The St. Anthony Falls Hydraulic Laboratory (SAFHL) performed field
flow measurement tests for six large Venturi meters (MI00A, MI00B,
MI0IA, MI0IB, MI02A, MI02B) owned and operated by the Metropolitan
Waste Control Commission (MWCC), and installed in the 1930's. The
MWCC oversees the collection and treatment of sanitary wastewater
discharges in the Twin Cities Metropolitan area of Minnesota. The tests
were completed as a subcontract to James M. Montgomery Consulting
Engineers, Inc. (JMM), of Wayzata, Minnesota, with whom the MWCC had
contracted to conduct an overall evaluation of the Venturi meters.
Four of the six Venturi meters (Fig. 1) were located on the west bank
of the Mississippi River, just upstream from the Lake Street bridge; two of
these meters had throat diameters of 42 inches, with the other two having
throat diameters of 25 inches. The two remaining meters (Fig. 2), each
with a throat diameter of 25 inches, were located at the Minneapolis-St.
Paul border, along the east bank of the Mississippi River.
