Maintaining Your Cistern or Septic Tank

A septic tank is an underground container purposed for the basic on-site treatment of domestic wastewater. With proper maintenance and periodic repair, septic systems can last up to 40 years. However, several factors can reduce that lifespan, and potentially leave your home or property in an enormous mess.

Cisterns are waterproof containers specially purposed to hold liquids such as potable water. While it may be tempting to leave your cistern tank and containers as they are for long periods of time, we generally recommend that you perform basic level maintenance at least once a year.

If you find that your water looks, smells, or tastes different, then we typically recommend getting your cistern tank inspected before performing more frequent maintenance.

Plastic or Concrete, Which is Better?

There are a number of factors that you should consider when deciding between a plastic or concrete septic tank. To help you determine which product will best meet your needs, we’ve provided a list of important information to consider below.

Concrete Tanks

  • Very durable with a long life expectancy. Concrete septic tanks are much more durable compared to plastic alternatives, and can last as long as 40 years with proper maintenance.
  • Less maintenance required. Due to the fact that concrete septic systems are so durable, they tend to require less maintenance than plastic tanks.
  • Environment-resistant. Again, thanks to the durable nature of concrete tanks, they are much less likely to become compromised by environmental factors. Driving over a buried concrete septic tank will not cause it to be crushed or damaged. Similarly, changes in soil conditions or spreading tree roots will not affect the structure or functionality of the tank.

Plastic Septic Tanks

  • Crushing, breaking, and rupturing. Plastic septic tanks are more susceptible to damage than their concrete counterparts. If someone drives over a buried plastic tank, it could potentially be crushed. They can also break and warp over time, and do not have as long of a lifespan.
  • Maintenance requirements. Plastic septic tanks tend to require more frequent maintenance.
  • Environmental damage. In contrast to concrete systems, plastic tanks can be compromised by changing soil conditions, tree roots, or vibrations.


Signs you should watch out for include:

  • Water pooling near the septic system
  • Backups or slow drainage of sinks, tubs, showers and toilets
  • Bad smells around your home or property
