Ottawa are the right choice:

  • Water-tightness: Concrete is naturally watertight, while other materials, such as plastic, are subjected to treatments before holding water. This natural water-tightness will minimize the risks of leakages.

  • High effluent capacity: The effluent and wastewater in your tank, known as sludge, will decompose with time and settle to the bottom. You will have to pump your tank once it reaches its 2/3 capacity of solids or every 3-5 years.

  • Low-risk installation: Concrete septic tanks are sturdier than plastic, so there is a greater chance of damage or deformation in transportation and installation.

  • Durability: Concrete septic tanks are known to last years and are strong, durable and sustainable.

Tips for Effective Septic Tank Maintenance

Regular pumping and maintenance are necessary to remove accumulated solids and sludge from your septic tank, preventing backups and other issues. At Moose Creek Precast Inc., we offer septic tank maintenance services to keep your system running smoothly for years. Here are some maintenance tips for septic tanks:


  • Inspect and pump your septic tank frequently: Get your septic system inspected and pumped every three to five years by a professional.

  • Use water efficiently: Too much water can overload your septic system and cause failure. Fix leaks, install low-flow fixtures, and spread-out water usage to avoid overwhelming the system.

  • Don't flush or pour harmful materials down the drain: Products such as chemicals, non-biodegradable products, grease, and oils can clog or damage the septic system, leading to costly repairs.

  • Protect the area around the septic system: Do not drive over the septic system or compact the soil. Plant grass over the system to prevent soil erosion and provide natural filtration.

  • Maintain your drain field: Do not plant trees or shrubs over your drain field and do not cover the area with hard surfaces like concrete or asphalt. These actions will interfere with the system's ability to properly treat and dispose of wastewater.


Whether you need a one-time inspection or ongoing maintenance services, we can help. We'll work with you to create a custom maintenance plan that meets your specific needs and budget, ensuring your septic system stays healthy and reliable.

Holding Tank

Holding tanks are generally used in very small lots, environmentally sensitive locations, and places with high water tables where a septic system cannot be used. It is the only storage for household waste until it is pumped out. An audible and visual alarm must be installed to indicate the amount of waste in the tank.
