<human>:  Why did the London County Council have a monopoly on the supply of water in London?
<bot>: The London County Council had a monopoly on the supply of water in London from 1855 to 1905. They were given the monopoly because the private companies that provided water to London at the time had not invested enough money in the infrastructure. The council was also given a monopoly on the collection of the water rates, which allowed them to invest in the infrastructure.
