What we pump

The work, in the order people ring about it.

Everything McMinns Pumping Systems handles, in the order people ring about it.

01

Septic

Septic tank cleaning

The standard household pump-out. We lift the lid, vacuum the tank down, check the outlet and leave the lid seated properly.

02

Grease

Grease trap cleaning

Kitchen grease traps emptied and washed out on a schedule that keeps the council and your kitchen happy.

03

Liquid

Liquid waste removal

Bulk liquid waste taken away under licence and tipped at a licensed facility, with the paperwork to prove where it went.

04

Wastewater

Wastewater treatment

Onsite wastewater systems pumped, serviced and checked over, whatever brand is in the ground.

05

Waste

Waste oil collection

Waste oil collected and sent for recycling rather than tipped, with the record to show it.

06

Portable

Portable toilet hire and service

Portable toilets delivered, serviced and collected. Site sheds, events, and jobs that run long.

07

Vacuum

Vacuum tanker hire

Vacuum tanker hire handled on the same visit, so it is not another trip and another bill.

What happens on the day

Straightforward, start to finish.

A phone call, and it is booked

One conversation. You hear what it costs, you hear when we can be there, and that is the booking done.

Finding it is part of the job

Under the lawn, under a garden bed, under a slab someone poured over it. We locate the lid and uncover it before anything else.

Emptied properly, not skimmed

A tank is not done when the liquid is gone. The crust and the settled sludge come out too, which is the part that decides how long before you need us again.

The paperwork follows the load

Tipped at a licensed facility, recorded, and available to you if a council or a buyer ever asks where it went.

Your service report, done at the tank

Aerated systems need a service record for the council. It gets filled in while we are there, not from memory afterwards.

We leave it safe

An unseated septic lid is the most dangerous thing on a rural block. Ours go back properly, every time.

Not the same as the next truck

Straight answers

The questions we get asked most.

How often should a septic tank be pumped?
For most households it is every three to five years, and it depends on tank size and how many people live there. If it has been longer than five years, or you have just moved in and nobody can tell you when it was last done, book it.
How do I know if mine needs doing?
Slow drains through the whole house, gurgling, a smell near the tank, or wet ground and greener grass over the trench. Any of those means ring, do not wait.
Do you need to find the lid, or do I?
We can find it. If you know where it is, tell us and we are faster. If nobody has looked in twenty years, that is a normal job for us.
Can the truck get to my tank?
Usually. Tell us if the tank is behind a locked gate, down a steep drive, or more than about thirty metres from where a truck can park, and we will bring the right hose.
What happens to the waste?
It goes to a licensed facility and it is documented. Ask for the docket any time you want it.
Do you do the council service report as well?
Yes. Aerated systems have to be serviced on a set interval and reported. We do the service and fill in the report at the tank, so you are not chasing paperwork later.
How often does a grease trap need doing?
Most kitchens run somewhere between monthly and quarterly, and your council sets the minimum. We will tell you honestly if you are paying for visits you do not need.
How much does it cost?
It depends on tank size, access and how long it has been. Ring (08) 8988 1885 with your address and you get a real number, not a range.
