Waste Water

Waste water system

A piped wastewater (sewerage) disposal system is provided in the Ōtorohanga Community.

Wastewater is collected, piped to a treatment facility north of the town and is treated before being discharged to the Mangaorongo Stream.

The wastewater system is provided for the discharge of waste water from toilets, baths, showers, sinks and other such sources.

It is not to be used for:

  • discharge of rainwater from roofs or other hard surfaces, or
  • the disposal of toxic or hazardous substances.

Liquids such as oils and paints and other chemicals must not be discharged to the wastewater system, as they will interfere with the treatment process, potentially resulting in severe pollution.

Should a property wish to discharge material to the Ōtorohanga wastewater system and their discharge material:

  • is significantly different to the 'domestic sewerage' produced by residential properties,
  • has a volume greater than 5 m3 per day,

they must obtain a Trade Waste Consent from Council.

Council does not provide a wastewater disposal system to properties outside of Ōtorohanga.

All other properties in the District must have their own wastewater systems that meet the requirements of the Waikato Regional Council.
