About Us
Designing and delivering critical water infrastructure for growing communities.
Bellcon was established in 2018 by David Bell to specialise in water and wastewater project management. Since then, the company has grown with purpose, building a trusted reputation in delivering complex infrastructure.
Civil and Structural Engineer Stephen Abercrombie joined as a partner in 2021. By 2024, the team had expanded to 14, including site engineers, project managers, and experts in process engineering, mechanical engineering and construction.
In 2025, Bellcon opened an Auckland office to support a growing portfolio across the North Island, while continuing to serve clients nationwide from its head office in Northland. That same year, Thomas Board joined as Chief Engineer, strengthening the company’s expertise in advanced water and wastewater treatment plant design.
Bellcon’s services cover the entire project lifecycle, including early contractor involvement, design and build, construction monitoring, project management, design management and commissioning management. We are known for our collaborative approach, technical expertise and ability to help future-proof drinking water, and wastewater systems across New Zealand.
For our clients
We respond quickly, communicate clearly, and work closely with all stakeholders. Bringing a relentless focus on productivity and efficiency is part of everything we do.
From meeting regulatory requirements to improving sustainability, every stage is planned, monitored and documented to keep your project running smoothly.
Our clients trust us to manage additional requests within an agreed framework, with transparent pricing, and a no-surprises approach to budget and risk management.
For the environment
We design systems that go beyond compliance. That means rethinking how wastewater is managed, constantly innovating to reduce environmental impact, and delivering sustainable drinking water solutions that meet the needs of rural towns or growing cities.
For the community
At Bellcon, we are driven by a simple idea: every community deserves safe, reliable water infrastructure to thrive.
We understand the pressure of delivering essential services, and the responsibility of getting it right.
Every site is different, so we work closely with clients and contractors to plan, build, operate, and maintain drinking water and wastewater treatment systems that meet local needs. Our work is built to last and made to serve.
Omanaia Water Treatment Plant
"H&S and Quality risk were well managed, but the highlight for me on this project was the financial risk management. All additional cost variations were actively managed with cost saving proposals to ensure the final project costs did not exceed the available budget".
Marie - Distribution Engineer
Whangarei District Council
"The team had excellent paperwork. The contract responsibilities and activities were effectively managed, exceeding what was stated in the tender submission. The team demonstrated excellent planning and execution throughout the project, including the project being completed within budget."
Dirk - Senior Project Manager
Watercare Services Ltd
"Challenges were solved quickly and pragmatically which demonstrated the high skills level of Bellcons management and experience. Timelines were improved on the agreed schedule which reduced Watercare’s tunnelling project’s risk drastically. No deliverable deficiencies were recorded, and compliance statements were issued immediately after works completion.".

Management went above their contractual responsibilities in how they dealt with issues and risks. Really high knowledge of the contract works, extremely technically savvy with the requirements and very polite and humble to deal with. Their technical capabilities saved us a lot of additional design work and equipment re-specifications.
Cutting edge technology
At Bellcon, we specialise in delivering exceptional water and wastewater projects. Utilising technology and our team's engineering expertise, we ensure efficiency, precision, and excellence at every stage of the design and construction process.
Design
Bellcon harnesses the power of Autodesk Plant 3D to streamline the design processes of complex water and wastewater treatment facilities. Our engineers utilise the comprehensive tools and intelligent models to create detailed 3D representations of equipment, piping, and structures, enabling spatial planning, identifying potential clashes, and ensuring seamless integration of various components.
Plan
When facilitating coordination and collaboration among stakeholders in the design and construction phases, Bellcon uses Navisworks for project review and coordination, enabling the integration of multidisciplinary models, allowing for clash detection, visualisation, and coordination across various disciplines.
Build
During the construction phase, Bellcon relies on Autodesk Advance Steel to transform design intent into precise fabrication and erection drawings for structural components. The advanced modeling allows our engineers to generate detailed steel structures efficiently, ensuring total compliance in line with industry standards and regulatory requirements.
