Along with our full range septic tanks and wastewater treatment plants.

We are the designers, manufactures and installers of our products, using our own technology, no other wastewater treatment company in New Zealand can say that. What that means is if you have a problem, we will sort it out. We don’t want our products installed with no backup and support. We don’t allow the installation of our products from unauthorized drain layers. This has eliminated problems and has given us a quality control of the entire process, from the design state, to the day of the install. No other manufacturer or installer of wastewater treatment plants will stand by you through the entire process. We know our product, we know how it works, we designed and built it. We do the whole job from start to finish.
