Description:
Pump intake basins (or wet wells or pump sumps) designed in accordance with accepted criteria often pose many operation and maintenance problems. The report summarizes field surveys of three trench-type pump intake basins representative of 29 such basins that have been in satisfactory service for nearly three decades, large-scale (1:4) model studies made at the ENSR Consulting and Engineering hydraulic laboratory in Redman, Washington and at Montana State University in Bozeman, Montana, and a full scale basin study made at Fairbanks Morse Pump Corporation plant in Kansas City, Kansas. Field studies of three small, round pump inlet basins are also included. A considerable part of the report is devoted to recommended procedures and rules for intake basin design. The effectiveness of cones and vanes in reducing swirling is also reported together with means for reducing or eliminating vortexing.
