Septic Tank Installation

Traditional septic tanks are the most common choice and work by separating solids and scum from wastewater. They are generally affordable, easier to install, and require less maintenance, making them ideal for most homeowners.

Septic Tank Cleaning

Regular cleaning extends the lifespan of your septic system. By sticking to a routine cleaning schedule, you reduce the need for costly repairs and replacements. The accumulation of sludge and scum is kept in check, which means fewer mechanical failures and a longer-lasting system.

Septic Tank Emptying vs. Deep Cleaning

What is the difference?

Standard septic tank emptying (or pumping) removes the liquid effluent and floating scum to prevent overflows. However, over time, heavy sludge hardens at the bottom and sides of the chamber.

Our septic tank cleaning service utilises our in-house high-pressure water jetting equipment to break down this stubborn sludge, thoroughly washing the interior walls and ensuring your system operates at maximum capacity.

We highly recommend a full clean if your tank hasn’t been serviced in several years.

Signs Your Septic Tank is Full

Don’t wait for raw sewage to flood your property. You should contact us immediately for a pump-out if you notice toilets draining slowly, gurgling sounds coming from your plumbing, pooling water around your drainage field, or persistent foul odours outside your home.

Ignoring these warning signs can lead to severe soakaway damage and costly repairs.

How Often Should You Empty Your Tank?

To prevent sludge from entering and destroying your soakaway network, most domestic septic tanks should be emptied every 12 months.

However, this varies based on tank size and household usage.

We can assess your system and set you up on a hassle-free, automated maintenance schedule so you never have to worry about remembering to book a pump-out again.
