Question: Taicang city and Beibei District are next to what type of water system?
Context: The Silver City Water Works Building is a historic building located on Little Walnut Rd. in Silver City, New Mexico.  The building was constructed in 1887 to provide Silver City with a municipal water system.  While the city had established an electrical system and telegraph connections, it lacked reliable drinking water and a fire prevention system, as an earlier attempt to build a water system was never completed.  George H. Utter obtained a contract to supply water to Silver City in 1886, and he commissioned Michigan stonemason John Hill to build the water works.  The sandstone water works is the only sandstone building from the 1800s in Silver City, as brick was a much more common building material.  While the water system opened and initially operated successfully, by 1890 Utter was accused of supplying undrinkable water and failing to meet the city's expectations for service.  East Coast investors Henry and Thomas Foster took over the water works in the ensuing years after an extended legal battle with Utter. The Standing Rock Rural Water System (RWS) is a $30 million water system funded by the American Recovery and Reinvestment Act in 2009 for about 10,000 residents of the Standing Rock Sioux reservation in North Dakota.  The RWS includes the Standing Rock Water Treatment and the "Indian Memorial Intake Pump Station, a raw water pipeline, two transmission pipelines and Kline Butte Storage Reservoir."  The main regulation reservoir of the Standing Rock Rural Water System is the $3.6 million Kline Butte Storage Reservoir, located southwest of Kenel, South Dakota, which consists of a 5 million gallon ground storage reservoir.  Currently, (in December 2016) the intake valve for the water system is "located in a shallow part of the Missouri River near Fort Yates, North Dakota, roughly 20 miles from the planned river crossing of the controversial Dakota Access Pipeline also known as the Bakken pipeline.  The Bakken oil pipeline Dakota line is to be "buried 92 feet below the riverbed in hard clay."  A new valve came online in 2016 in Mobridge, South Dakota which is seventy miles south of the proposed Bakken Pipeline Missouri River crossing.  This Mobridge intake valve is intended to service the entire Standing Rock Sioux reservation. Lei Zhengfu (; born July 1958) is a Chinese former politician who served as Communist Party Secretary of Beibei District, Chongqing municipality.

According to the authors of the book entitled, "Integrated Urban Water Management: Humid Tropics", IUWM is described as the practice of managing freshwater, wastewater, and storm water as components of a basin-wide management plan.  It builds on existing water supply and sanitation considerations within an urban settlement by incorporating urban water management within the scope of the entire river basin.  One of the early champions of IUWM, SWITCH is a research program funded by the European Union and seeks to shift urban water management away from ad hoc solutions to a more integrated approach.  IUWM within an urban water system can also be conducted by performance assessment of any new intervention strategies by developing a holistic approach which encompasses various system elements and criteria including sustainability type ones in which integration of water system components including water supply, waste water and storm water subsystems would be advantageous.  Simulation of metabolism type flows in urban water system can also be useful for analysing processes in urban water cycle of IUWM.
