About Us
At Taranaki Wastewater Design we specialise in septic and stormwater system design with a difference, practicality first.
Our company was founded out of frustration with conventional engineering designs that often failed to meet practical installation requirements. Falls, depths, and site realities are all too often overlooked but that’s where our hands-on experience comes in.
We provide a full-service solution: from initial design, through installation via our trusted installation arm, Evergreen Plumbing, and ongoing maintenance to ensure your system performs reliably for years to come.
With a focus on practical, reliable solutions, we’re here to make sure your septic and stormwater systems are designed right the first time and continue to work as intended well into the future.
Our People
Our team of three qualified designers, Chris, Kelvin, and Sam are not only certified in NZQF 4216 Onsite Wastewater Management System Design, but also Certified Plumbers and Drainlayers. This unique combination means we don’t just design systems that look good on paper; we design systems that actually work in the real world.
