Frequently Asked Questions
What are the signs that my septic tanks needs emptying?
Smelling or wet areas around the tank and drainage field, overflowing drains, or toilets and sinks that are slow to drain.
How often should my septic tank be emptied?
For an average family of four we recommend your septic tank be serviced every 3 - 4 years, and at least every three years for a larger family.
The frequency is also dependant on what goes into the system, how many people use it, the capacity of the tanks, and whether or not you recycle greywater.
How long does it take to empty the septic tank?
Providing everything is straightforward, about 45 mins.
How close do you need to get to the septic tank?
The closer the better. Our trucks routinely carry about 50m of hose, if the distance is greater than this then we will need to know so we can bring extra hose.
My property is well landscaped. Do your trucks leave a mess behind?
Our fleet of trucks are modern and well maintained. They do not drip oil on driveways and our team makes every effort possible to protect your property while undertaking any work.
The last company to cleaned my septic tank only half emptied it as thier truck was too small. Will you fully empty my tank?
