Need a septic system designed in Northland? Gumboots Consulting Engineers designs onsite wastewater systems — commonly called septic systems — for new builds, replacements, and upgrades throughout Kerikeri, Whangarei, Paihia, and the Far North. Our designs meet Northland Regional Council's TP58 requirements and are accepted for building and resource consent.
In Northland, "septic system design" and "TP58" are the same thing. TP58 is the Northland Regional Council's technical publication that governs how onsite wastewater systems (septic tanks, effluent disposal fields, aerobic treatment units, etc.) must be designed and installed. If you need a septic system, you need a TP58 report.
The majority of rural and lifestyle block properties in Northland are not connected to reticulated sewer and require an onsite wastewater system. This includes most of:
Full TP58 septic system design for new homes in Northland — soil testing, system selection, sizing, and layout to meet NRC requirements and secure your building consent.
Failing or non-compliant septic system? We assess the existing system, identify the cause of failure, and design a replacement that meets current NRC standards and council requirements.
Lot-by-lot TP58 assessment for subdivision resource consent — confirming each proposed lot can accommodate an onsite wastewater system before the land is sold. Part of our subdivision engineering package.
Permeability testing and soil analysis determines whether standard trench disposal, mound systems, or advanced treatment units are required. We conduct all soil testing in-house as part of the design process.
Based in Kerikeri, we design septic systems throughout Northland. Fast turnaround, TP58 compliant, accepted by all Northland councils. Call for a quote.
