Denver Water
Denver Water serves 1.4 million people in the City and County of Denver, Colorado, and a portion of its surrounding suburbs. Established in 1918, the utility is a public agency funded by water rates and new tap fees, not taxes. It is Colorado's oldest and largest water utility. Overview. Denver Water's primary water sources are the South Platte River, Blue River, Williams Fork and Fraser River watersheds, but it also uses water from the South Boulder Creek, Ralston Creek and Bear Creek watersheds. History. The first residents of the Denver area drank water directly from the  creek and river. Surface wells and buckets of water sufficed for a while as a delivery system, but they soon proved inadequate. Irrigation ditches were the next step forward. In 1870, when the rapidly growing community had a population of almost 5,000, the Denver City Water Company was formed. In 1872, with a large well, a steam pump and four miles (6 km) of mains, Denver City Water Company began to provide water to homes. Over the next two decades, 10 water companies fought, collapsed or merged. Several companies merged, and in 1894, the Denver Union Water Company—predecessor of  Denver Water—emerged to establish a stable system. In 1918, Denver residents voted to form a five-member Board of Water Commissioners and buy the Denver Union Water Company's water system for $14 million, creating Denver Water. From that time on, Denver Water planned and developed a system to meet the needs of the people of Denver and the surrounding areas. Flash floods between 1996 and 2002 led to erosion and damage to Denver's reservoirs. This erosion were exacerbated by the insects and disease in the 1990s that had weakened forests. To address this, Denver Water began  replanting mountainsides with drought-resistant trees in order to better maintain its waterways. Lead service pipes. Lead pipes were used to hook homes to water mains until the World War II era; they were banned in 1971. "Utility spokesman Travis Thompson said Denver Water’s service area was left with between 64,000 and 84,000 homes with lead service lines." A $500 million program to replace them is proceeding as of 2021 at the rate of about 5,000 homes a year. Whether a particular address has a lead service line may be searched for on a page on the Denver  Water website.
