What Makes Septic Tank Safe Products Different?

Septic tank systems play a crucial role in homes and businesses across Aotearoa. Keeping them running smoothly isn’t just about regular maintenance, it also means paying attention on the products you use, and how often and in what way you use them.

Septic Tank Safe Products

These are specially formulated to:
Avoid killing beneficial bacteria: Septic systems rely on bacteria to break down waste. Harsh chemicals can disrupt this process.
Be biodegradable: They break down naturally and don’t accumulate in the tank or leach field.
Low or no phosphates and surfactants: These can pollute groundwater and harm the environment.
pH-balanced: They maintain a neutral pH to avoid damaging the tank or pipes.

Note: Even if labeled septic-safe, these products may still be unsuitable for non-conventional septic tank systems such as worm farm septic systems also known as vermifiltration systems and composting systems as these are much more sensitive to chemicals. Choose natural, non-toxic, and biodegradable options that are gentle enough for bacteria, worms and microbes.

Regular Products

These often contain:
Bleach, ammonia, or antibacterial agents: These kill bacteria including the good ones in your septic tank.
Harsh solvents and synthetic chemicals: These can clog or corrode pipes and harm the tank’s function.
Non-biodegradable ingredients: These can build up and cause blockages or environmental damage.

Why Use Septic-Safe Products?

Prevent costly repairs or pump-outs: Harsh chemicals can kill the bacteria that break down waste, leading to clogs, backups, and expensive maintenance.
Protect groundwater and the environment: Non-biodegradable ingredients and toxic substances can leach into the soil and contaminate nearby water sources.
Extend the life of your septic system: Gentle, biodegradable products help maintain the natural balance in your tank, reducing wear and tear over time.
Support eco-friendly living: Many septic-safe products are also better for your health and the planet, often made from plant-based or natural ingredients.
