摘要

Underground. It's not a subject which many people think about - unless they work in a networks or the transport business. However, when roadworks spring up on the daily commute, or an essential utility supply is interrupted to a home or business, customers' thoughts do jump to their utility providers. The truth is that it's busy underground with complex networks of gas, water, wastewater, communications and electrical conduits, including the transport network in London.
