Consent Applications


Natural Resources (and other) Consent Applications

IWS is familiar with Council consenting requirements for industrial and commercial sites, and can assist companies to obtain the appropriate consents or certificates of compliance for their business. These usually involve: 

  • Industrial or Trade Activity Consents (or similar)
  • Stormwater Diversion and Discharge Consents
  • A combination of both.

The consent names, coverage and requirements vary slightly for each region of NZ. The objective of these consents is for the Council to approve the means by which a site will protect the land and water environment over the longer term. These consents ensure a company covers the full range of environmental issues around its site(s) with a view to longer term land and water protection. This includes:

  • Pollution source control – both structural and procedural
  • Understanding and mapping the drainage networks
  • Chemical, oil and fuel control (Environmentally Hazardous Substances) management
  • If required - stormwater treatment design (and installation)
  • Environmental Management Plans and Emergency Spill Response Plans
  • Ongoing stormwater monitoring
  • Staff environmental awareness training

Trade Waste Agreement and Trade Waste Management Plan

Most connections from an industrial or commercial property to the Council network require a trade waste discharge agreement or consent with the local Council or 'wastewater authority' (such as Watercare in Auckland). This plan will identify potential risks to our wastewater system created by your site activities and will detail how these risks will be mitigated.

  • We are experienced in obtaining the information required for these consents, and specialise in applying for them on your behalf
  • One key area of experience is the management of stormwater infiltration where outside work processes have to take place. This might include stormwater diversion or detention systems with delayed release.
  • Where the site cannot comply with consent conditions, IWS will work with the client to find a practical solution and negotiate on your behalf
  • IWS provides trade waste monitoring for its own and other stormwater treatment systems, to meet Council consent compliance and for troubleshooting.
  • More information from Watercare can be found here

Pollution Prevention and Industrial Trade Activity (ITA) 

IWS undertakes land and water pollution prevention audits, often as part of the process in obtaining consents or developing an Environmental Management Plan (EMP), however we also undertake investigation work to determine volumes and flow-paths.

IWS finds it completes most of its auditing work in the area of "coal face" audits – the identification of actual and potential pollution risks. The resultant 'Aspects and Impacts" summary is used to direct the improvements required around a site, and eventually become part of the Environmental Management Plan.

Along with a significant range of industrial site experience, the team auditing skills include:

  • QAS environmental auditing training


Environmental Management Plans

Developing a site Environmental Management Plan (EMP) is a good way of checking that all the risks have been addressed and of providing a means to protect your site and the local environment on an ongoing basis. The Emergency Spill Response Plan (ESRP) is a significant part of the EMP. The focus of the EMP needs to be to staff usability – it needs to work on the factory floor. Any site’s Environmental Management Plan (EMP) need regular updating. This is usually after the site audit when issues may have been identified.
