In July 1799 Owen and his partners bought the New Lanark mill from David Dale, and Owen became the New Lanark mill's manager in January 1800. Encouraged by his success in the management of cotton mills in Manchester, Owen hoped to conduct the New Lanark mill on higher principles than purely commercial ones. David Dale and Richard Arkwright had established the substantial mill at New Lanark in 1785. With its water power provided by the falls of the River Clyde, the cotton-spinning operation became one of Britain's largest. About 2,000 individuals were associations with the mill; 500 of them were children who were brought to the mill at the age of five or six from the poorhouses and charities of Edinburgh and Glasgow. Dale, who was known for his benevolence, treated the children well, but the general condition of New Lanark's residents was unsatisfactory. Over the years, Dale and his son-in-law, Owen, worked to improve the factory workers' lives.  Many of the workers were in the lowest levels of the population; theft, drunkenness, and other vices were common; education and sanitation were neglected; and most families lived in one room. The respectable country people refused to submit to the long hours and demoralising drudgery of the mills.  Until a series of Truck Acts (1831-1887) required employees to be paid in common currency, many employers operated the truck system that paid workers in total or in part with tokens. The tokens had no monetary value outside the mill owner's "truck shop," where the owners could supply shoddy goods and charge top prices. In contrast to other employers, Owen's store offered goods at prices slightly above their wholesale cost. He also passed on the savings from the bulk purchase of goods to his workers, and placed the sale of alcohol under strict supervision. These principles became the basis for the cooperative shops in Britain, which continue in an altered form to trade today.
