Treatment system due? We service it properly.

Everything the tank might need.
Everything Bennett's Environmental handles, in the order people ring about it.
01
Septic
Septic system supply and installation
New systems supplied and installed, sized to the block and the number of people actually living on it.
02
SuperTreat
SuperTreat AWTS
SuperTreat AWTS, on a day that suits you and with the site left as we found it.
03
Council
Council approval services
Council approval services handled on the same visit, so it is not another trip and another bill.
04
Concrete
Concrete tanks and products
Concrete tanks and products — quoted before we start, and finished the same day where we can.
05
Water
Water tanks
Rainwater tanks drained, cleaned out and refilled, so what comes out of the tap is what you thought was in there.
06
Retaining
Retaining walls
Retaining walls, on a day that suits you and with the site left as we found it.
How the day goes.
You ring, we give you a day
No answering service, no ticket. You get a person, a price and a day that suits the truck and suits you.
We find the lid before we start
If you have never had it pumped, we locate and uncover the tank. Old lids under a garden bed are our normal Tuesday.
Hose to the tank, truck stays put
The hose does the walking so the truck does not have to. Sludge, crust and liquid all go, not just the easy layer off the top.
It is tipped where it should be
Waste goes to a licensed facility. If you ever need the docket, we have it.
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.
The lid goes back properly
Seated, weighted, and safe to walk over. That last part matters more than anything else on this list.
