RISEN is a Marlborough-based engineering practice working across civil, wastewater, and surveying projects. A limited number of projects are taken on at a time to keep things focused, flexible, and well-managed. The approach is grounded in clear communication, practical design, and solutions that work with the land—not against it.
From on-site wastewater systems and flood assessments to drone surveys and catchment modelling, each project is handled with care and a clear understanding of what’s needed on the ground. It's all part of helping good ideas take flight
A) Wastewater Solutions, Marlborough
Tough soil and site conditions called for a smarter approach.
We designed a secondary treatment system with drip line irrigation, set on a slope for natural drainage, with mulch and native planting to boost performance and blend into the landscape. To take it further, we introduced tiger worms for effluent treatment—a low-maintenance, eco-friendly solution that cuts down on mechanical components while maximising waste breakdown. Simple, effective, and built to work with the land—not against it.
B) Drone survey for a developer in Marlborough
Precision matters.
In Marlborough, RISEN Consultancy uses RTK-enabled drones to deliver accurate volume calculations and site assessments. On a recent project, we measured spoil volumes with pinpoint accuracy, giving the client a fixed price and clear timeframe for removal—cutting out guesswork and keeping everything on track. Our drone surveys are a game-changer for quarries, earthwork contractors, and developers, providing reliable data for volume verifications, site planning, and more. Fast, accurate, and built for better decisions.
C) Catchment analysis and culvert design in Marlborough
Huge flows need smart solutions.
In Marlborough and across NZ, managing stormwater isn’t optional—it’s critical. Roads, buildings, and infrastructure rely on systems that handle heavy, frequent runoff without fail. That’s where we come in. At RISEN, we use 3D stormwater design to map catchments and culverts with precision, providing a clear, visual approach that helps clients and stakeholders see exactly how a system will perform before the first pipe goes in. From catchment and flow analysis to culvert design, sizing, and roading realignment, we deliver resilient, data-driven solutions that make stormwater management simple, effective, and built to last.
