Septic System Installation in Auckland
Blake Civil Construction provides septic system installation in Auckland for rural properties, lifestyle blocks, and semi-rural developments that sit outside the reticulated sewer network. We install traditional septic tanks, aerated treatment systems, and disposal fields — all designed and consented to meet Auckland Council on-site wastewater rules.
What is Septic System Installation in Auckland?
Properties in rural Auckland — from Coatesville and Dairy Flat through to Kumeu, Helensville, and Warkworth — rely on on-site wastewater treatment because there is no council sewer to connect to. A septic system collects, treats, and disperses household wastewater on your own land. The system needs to be sized correctly for your household, matched to your soil type, and consented through Auckland Council before installation begins. We handle the full process — site assessment, soil percolation testing, system design, council consent, excavation, tank installation, disposal field construction, and final sign-off.
- Traditional septic tank installation with gravity-fed disposal fields
- Aerated treatment system (ATS) installation for sites with challenging soil conditions
- Disposal field and land application area design and construction
- Soil percolation testing to determine ground absorption rates
- Auckland Council on-site wastewater consent applications and inspections
- Septic system replacement and upgrades on existing rural properties
Based in Coatesville — right in the heart of rural North Auckland — Blake Civil Construction installs septic systems across the region every month. Our licensed drainlayers know the local soil conditions, council requirements, and system types that work on Auckland's rural properties.
When You Need Us
When You Need Septic System Installation in Auckland in Auckland
New Build on a Rural Lifestyle Block
Your new home is on a rural section with no sewer connection. You need a fully consented on-site wastewater system designed and installed before you can occupy.
Failing Septic System Needs Replacement
Your existing septic tank is old, cracked, or overflowing. The disposal field has failed and wastewater is surfacing on the ground, creating a health risk.
Minor Dwelling or Sleepout Addition
You are adding a minor dwelling or sleepout to your rural property and need to upgrade or extend the existing septic system to handle the increased load.
Subdivision Creating New Rural Lots
A rural subdivision is creating new lots outside the sewer network. Each lot needs its own on-site wastewater system designed to meet council consent conditions.
Council Compliance Notice on Existing System
Auckland Council has issued a notice requiring you to upgrade your on-site wastewater system to meet current standards. You need a compliant replacement installed.
Difficult Soil Conditions for Disposal
Your property has heavy clay or poor-draining soil that limits disposal field performance. You need an aerated treatment system with a designed land application area.
Converting Shed or Building to Habitable Space
You are converting a farm building or shed into liveable space and need to install a new on-site wastewater system to service the plumbing fixtures being added.
Rural Commercial Premises Without Sewer
A rural commercial property such as a cafe, workshop, or childcare centre needs an on-site wastewater system sized to handle commercial flow volumes and usage patterns.
Our Process
Our Septic System Installation in Auckland Process
Blake Civil Construction follows a systematic approach for every septic system installation in auckland project.
Site Assessment and Soil Testing
We visit your property, assess the ground conditions, and carry out soil percolation tests to determine how your soil absorbs treated wastewater.
System Design and Sizing
Based on soil test results and household size, we design the right system — septic tank or aerated treatment — with a disposal field matched to your site.
Council Consent Application
We prepare and lodge the on-site wastewater consent application with Auckland Council, including site plans, system specifications, and percolation test results.
Excavation and Tank Installation
Once consent is granted, we excavate the tank pit, install the treatment tank on a prepared base, and connect all inlet and outlet pipework.
Disposal Field Construction
We build the disposal field or land application area — laying distribution pipes in gravel-filled trenches designed to disperse treated effluent into the ground.
Commissioning and Council Sign-Off
The completed system is tested, commissioned, and inspected by Auckland Council. We hand over all documentation and operating instructions for ongoing maintenance.

Why Choose Us
Why Choose Blake Civil for Septic System Installation in Auckland?
Licensed Drainlayers on Every Installation
All septic system work in New Zealand must be carried out or supervised by a licensed drainlayer. Our team holds current licences from the Plumbers, Gasfitters and Drainlayers Board, so every installation meets legal requirements and passes council inspection.
System Matched to Your Soil Conditions
We carry out soil percolation testing on your property before designing the system. This determines whether a traditional septic tank or an aerated treatment system is the right fit, and how the disposal field needs to be built for your specific ground conditions.
Full Council Consent Management
Auckland Council on-site wastewater consents require detailed documentation — site plans, soil test data, and system specifications following TP58 guidelines. We prepare the full application and manage the consent process through to approval.
Rural Auckland Ground Knowledge
From Coatesville clay through to Kumeu sandy loam and Helensville alluvial soils, we install septic systems across Auckland's rural areas every week. Knowing how each soil type behaves means we get the disposal field design right from the start.
Traditional and Aerated Systems Available
We install both traditional septic tanks with gravity-fed disposal fields and modern aerated treatment systems for properties where soil conditions or lot size require a higher level of wastewater treatment before discharge to ground.
One Contractor From Start to Finish
Site testing, system design, consent application, excavation, tank installation, disposal field construction, and council sign-off — all managed under one contract with one point of contact throughout your project.
