How to prevent overflows

Together, we can improve the water quality of Auckland’s streams and beaches.

  • We are working hard to reduce overflows in the public network

  • Householders and businesses can also help to protect our networks and the environment. Follow our practical tips to prevent blockages in your plumbing and in public pipes.

Put rubbish in the bin, not down the drain

What you put down your sink or toilet can affect your pipes and our network.

Remember – only human waste and toilet paper should be flushed down the toilet. Everything else – including things such as wipes, sanitary products, dental floss and nappies, and fat, oil and grease from cooking – should be put in the bin.
