What we get called out for most.
Everything 100% Liquid Waste Solutions handles, in the order people ring about it.
01
Septic
Septic tank pump out service
The standard household pump-out. We lift the lid, vacuum the tank down, check the outlet and leave the lid seated properly.
02
Septic
Septic tank cleaning
Septic tank cleaning handled on the same visit, so it is not another trip and another bill.
03
Treatment
Treatment systems
Aerated treatment systems serviced, pumped and left running the way the manufacturer intended.
04
Liquid
Liquid waste collection
Bulk liquid waste taken away under licence and tipped at a licensed facility, with the paperwork to prove where it went.
05
Household
Household grease traps
Kitchen grease traps emptied and washed out on a schedule that keeps the council and your kitchen happy.
06
Commercial
Commercial grease trap cleaning and maintenance
Commercial grease trap cleaning and maintenance handled on the same visit, so it is not another trip and another bill.
What actually happens on the day.
You get a person, not a queue
Ring and someone who drives the truck answers. You get a price and a day on that call, not a callback.
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.
The council report is handled
Treatment systems come with paperwork obligations. We do the service and the report together, so nothing is chased later.
The lid goes back properly
Seated, weighted, and safe to walk over. That last part matters more than anything else on this list.
