A stinky nuisance: When septic tanks burst

In Malaysia, septic tanks are a lifeline for many households, quietly managing the sewage generated daily. However, beneath the surface lies a ticking time bomb: The possibility of a septic tank burst. This alarming scenario can unleash a host of health hazards, environmental damage and a drastic drop in property value. Ignoring the implications of such an event is a gamble that homeowners and property owners cannot afford to take.

Imagine a septic tank as an inconspicuous underground chamber that performs the vital task of separating solids from liquids. It is designed to channel sewage safely into a drain field away from our homes.

But when disaster strikes and a tank bursts, it is not just a minor inconvenience, it is a crisis in the making. Untreated wastewater, teeming with harmful bacteria and viruses, can spill into the surroundings, transforming a peaceful neighbourhood into a serious health threat.

The immediate aftermath of a septic tank burst can be nothing short of catastrophic. Picture foul-smelling torrents of wastewater seeping into the soil, contaminating groundwater and polluting nearby streams and rivers.

This contamination is a gateway to a host of waterborne diseases: Typhoid, cholera and hepatitis A, to name a few.

Moreover, the aftermath does not stop there. Local flora can wither and aquatic ecosystems can be thrown into disarray.

The repercussions do not fade with time either. Long after the initial chaos, the impact of a burst septic tank can linger like a bad memory.

Contaminated soil becomes a challenge for gardeners, making growth nearly impossible. Deep beneath the surface, groundwater supplies face the threat of pollution, putting drinking water sources at risk.

To top it off, property values can plummet. A once desirable home may turn into a danger zone, leaving potential buyers wary of the lurking health risks and environmental concerns that a septic disaster brings.

Understanding the weight of these implications is not just practical, it is essential for safeguarding not only your home and health, but also the community.

Blowing up headlinesUnder the Water Services Industry Act 2006, all property owners, managers or occupants with septic tanks are required to conduct regular desludging.

Failing to comply with this regulation is considered an offence under subsection 65(3) of the Act, which carries a potential fine of up to RM50,000. In Malaysia alone, there are approximately 1.35 million septic tanks that must be emptied at least once every two years.

Burst septic tanks have caused fatalities in the past. In November 2019, a septic tank cleaner was killed after the tank exploded in East Jakarta.

There was also an incident in Guangxi, China, where a septic tank pipe burst under the road where construction was taking place. The massive eruption of waste flew 10m high and traumatised many.

Another Southern Chinese city of Nanning saw newly installed sewage pipes bursting as well, with a video showing cars and pedestrians covered in both waste and disbelief. The Nanning incident was dubbed “poo-nami” by the media.

Avoid becoming the neighbourhood villainOwning a septic system requires the owner to know the signs of a failing installation, what causes a durable tank to burst and what to do next.

A septic tank usually lasts up to 40 years and the most common cause of septic system failure is inadequate maintenance.

Regular maintenance from qualified professionals is the best way to spot and fix problems before they lead to more expensive damage.

What are some signs that a septic tank needs to be replaced?

The presence of standing water or puddles is a big brown sign to change the tank. Even more so if the puddles have a foul odour like rotten eggs or sulphur and appear in spots around the garden. Standing water usually means the system is struggling to dispose of water or filter it correctly.

On the other hand, a full septic tank can be pinpointed if there is trouble flushing the toilet or if it is constantly backing up. Another telling sign is when the pipes start making a gurgling sound.

Besides that, the property would smell, well, bad.

Big bangBy skipping the maintenance, the owner is essentially setting themselves up for a big explosion in their garden and bank account. The financial implications of a septic tank burst can be substantial.

The cost of cleaning up the contaminated area, repairing the septic tank and potentially replacing the entire system can run into thousands of ringgit.

Additionally, homeowners may be legally liable if the contamination spreads to neighbouring properties or public water supplies.

Early preventionAlthough a septic tank burst can be disastrous, homeowners can reduce the risk by taking certain precautions.

To keep the septic tank from overflowing, routine pumping and inspections are necessary. Depending on the size of the tank and the number of people living in the house, septic tanks should be inspected every two to three years and pumped every three to five years.

Homeowners should also refrain from flushing non-biodegradable items such as paper towels, wipes and feminine hygiene products down the toilet. These things have the potential to harm the septic tank and clog the pipes.

Additionally, it is crucial to refrain from using too much water when doing laundry or dishwashing because this can overload the septic system.

A septic tank burst is a serious matter that can have far-reaching consequences. Contact a septic professional as soon as possible.

The local professionals have the necessary experience, equipment and expertise to wade through the sludge of issues. Besides that, drop a line to the septic system’s manufacturer too.

By taking proactive measures to maintain and inspect septic tanks, homeowners can significantly reduce the risk of such an event.

It is also important to be aware of the signs of a failing septic tank and to address issues promptly. By doing so, homeowners can protect their health, their property and the environment.
