How to keep tree roots out of drain pipes.

There is always more than one way to skin a cat! Here are four commonly used methods to prevent tree roots from blocking your drain pipes, along with a general cost comparison:

1. Chemical Root Treatment: This method involves the use of chemical substances to inhibit root growth and entry into the pipes. The cost of chemical root treatments can vary depending on the size and length of the pipe being treated, the severity of the root intrusion, and the specific chemicals used. Typically, the cost ranges from $300 to $800 per treatment, and treatments may be required annually.
2. Physical Barriers: Installing physical barriers, such as root barriers or copper sulfate-impregnated strips, can prevent tree roots from reaching and damaging terracotta pipes. The cost of physical barriers will depend on factors like the length of the barrier required and the labor involved in installation. On average, the cost can range from $200 to $400 per linear metre, including materials and installation.
3. Pipe Renewal: Completely replacing the old terracotta pipes with more modern materials like PVC can effectively solve the problem of root intrusion. However, this method is typically more expensive and disruptive. The cost of pipe replacement can vary significantly depending on factors like the length of the pipe, depth of installation, and accessibility. As a rough estimate, the cost can range from $500 to $2500 per linear metre, including excavation, removal of old pipes, and installation of new ones.
4. Pipe Relining: Relining creates a new and seamless pipe within the old one, which is made of a durable and long-lasting epoxy resin material. This can extend the life of your pipes for several decades and prevent future root intrusion and blockages. Estimates range between $1,000- $1,500 per metre depending on the access to the pipes to be relined.

It’s important to note that these cost estimates are approximate and can vary depending on various factors like location, specific project requirements, labor costs, and contractor fees. It is recommended to consult with local professionals to obtain accurate cost estimates for your specific situation.

Tree roots chase liquid gold in drains

Did you know tree roots chase the liquid fertiliser in sewer drains?

That’s because the waste water running through your pipes is a constant source of moisture and nutrients.
In our dry continent a sewer pipe is an easy target for a tree root system that plays the long game.

Most of us use our plumbing every day. When we brush our teeth, wash the dishes and of course shower and flush our toilets, we send the waste water off to the sewerage treatment works.

We are also sending liquid fertiliser along the pipes for our trees to feast upon.

That waste water usually runs along the bottom 1/3 of the pipe.
More on that later….
