Why Should You Maintain the Septic Tank?

For many Australians, particularly those living in rural areas or on larger properties, a septic tank system is an essential part of their home’s wastewater management. Septic tanks play a crucial role in breaking down and treating wastewater from toilets, showers, and sinks before it’s released into the environment. However, just like any other system in your home, a septic tank requires regular maintenance to function effectively and prevent costly problems. In this comprehensive plumber Perth guide, we’ll delve deeper into the reasons why maintaining your septic tank is essential and provide some helpful tips for homeowners.

Protecting the environment 

A properly functioning septic tank helps protect the environment by treating wastewater before it reaches groundwater, rivers, or creeks. When a septic system is well-maintained, it efficiently breaks down and neutralises harmful bacteria, pathogens, and pollutants. The process involves a combination of physical, chemical, and biological processes that separate and decompose solid waste and treat the liquid effluent. 

However, if the tank is not maintained, it can overflow or leak, contaminating nearby water sources and posing a threat to local ecosystems. Overflow and leakage can result from blockages, excessive sludge buildup, or damage to the tank or drain field. This contamination can negatively impact aquatic life, vegetation, and wildlife, as well as contribute to water pollution.

Preventing health hazards 

A poorly maintained septic tank can cause unpleasant odours and create a breeding ground for harmful bacteria and disease-carrying insects, such as mosquitoes and flies. Moreover, if untreated wastewater contaminates nearby water sources, it can lead to serious health problems for both humans and animals. Contaminated water can cause gastrointestinal illnesses, skin infections, and other diseases, especially if used for drinking, cooking, or bathing. 

By maintaining your septic tank, you can prevent the spread of illness and ensure a safer environment for your family and neighbours. Regular inspections and pumping, as well as proper waste disposal practices, can help keep your septic system in good working order and minimise health risks. 

Avoiding costly repairs 

Regular maintenance of your septic tank can help you avoid expensive repair or replacement costs in the long run. When a septic system is neglected, it can lead to blockages, backups, and even system failure. The signs of a failing septic system may include slow-draining sinks or toilets, sewage odours, soggy ground around the drain field, or wastewater backing up into your home. 

Repairing or replacing a septic system can cost thousands of dollars, so investing in routine maintenance is a cost-effective way to protect your property and save money. Early detection of issues can help you address them before they escalate into more significant problems that require extensive repairs or replacement.

Prolonging the life of your septic system 

Proper maintenance can significantly extend the life of your septic tank and drain field. Septic tanks are designed to last for many years—often between 20 and 30 years—but without regular maintenance, their lifespan can be dramatically reduced. By taking care of your septic system, you can avoid premature replacement costs and enjoy the benefits of a well-functioning system for longer. 

Increasing property value 

A well-maintained septic system is an asset to your property. Prospective buyers are more likely to be interested in a home with a properly functioning septic system, as it indicates responsible homeownership and reduces the risk of expensive repairs or replacements in the future. By investing in regular septic tank maintenance, you can increase your property’s value and appeal, making it easier to sell when the time comes. 

Tips for maintaining your septic tank 

Schedule regular inspections: Have your septic tank inspected by a professional every 3 to 5 years to ensure it’s working correctly and identify any potential issues. These inspections can help detect early signs of problems, such as cracks, leaks, or excessive sludge buildup, allowing you to address them before they become more significant and costly. 

  • Pump the tank regularly: Depending on the size of your tank and the number of occupants in your home, you should have your septic tank pumped every 3 to 5 years to remove solid waste and prevent blockages. Regular pumping helps maintain the efficiency of your septic system and ensures that solid waste doesn’t overflow or clog the drain field. 
  • Be mindful of what goes down the drain: Avoid flushing non-biodegradable items, such as baby wipes, sanitary products, or plastic items, as they can cause blockages in your septic system. Additionally, refrain from disposing of harsh chemicals, such as paint, solvents, or excessive amounts of grease and oil, down the drain, as they can disrupt the bacterial balance and harm the system’s functionality. 
  • Conserve water: Reducing water usage can help prevent overloading your septic system. Fix leaks, install water-saving devices, such as low-flow toilets and showerheads, and spread out laundry loads to reduce the strain on your septic tank. Practising efficient water use not only benefits your septic system but also contributes to water conservation efforts in Australia. 
  • Maintain the drain field: The drain field, also known as the leach field or soakaway, is a crucial component of your septic system that disperses the treated effluent into the soil. To keep your drain field functioning properly, avoid driving or parking heavy vehicles on it, as this can cause compaction and damage to the pipes. Additionally, don’t plant deep-rooted trees or shrubs near the drain field, as their roots can grow into and damage the pipes. 
  • Educate your household: Ensure that everyone in your home understands the importance of septic system maintenance and is aware of the do’s and don’ts when it comes to using and maintaining the system. By educating your household members, you can prevent unintentional damage and keep your septic tank functioning efficiently. 

Why should you consider a septic tank to sewerage conversion? 

As urbanisation continues and infrastructure expands, many areas that previously relied on septic systems now have access to municipal sewerage systems. In such cases, homeowners might consider converting their septic tank system to a connection with the public sewerage network. Below are the potential benefits doing so can offer:

  • Enhanced reliability: Municipal sewerage systems in Western Australia are professionally managed and maintained by local authorities, such as the Water Corporation, ensuring a consistent and reliable service. Converting to a sewerage connection reduces the likelihood of system failures, blockages, and other issues commonly associated with septic tanks, providing homeowners with peace of mind. 
  • Reduced maintenance requirements: Septic tank systems require regular inspections, pumping, and maintenance to function efficiently and prevent problems. By converting to a sewerage connection, you can eliminate the need for these tasks, saving time and effort. The responsibility for maintaining the sewerage infrastructure shifts to the local authority, allowing you to focus on other aspects of homeownership. 
  • Increased property value: A connection to the municipal sewerage system can be seen as a valuable asset for potential buyers, potentially increasing the value and marketability of your property. Prospective buyers may view a property connected to the sewerage network as more desirable, as it indicates a lower likelihood of future issues and reduced maintenance requirements. 
  • Environmental benefits: While well-maintained septic systems can be environmentally friendly, a poorly maintained or failing septic tank can result in contamination of groundwater, soil, and nearby water sources. By converting to a sewerage connection, you contribute to a more centralised wastewater treatment system, which can better manage and treat wastewater on a larger scale, ultimately protecting the environment. 
  • Expanding infrastructure: As Western Australia continues to develop, there may be government or local authority initiatives encouraging septic tank to sewerage conversions in specific areas. These programmes may offer financial incentives, subsidies, or assistance, making the conversion process more accessible and affordable for homeowners. 
  • Improved health and safety: A properly functioning septic system poses minimal risks to health and safety. However, failing septic systems can cause unpleasant odours, attract pests, and lead to contamination of nearby water sources, posing health risks to both humans and animals. Connecting to a public sewerage system can help mitigate these risks, creating a safer environment for you and your community.
