Living with a septic tank system is part of everyday life for many households in Christchurch and throughout rural New Zealand. These systems are essential for safely treating and disposing of wastewater when properties aren’t connected to a mains sewer.
If you’ve recently had a septic tank installation in Christchurch or anywhere else in NZ, or are considering a septic tank replacement, it’s important to know how to look after your system properly. With the right habits, a septic tank can last for decades. Without care, you could end up with costly problems and inconvenient repairs.
At Drainpro, we help homeowners and builders across Christchurch, Auckland, Waikato, and Central Otago with new installations, replacements, and ongoing support. Below, we’ve put together some practical do’s and don’ts to help you get the most from your system.

Why Septic Tank Care Matters
A septic tank isn’t something most homeowners think about every day, until something goes wrong. A well-maintained tank will keep your household wastewater moving smoothly, protect your property from leaks and overflows, and ensure compliance with council regulations.
Poor habits, like flushing the wrong items or neglecting regular servicing, can lead to blockages, bad smells, or even system failure. In serious cases, you may need an early septic tank replacement, which is an expense and disruption you’ll want to avoid.
By following some simple guidelines, you can extend the life of your system, reduce risks to your property, and enjoy the peace of mind that comes with knowing your wastewater is being managed correctly.
The Do’s of Septic Tank Living
There are several positive habits that will help your system perform well over the long term.
Firstly, make sure you schedule regular maintenance. Septic tanks need periodic inspections and pumping to remove solids that accumulate over time. Leaving this too long increases the risk of clogs and overflow.
Next, use water efficiently. Spreading out laundry loads, showers, and dishwashing throughout the day helps reduce pressure on the system. A sudden surge of water can overwhelm the tank and push untreated waste through the drainage field.
It’s also essential to be careful about what you put down the drain. Stick to septic-safe cleaning products and avoid strong chemicals that kill off the beneficial bacteria inside the tank. These bacteria are what break down waste and keep the system balanced.
Finally, know the location of your tank and drainage field. Keeping heavy vehicles, construction, or large structures away from the area prevents damage to pipes and underground components.
If you notice anything unusual, like slow drains, gurgling noises, or unpleasant smells, contact a professional drainlayer promptly. Early action usually means a simple fix rather than a major repair.
The Don’ts of Septic Tank Living
Just as important as the good habits are the things you should avoid.
One of the most common mistakes homeowners make is flushing items that don’t break down. Wipes, nappies, sanitary products, and even paper towels can all cause major blockages in a septic system. Only flush toilet paper and human waste.
Another issue is pouring fats, oils, and grease down the sink. These solidify inside pipes and tanks, leading to clogs and costly callouts. Always dispose of kitchen fats in the rubbish instead.
You should also avoid overloading your system with too much water at once. A long shower, dishwasher cycle, and laundry load all happening at the same time can overwhelm the tank. Spread water use across the day where possible.
Large trees and shrubs should not be planted near your tank or effluent field. Their roots naturally seek moisture and can easily break into pipes, creating expensive damage.
Lastly, never ignore warning signs, such as pooling water around the tank area, strong odours, or unusually lush grass growth. These may indicate that your septic tank is failing or close to capacity.
