Drainage Systems in Auckland
Blake Civil Construction designs and builds drainage systems in Auckland for residential, commercial, and rural properties. From waterlogged sections on heavy clay through to large-scale subdivision drainage infrastructure, we install subsoil drains, channel drains, soak pits, and combined gravity-fed systems that move water off your property and keep it dry year-round.
What is Drainage Systems in Auckland?
A drainage system is a network of pipes, channels, and soakage devices designed to collect and redirect water away from buildings, foundations, and land surfaces. In Auckland, where heavy Waitemata clay dominates most sections and annual rainfall exceeds 1,200mm, a well-designed drainage system is the difference between a dry, stable property and one that floods every winter. We design each system around your site's specific soil type, slope, water table level, and council requirements — then build it with licensed drainlayers using materials rated for New Zealand conditions.
- Subsoil drainage systems with perforated pipe, geotextile fabric, and gravel trenches for waterlogged sections
- Channel drain installation for driveways, patios, retaining walls, and hardstand areas
- Soak pit design and construction for on-site stormwater disposal in clay ground
- Combined gravity-fed drainage systems linking subsoil, surface, and stormwater networks
- Drainage system design for new builds, subdivisions, and existing properties with water problems
- Full council consent management, inspections, and sign-off for all drainage system installations
Based in Coatesville, Blake Civil Construction installs drainage systems across Auckland's North and Northwest every week. Our licensed drainlayers understand how Auckland's clay soils, steep terrain, and high rainfall interact — so the drainage system we build for your property works when it matters most.
When You Need Us
When You Need Drainage Systems in Auckland in Auckland
Waterlogged Section After Every Rainfall
Your lawn and garden turn into a swamp after rain because the clay soil holds water. A subsoil drainage system collects and redirects the trapped groundwater.
Surface Water Flooding Across a Driveway
Rainwater runs across your driveway and pools at the garage or front door. Channel drains installed at the right fall intercept surface water before it reaches buildings.
Retaining Wall Showing Hydrostatic Pressure Damage
Water building up behind your retaining wall is pushing it forward. Subsoil drains behind the wall relieve hydrostatic pressure and protect the structure long-term.
New Build Needs Full Site Drainage Design
Your new home needs a drainage system designed from scratch — subsoil drains, stormwater connections, and surface drainage integrated into the building plans.
Existing Home with No Subsoil Drainage Installed
Your older home was built without subsoil drains and now the foundations are damp. Retrofitting a perimeter drain system around the footings redirects groundwater away.
Rural Property with Boggy Paddocks and Wet Ground
Paddocks and access tracks stay wet for months because the clay underneath holds water. Agricultural subsoil drainage systems lower the water table and firm up the ground.
Patio and Outdoor Area Pools Water After Rain
Your paved patio or entertaining area collects water because the surface drains toward the house. Channel drains and regrading fix the fall direction permanently.
Subdivision Needs Drainage Infrastructure for Multiple Lots
A new subdivision requires coordinated drainage systems across every lot — subsoil drains, stormwater mains, and on-site disposal designed to meet council requirements.
Our Process
Our Drainage Systems in Auckland Process
Blake Civil Construction follows a systematic approach for every drainage systems in auckland project.
Site Assessment and Soil Evaluation
We inspect your property, assess the soil type and water table, identify where water collects, and determine the right drainage system approach.
Drainage System Design
We design the system layout — pipe routes, fall gradients, drain types, and disposal points — matched to your site conditions and council requirements.
Council Consent and Approvals
We prepare and lodge the required building consent or resource consent applications with Auckland Council and manage the approval process.
Trenching and Pipe Installation
Our crew excavates trenches, lays perforated pipe in gravel bedding with geotextile fabric, and installs channel drains and soak pits as designed.
Connections and System Integration
We connect the drainage network to stormwater outlets, soak pits, or council mains — linking subsoil, surface, and stormwater systems into one working network.
Testing, Backfill, and Sign-Off
We test the system for flow and capacity, backfill trenches, reinstate surfaces, and arrange council inspection for final sign-off.

Why Choose Us
Why Choose Blake Civil for Drainage Systems in Auckland?
Licensed Drainlayers on Every Job
All drainage work in New Zealand must be carried out by a licensed drainlayer under the Plumbers, Gasfitters and Drainlayers Board. Every drainage system we install is built and signed off by licensed professionals — meeting legal requirements and passing council inspection.
Designed for Auckland Clay Soils
Auckland's heavy Waitemata clay barely absorbs water. We design drainage systems specifically for clay ground — using the right pipe grades, gravel bedding depths, geotextile wrapping, and fall gradients that work in conditions where standard drainage fails.
Full System Approach
We design drainage systems as complete networks — not isolated drains. Subsoil drains, channel drains, soak pits, and stormwater connections all work together as a single gravity-fed system that handles water from every source on your property.
Civil Construction Capability
As a civil construction company with excavators, trucks, and earthmoving equipment on hand, we handle the full scope of drainage system installation without needing to subcontract the heavy work. Trenching, excavation, and reinstatement are all done in-house.
Council Consent Management
Drainage systems in Auckland require building consent, and some sites need resource consent as well. We manage the consent process from application through to final inspection — keeping your project compliant and avoiding delays from failed inspections.
Local Knowledge, Local Team
Based in Coatesville, we install drainage systems across North Auckland and the wider region every week. We know the soil conditions in Dairy Flat, the water table issues in Kumeu, and the clay behaviour across the Hibiscus Coast — local knowledge that gets the design right first time.
