Department of Utility Networks

Utilities are networks before they are assets: a treatment works, a pumping station, a mobile mast and a cable landing each matter for what depends on them downstream.

Wellington and its harbour: a flat plan of the faculty twin. Terrain 0 to 523 m; 83,815 buildings in the box; 5,085 footprints in the core, 2,796 with an estimated height; Roads 176 km; Rail 99 km; 57 substations; 4 port; 2 airport; 5 hospitals; 8 railway stations; 4 water works; 2 power plants, 202 MW. Contours every 100 metres from the elevation grid; buildings as counts per cell; roads and rail by class; lifeline assets as marks; power plants as marks.
Wellington and its harbour, New Zealand. Flat plan of the same data. The 3D twin opens on devices that can draw it, once its data and code have been checked; the numbers are the same either way.

08Questions

Questions, answers and key terms

Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the department's courses?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.

Key terms

Term

Water and wastewater systems

This area covers drinking water supply, distribution networks, wastewater collection and treatment as engineered infrastructure: their hydraulics, asset condition, dependencies on power and chemicals, and the hazards that disrupt them.

Term

Telecommunications and digital infrastructure

This area covers the physical networks of the digital economy: access and mobile networks, backbones, subsea cables, internet exchange points and data centres, and their dependence on power, timing and repair capacity.
