Our Mission
Our Core Principles
Sector Experience Matters
We are lifelong water professionals with sector specific experience and a comprehensive understanding of water assets and infrastructure projects.
Proven Team, Proven Results
Our team consists of trusted professionals who have delivered successful outcomes across the whole project lifecycle.
Long term Relationships
SUMO brings a strong network of relationships and partnerships across local, national, and the international water supply chain — enhancing knowledge, capacity and the ability to innovate on your projects.
Focusing on Critical Tasks
We know what matters and we prioritise our effort. We effectively prioritise the effort of the teams we work with to meet your project’s objectives.
We Plan Effectively
The foundation of successful project delivery is planning. For complex multidisciplinary projects, we build it three times on paper, to build it once on site.
Top-Down Insight, Bottom-Up Detail
Our sector experience allows us to validate from the top-down while developing from the bottom-up. We use benchmarking and an “outside-in” perspective to challenge assumptions and strengthen internal project thinking.
Proactive Risk Management
We understand that risk in water projects can compound and escalate quickly across disciplines and packages. Our team anticipates and actively manages risk to preserve project outcomes.
Strong Stakeholder Relationships
We build collaborative, positive relationships with all stakeholders. Our broad perspective allows us to engage meaningfully, foster alignment, and find mutually beneficial outcomes that embody shared success.
