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, 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 (28 m) 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.
