Onsite Wastewater Consent Renewals in Marlborough

If your wastewater consent is coming up for renewal, we can help you get it sorted. RISEN handles the site inspection, engineering assessment and Council application for properties in Blenheim, Picton, the Marlborough Sounds and the wider region.

​

What’s Involved

System Inspection
We’ll visit your property and inspect the treatment tank, filters, pumps and disposal field. We check for wear, damage and maintenance needs, then explain anything that needs sorting before your consent expires.

​

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 your application to Marlborough District Council, including the site plan, wastewater loading certificate, maintenance schedule, inspection checklist and other required documents. We also handle Council’s questions as the application progresses.

​

Upgrade Guidance (if needed)
If your system needs repairs or an upgrade, we’ll explain why and talk through the options. We’ll agree any extra design work with you first and can help with local contractor pricing and coordination if 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 work is charged at hourly rates because each property and system is different. We’ll talk through the likely scope with you and focus on what’s needed for your renewal.

​

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

​

If your system needs more investigation or design work, there may be additional fees. We’ll let you know when that becomes clear and discuss the next steps with you before carrying out extra work.

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.
