Waste Water

Trade wastewater refers to any liquid from commercial or industrial premises that has been discharged. The process of managing trade wastewater correctly is incredibly important, by following the right protocol you will help prevent:

  • Sewer blockages or spills

  • Damage to the wastewater system

  • Health hazards for people

  • Harm to the environment

This is where E&I comes in! We are consultants for trade wastewater and help businesses understand their obligations as well as containing and disposing of businesses wastewater so that it doesn't end up in the stormwater system.

Consent From The Council

Prior to discharging any trade wastewater you must get consent from the local Council.


This consent form will go into detail about the amount of wastewater that can be discharged, the types of substances allowed in the wastewater, any pre-treatment, servicing requirements and annual costs.

Factory Waste Water Irrigation


Industrial wastewater varies considerably depending on the type of industry.


In many cases local councils require pre-treatment or complete on-site treatment of wastewater.


E&I can help design a wastewater treatment system to get you the compliance tick.  

We take a holistic view of your factory site and design a system that works for your business.

Waste Water Irrigation

Wastewater irrigation, like effluent irrigation, is an economic practice that had been around for decades in many developed countries around the world. 


However there are risks with wastewater irrigation, as it may also significantly increase the concentrations of heavy metals in the soil.   We can work with you to design a safe system that will help treat your waste water so that it does not damage the environment or pose any health risks.   Contact us today to talk about how we can work with you, projects we have already worked on of if you have any questions. 


Stock Truck Effluent Design & Management


Effluent spilling onto roads from stock trucks is a long-standing and significant problem in New Zealand

These spillages pose safety and health threats to road users and damage to roads and the environment through run-off.

Stock truck effluent first came to the attention of authorities in March 1992 when a motorcyclist died after his bike skidded on effluent discharged from a stock truck.

We can help both operators and councils with their stock truck waste and disposal systems.  

Contact us today to chat about how we can help.
