The designs of pump sumps for seven different projects, as developed through hydraulic model testing, are compared with published design standards. Modifications to the sump designs, in addition to the basic sump dimensions recommended by the published standards, are required to achieve satisfactory hydraulic performance. It is theorized that performance criteria applied in developing the standards are not as stringent as those required for present day large capacity pumps. Typical sump modifications and dimensions presented may provide a basis for developing conceptual designs for sumps for large capacity pumps. Final designs should be proven through hydraulic model testing.
