Utilities such as water, electricity, gas and sewers rely on pipes and cables. With time these
infrastructure age and eventually fail.

Whatever the utility, pipe or cable failures can lead to dangerous situations (sinkholes, electrical fires, gas explosions...) and lots of waste (in terms of money or real waste in the case of sewers).

Anyway, according to the Duke University's Nicholas School of the Environment, natural gas pipes in Washington DC so desperately need maintaining that some manholes are ready to explode, literally:

And while we're at it... next to the danger of explosion, methane is also a greenhouse gas, and it is 25 times more potent than CO2...
