STEP Tank depth of bury not to exceed 60” from top of upper most riser lid to invert of inlet pipe to tank. (Plan Shows 96+ inch bury)
Need full set of submittals on this proposed tank.
Supply calculations supporting this proposed tank size
Step Tank needs 1 additional riser over the solids portion of tank.
Service line to be sleeved instead of encased in concrete.
Line from pumps in Tank to main on 100th Street is Service Line not Force main.
Purpose of existing manhole N.W. of New Manhole #3 is unclear. Can it be abandoned? Otherwise, integrity will need to be tested.
Supply all details pertaining to this project.
Would like to see hose bib closer to pump end of tank.
