Three Waters Operations and Maintenance

Maintaining water networks with proven precision and operational excellence

InterGroup provides specialist three waters maintenance services across New Zealand, supporting councils, utilities, and infrastructure owners with the inspection, cleaning, and rehabilitation of critical water networks.

Our services cover everything from routine pipe cleaning and condition assessment through to emergency response and network restoration. We help ensure stormwater and wastewater systems remain compliant, reliable, and operating efficiently.

With one of the country’s most extensive fleets of vacuum loading, hydro-jetting, and CCTV inspection equipment, combined with highly trained operational crews, we deliver accurate diagnosis and effective field solutions at scale.

With decades of experience supporting local authorities and major infrastructure programmes, InterGroup’s three waters services are designed to reduce network failures, improve asset visibility, and support long-term infrastructure planning in line with New Zealand environmental and compliance standards.
