Maintaining a well-functioning drainage system is critical for property owners across New Zealand. With the country's high rainfall, flooding rivers, and variable geography, having an effective and maintained drainage system is crucial. Drainage systems that are not properly maintained can lead to flooded properties, erosion, environment pollution, and extensive property damage for Kiwi homeowners. This highlights the importance of regular inspection and proactive maintenance of drainage systems across the diverse regions of New Zealand. Whether you own a home in Auckland, Wellington, Christchurch, or elsewhere in the country, following through on the proper upkeep of your drainage system is an essential responsibility.
This article will provide homeowners and property managers with a helpful overview of drainage system basics, maintenance tips, and reasons why staying on top of drainage system care is so important in the New Zealand climate and landscape. Keep reading to learn what's involved in drainage system maintenance and how to help keep your property and community flood-free.
Drainage systems are designed to remove excess water and moisture from an area or property. They play a critical role in maintaining dry conditions and preventing flooding or water damage. The most common types of drainage systems seen in New Zealand include:
Surface drainage - This removes water that collects on the ground, such as during heavy rainfall. Systems include sloped driveways, drainage channels, and rain gutters that divert water away from a property.
Subsurface drainage - Installed underground, usually using perforated plastic tubing, this drains excess moisture from the soil. It prevents flooding and makes the ground stable. Common in farmlands and sports fields.
Sewer drainage - The underground sewage system takes all the wastewater from toilets, sinks, washing machines, etc. and transports it to treatment facilities. Septic tanks are used in areas without centralized sewer drainage.
Stormwater drainage - Designed to drain and divert the increased surface runoff during heavy rains. May include street gutters, culverts, retention ponds, and pipes leading to streams or the sea. Prevents urban flooding.
Foundation drainage - Installed around the exterior of foundations and basements. Usually a perforated pipe that leads water away from the building's foundation into the storm drainage system. Prevents moisture damage.
The specific type of drainage system installed depends on the geography, landscape, climate and needs of the property or area. Proper drainage is especially crucial in New Zealand due to the wet climate in many parts.
Drainage systems that are not properly maintained can lead to a number of serious issues. Lack of maintenance can result in clogs and backups which lead to flooding, environmental pollution, and damage to property.
One of the key reasons to keep up with regular drainage system maintenance is to extend the lifespan of the system. Like any infrastructure, drainage systems deteriorate over time from normal wear and tear. Regular maintenance helps prevent major issues by keeping the system clear of obstructions, ensuring proper water flow, and monitoring for early signs of problems. Proactively maintaining drainage systems means you can address minor issues before they become major failures or replacements.
Proper drainage system maintenance also improves water efficiency. Clogs and obstructions force water to back up and take alternative paths of drainage. This puts excess strain on certain parts of the system while underutilizing others. With consistent maintenance to clear obstructions, water can flow as intended to make the most efficient use of the drainage infrastructure. Any leaks or cracks compromising flow can also be detected and repaired through routine maintenance.
New Zealand's climate and geography present some unique drainage challenges that require tailored maintenance plans. The country experiences high volumes of rainfall nationwide, with parts of the west coast averaging over 6,500 mm annually. The mountainous terrain in many regions contributes to frequent flooding and erosion issues. Additionally, New Zealand's soils tend to have low permeability, which can impede drainage and lead to pooling or runoff.
Regional differences across New Zealand mean drainage systems face diverse environmental factors. The Auckland area is prone to clay soils and storms that can overwhelm systems. Parts of Canterbury deal with limestone that dissolves to form sinkholes for drainage failures. Areas like Bay of Plenty battle subsidence and soil stability concerns that impact drainage. Understanding localised issues is key to creating an effective maintenance schedule.
With the heavy rains, flood risks and varied soils, regularly maintaining drainage systems takes on heightened importance in New Zealand. Homeowners and professionals alike need to be proactive against the environmental factors facing drainage across different parts of the country. Staying on top of maintenance helps ensure drainage systems are resilient and minimises risks to property or the wider environment.
Homeowners can take several steps to properly maintain their drainage systems and prevent future issues.
Suggested Maintenance Frequency
Inspect your drainage system at least twice per year - before and after winter. Look for any signs of clogging, damage, or leaks.
Clean gutters and downspouts in early spring and fall. Remove any accumulated leaves, sticks or other debris.
Flush underground drains in spring and fall by running lots of water through the system.
Professionally inspect any septic tanks every 3-5 years. Pump out tanks as recommended.
Steps Homeowners Can Take
Visually inspect all drains, pipes, gutters and catch basins around your home. Clear any collected debris like leaves or rocks by hand or with a wet/dry vac.
Use a plumbing snake to clean out slow-flowing floor drains or plumbing vents. Don't use harsh drain cleaners.
Test sump pumps and backflow valves to ensure proper functioning. Clean pump inlets and outlets.
Level any sinking drain covers by raising with sand or resetting the frame.
Patch or replace any cracks, damaged pipes, or poorly draining ditches.
Professional Help for Complex Systems
Hire a qualified technician for camera inspections of underground pipes. Address any intruding roots, cracks or blockages found.
Have professionals assess driveway culverts, french drains, or other landscape drainage. Repair or replace as needed.
For septic systems, only licensed experts should handle major repairs, replacements, or any work requiring a permit.
Seek professional drainage services for recurring problems or complex maintenance beyond a homeowner's abilities.

Maintaining a well-functioning drainage system is critical for property owners in New Zealand due to the country's high rainfall, flooding rivers, and variable geography. Neglected drainage systems can lead to flooded properties, erosion, environment pollution, and extensive property damage. Regular inspection and maintenance helps prevent flooding and costly repairs.
The most common drainage systems in New Zealand include surface drainage like rain gutters, subsurface drainage like perforated tubing to drain soil, sewer drainage to transport wastewater, stormwater drainage like street gutters, and foundation drainage around basements. The systems installed depend on the property's geography, landscape, climate and drainage needs.
Poor drainage maintenance can lead to flooding, foundation damage, mould issues and costly repairs. Clogged drains force water to back up and find alternative routes, putting strain on certain areas of the system. Leaks and cracks also compromise proper water flow. Lack of maintenance shortens the lifespan of drainage infrastructure.
New Zealand experiences very high rainfall totals nationwide that contribute to flooding and erosion concerns. The mountainous terrain also increases runoff issues. Additionally, New Zealand's predominantly clay soils have low permeability, which impedes drainage and leads to pooling or excessive runoff during storms. Understanding these localized issues helps create effective maintenance plans.
Homeowners should visually inspect drains twice yearly, clear any debris, use plumbing snakes to clear clogs, test sump pumps, patch cracks, and clean gutters in spring and fall. For complex repairs like pipe relining, camera inspections or septic work, hiring qualified drainage professionals is recommended.
Hiring qualified drainage professionals ensures repairs meet national standards and building codes. They have specialized technical expertise, advanced equipment for diagnosis and repair, and comprehensive knowledge of best practices.
