Hydrovac is the largest privately owned wastewater treatment system service provider in New Zealand. We can service most wastewater systems (see the list below) and if it isn’t a fault we are unfamiliar with, we maintain very strong links to major manufacturers to ensure that we have access to the knowledge required to resolve the issue.
Our team of trained technicians operate over an area stretching from Warkworth down through greater Auckland, Coromandel, Waikato and into Taranaki. We also service Waiheke, Rakino and Kawau Islands. We also have a full wastewater team in Canterbury.
Our fleet of vans are fully equipped with stock and tools to allow our techs to tackle virtually any task on site and, if not, we can usually source the required parts within 24-48 hours.
We can help with servicing, cleaning and maintaining:
- Commercial wastewater plants and pump stations for schools, businesses, council toilet blocks, prisons and more
- Residential wastewater treatment systems
- Commercial sewer systems and chambers
- Septic tanks. Most tank manufacturers recommend six-monthly services to validate the warranty requirements. Find out more HERE.
- Irrigation field remediation and replacement
- Macerator pumps
Did you know we service places off the beaten track? Like council toilets at beaches, rivers, mountain areas & tramping tracks!



If your system is flooded or the build-up of sludge and crust is too high, our Hydrovac trucks can come and vacuum your system to get it back to almost new.
Our customer service desk is answered by real people in real time with real knowledge and we can usually have your issue resolved at the time, on the same day or within 24 hours.
We operate a 24/7 phone service and an on-call tech is available at all times for the most urgent need.
