Water treatment process The Sam H. Hobbs Water Treatment Plant provides billions of gallons of water to residents and businesses and is expanding to meet growing needs. The Water Treatment Plant controls the first step in processing the safe water that comes out of your tap. The steps include:
Water treatment processThe City's Sam H. Hobbs Water Treatment Plant treats groundwater from six deep wells and then pumps it into the distribution system for use by residents and businesses. Four wells were put in service in the mid-1970s and two more were added in 2002 as part of the water treatment plant expansion. Bloomington supplements its water supply by purchasing treated surface water from the City of Minneapolis because our plant does not have the capacity to treat and supply all the City's water needs, especially on hot summer days when demand rises to its highest. This water is delivered via a pipe system from the Minneapolis Water Plant to Bloomington reservoirs where it is then pumped into the distribution system. All of Bloomington's water connections receive water that is a blend of water from our plant and water from Minneapolis. The water plant monitors and controls the inflow of water to the reservoirs and pumping into the distribution system by utilizing a state-of-the-art Supervisory Control and Data Acquisition (SCADA) system. This system allows the plant to monitor and control the pumps and valves that control the water pipes supplying the reservoir as well. Tests are conducted on water during the treatment process, as it enters the distribution system, and on samples routinely collected from sampling points throughout the city. Over 85,000 tests are performed on our water annually. Bloomington's water consistently meets or exceeds all of the criteria established by federal and state regulations and guidelines.
