How the use of biodegradable products benefits your septic tank’s performance

The delicate ecosystem of your septic tank

What happens inside the pit?

A septic tank works thanks to a set of bacteria and enzymes that transform organic waste into harmless by-products: water, carbon dioxide and inert matter. These micro-organisms are extremely sensitive to:

• Strong antiseptics and disinfectants.

• Phosphates and bleaching agents.

• Solvents and petrochemicals.

When these microbial communities are washed away by domestic effluent, the accumulation of solids and fats is triggered, increasing the risk of clogging and odours.

The role of bacteria

Without an active microbial population:

• Digestion of waste is slowed down.

• Sludge increases on the bottom.

• The solution is costly and frequent emptying of septic tanks that you could otherwise space out.

Biodegradable products: what makes them different?

Environmentally friendly ingredients

The biodegradable cleaners are formulated with:

1. Surfactants derived from vegetable oils instead of synthetic chemicals.

2. Enzymes that promote the breakdown of organic matter without harming bacteria.

3. Absence of phosphates and chlorine, elements that destroy septic flora.

Certifications and labels

When choosing products, look for labels such as:

• Ecolabel (EU)

• EPA Safer Choice (EE. UU.)

• Ingredients of 100% natural origin

These certificates guarantee complete biodegradability and low ecological impact.

Practical advantages for your installation

Odour reduction

A healthy septic system does not emit sulphuric or ammonia gases. By keeping the bacteria active, the digestion process is continuous and controlled, eliminating the compounds responsible for the odour.

Fewer network blockages

Grease and debris are efficiently broken down, reducing floating grease and blockages in pipes. With a regular programme of pipe cleaning and unblocking, you can avoid emergency interventions.

Savings on emptying

Savings in emptyingWith less sediment volume, the interval between septic tank emptyings can be reduced from one or two years to three or four years. Each emptying involves labour, waste transport and treatment, which significantly increases the annual cost.

How to integrate biodegradable products into your routine

Direct replacements

• Dishwashing and detergents: choose phosphate-free formulas.

• All-purpose cleaners: opt for those marked ‘fully biodegradable’.

• Hand softeners and soaps: select those that claim to be ‘enzymatic’ or ‘organic’.

Monthly septic additives

There is a range of biological activators on the market that add bacterial booster strains. Simply pour the recommended dose every month down the toilet or drain.

Additional good practices

• Do not pour cooking fats and oils down the sink.

• Avoid pouring pharmaceuticals and concentrated bleaches.

• Schedules walk-in pipe repair checks when you notice leaks or incipient dampness.

Adopting biodegradable products in your home is the most effective way to protect your septic tank and the environment. Here is an action plan:

1. Gradually replace your cleaning products.

2. Add a monthly septic activator to reinforce the flora.

3. Avoid spillage of grease and strong alkalis.

4. It is complemented by professional services of

   • Emptying of septic tanks

   • Pipe cleaning and unblocking

   • Repair of pipes without building work

With these simple steps, you’ll enjoy an efficient septic system with no bad odours, fewer clogs and lighter bills – start taking care of your septic tank today!
