“We have had no issues since the unit was installed and that is testament to the design of the unit and the project management provided by Ecocycle.” Thames Coromandel District Council

All wastewater treatment systems need on-going maintenance, including Council reticulated systems and on-site wastewater treatment systems.

When correctly used and well maintained your Ecocycle wastewater treatment system will give you years of trouble-free operation.

Just like your car or ride on mower routine maintenance is essential to optimise the performance of your system, increase the lifespan of the product and reduce effects on the environment.

We offer maintenance services for all our systems and can send you reminders when your six-monthly or annual maintenance check is due.  We can also help with emergencies if your system alarm is activated.

For commercial or community systems we can install a remote monitoring system so we can monitor your system all year round in conjunction with regular maintenance visits.

Looking after your wastewater treatment system

What you put down your drain will impact how much maintenance your system will need.

Alongside six-monthly or annual maintenance services (depending on system type) it is important that you follow some simple do’s and don’ts for the smooth operation of your wastewater treatment system.

This not only protects your system but helps protect the environment too.

The good

  • Be water smart and conserve water. Excessive water use reduces the retention time in your wastewater treatment system and could overload the irrigation to land.
  • Use biodegradable soaps and cleaners and wherever possible use phosphate free or low phosphorus based laundry detergents.
  • Check your cleaning products to see if they are suitable for your wastewater system. [Check out our list of environmentally friendly or natural cleaning solutions here]
  • Scrape all plates and dishes to remove as much fat and grease as possible. A tip is to wipe them with paper towels and place paper towels in the rubbish bin.
  • Quickly fix any leaky taps as soon as possible.
  • Ensure a good vegetative cover is maintained in the area of your irrigation system. We can advise what plant and vegetation is best. Wherever possible we recommend native plants.
  • Direct all surface water and landscaping away from the tank and irrigation system, including roof drains and lawn sprinklers.

The bad

  • Remember never pour toxic or strong chemicals or cleaners down any drains. This includes bleach, fuels, paints, thinners, grease, oil, chemical drain cleaning products, weed or insect killers, drugs, chlorine cleaners or disinfectant based products.
  • Don’t use large amounts of cleaning products.
  • Don’t empty large quantities of water into the system all at once, such as from swimming and spa pools.
  • Don’t let rainwater into the system.
  • Don’t flush solids down the toilet other than standard toilet paper. Onsite wastewater treatments systems are not designed to handle cigarette butts, wet wipes, paper towels, nappies, feminine hygiene products, dental floss, bandaids, etc.
  • Don’t wash all your laundry in one day.
  • Don’t put coffee grinds or tea bags down the sink.
  • Keep vehicles or livestock away from the land irrigation system.

System friendly cleaning products

You should be proud that you have chosen an environmentally friendly wastewater treatment system that exceeds council regulations.

All onsite wastewater treatment systems and septic tanks rely on naturally occurring bacteria in the system to breakdown waste.  Some cleaning products can interrupt this bacteria.

To protect your system and the environment it is important that you choose cleaning products suitable for onsite wastewater treatment systems.

You can find a large range of biodegradable, septic tank friendly products at any grocery store.  Just look out for the eco-friendly and biodegradable tick.

There are also a number of suitable products you can purchase  in bulk online.

And for those who personally like to avoid the use of all chemicals, here is a sample of a few simple ideas to try:



Bio-Zyme offer a range of extremely cost effective environmentally friendly cleaning and deodorising products. We highly recommend and endorse these products to all of our clients (you can even order them from us!). Bio-zyme is organic, non-toxic and biodegradable, but more than this it actually provides a catalyst for the natural treatment of wastewater and waste breakdown. Suitable for households and businesses.

Natural home-made cleaning solutions

Search online for natural homemade cleaning remedies that use baking soda, vinegar and lemon. You will be amazed at how effective they are to use around the house.   Not only are they better for environment, you’ll be surprised at how much money you will save.

Here are some simple ideas to get you started:

  • Baking soda is a versatile, natural cleaning option. For general cleaning sprinkle baking soda on a damp sponge.  Or mix  4 tablespoons baking soda to 1 litre warm water and pour into a spray bottle.  You can even use baking soda to clean the toilet.  Sprinkle it around the bowl and scrub with a toilet brush.
  • For windows, use a solution of 2 tablespoons white vinegar to 1-litre of water. Place the mixture into a spray bottle.
  • To clean your brass and copper scrub them with a half a lemon dipped in salt.
  • An alternative way to clean your oven is to sprinkle salt on the drips and then apply elbow grease. For older spills use baking soda and scouring pads.
