Question: How many kilometers of sewer lines exist in the city that contains the university where Charles Oakley was educated?

<P0-S0> Like two similar players, Charles Oakley before him and Ben Wallace (also undrafted) after him, Davis attended Virginia Union University and made a name for himself as a hard-nosed defensive player and rebounder. <SEP> <P1-S0> He graduated as valedictorian of Waters Training School in Winton, North Carolina, in 1901, and attended Wayland Academy and Virginia Union University in Richmond, Virginia, from 1901 to 1903. <P1-S1> He was born in Ahoskie, North Carolina, the son of Lucy Peoples and an unknown father. <P1-S2> He then attended Western University of Pennsylvania, (now the University of Pittsburgh) and graduated from its law school in 1909. <P1-S3> He passed the bar examination in 1909 and married Jessie Matthews from Gettysburg, Pennsylvania, on February 17, 1919. <SEP> <P2-S0> The wastewater utility also operates and maintains 1,500 miles (2,400 km) of sanitary sewer and pumping stations, 38 miles (61 km) of intercepting sewer lines, and the Shockoe Retention Basin, a 44-million-gallon stormwater reservoir used during heavy rains. <P2-S1> The wastewater treatment plant and distribution system of water mains, pumping stations and storage facilities provide water to approximately 62,000 customers in the city. <P2-S2> There is also a wastewater treatment plant located on the south bank of the James River. <P2-S3> This plant can treat up to 70 million gallons of water per day of sanitary sewage and stormwater before returning it to the river. <SEP> <P3-S0> newtown creek, a 3.5-mile (6-kilometer) a long estuary that forms part of the border between the boroughs of brooklyn and queens, has been designated a superfund site for environmental clean-up and remediation of the waterway's recreational and economic resources for many communities. <P3-S1> one of the most heavily used bodies of water in the port of new york and new jersey, it had been one of the most contaminated industrial sites in the country, containing years of discarded toxins, an estimated 30 million us gallons (110,000 m3) of spilled oil, including the greenpoint oil spill, raw sewage from new york city's sewer system, and other accumulation. <SEP> <P4-S0> european higher education took place for hundreds of years in christian cathedral schools or monastic schools (scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century. <P4-S1> the earliest universities were developed under the aegis of the latin church by papal bull as studia generalia and perhaps from cathedral schools. <P4-S2> it is possible, however, that the development of cathedral schools into universities was quite rare, with the university of paris being an exception. <P4-S3> later they were also founded by kings (university of naples federico ii, charles university in prague, jagiellonian university in kraków) or municipal administrations (university of cologne, university of erfurt). <P4-S4> in the early medieval period, most new universities were founded from pre-existing schools, usually when these schools were deemed to have become primarily sites of higher education. <P4-S5> many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries.
