Onsite Wastewater Consent Renewals in Marlborough

If your onsite wastewater discharge permit is nearing expiry, RISEN can manage the renewal from inspection through to the Council application. Based in Marlborough, we provide clear engineering advice for properties in Picton, the Marlborough Sounds, Blenheim and the wider region.

​

What’s Involved

System Inspection
We’ll visit your site to carry out a full inspection of the system — that includes the treatment tank, filters, pumps, and disposal field. We look for any wear or damage and flag maintenance items early, so you’ve got time to sort things out before your consent lapses.

​

Engineering Assessment
You’ll get a full engineering report prepared by a Chartered Professional Engineer. This checks the condition and performance of the system, confirms soil type, and compares everything against current standards (AS/NZS 1547:2012). It includes a site risk assessment and outlines any actions needed to meet requirements.

​

Consent Application
We prepare and submit the resource consent application to Marlborough District Council on your behalf. That includes all the technical documents — site plan, wastewater loading certificate, maintenance schedule, inspection checklist, and anything else required. We also deal with any questions or follow-ups from Council.

​

Upgrade Guidance (if needed)
If the system is old, poorly installed, or just not working properly, we’ll let you know what’s needed. If extra design work is required, we’ll talk that through with you before doing anything further. We can also point you to local drainlayers and contractors if any upgrade work is needed.

​

What we send to Council

• Site inspection and system review

• Engineering assessment and wastewater report comparing against current standards and guidelines.

• Resource consent application and Assessment of Environmental Effects in line with Council requirements.

• Supporting documents for Council (site plans, certificates, maintenance schedules)

• Follow-up with Council as needed or answer queries.

​

The application is prepared for the current Marlborough District Council requirements that apply to the property and discharge.

 

Our fees

This service is charged at hourly rates because the investigation and Council requirements vary between properties. We keep the work focused on the engineering and application information needed for a complete, practical renewal.

​

For most sites in the Marlborough region, the total fee typically falls between $2,500 and $3,000 + GST.

​

If the system is found to be inadequate or requires further design work, additional time may be needed. If that happens, we’ll let you know as soon as it’s identified and discuss how best to proceed — no unexpected costs.

For remote properties, a modest travel fee may apply. We’ll confirm this upfront if relevant.

​

Marlborough District Council currently lists a $1,332 initial application fee, including GST, for non-notified resource consents other than subdivisions. This is paid directly to Council and is a minimum charge; additional processing costs may apply. Check Council’s current fee schedule before lodging.
