Water, for a city like Chicago, is a precious resource, but one-fourth of its pipeline system is nearly 100 years old, and plagued by leaks and breakdowns. That’s why Chicago is updating its water infrastructure as well as its public transport. The city is currently substituting 1,450 kilometres of water pipes and 1,080 kilometres of sewer lines piece by piece so that it can completely replace the current network by 2054. It’s an impressive project because it reduces waste to zero, protects the city from river floods and guarantees efficient management of both drinking water and waste water.
