STEP Tank depth of bury not to exceed 60” from top of upper most riser lid to invert of inlet pipe to tank.
Is this a duplex pump system?
Manholes need to be constructed in such a way as to allow NO infiltration. Prefer to have no man holes or piping through the manholes with clean-outs available within the manholes.
No clean out needed at end of service line.
Hose bib req. w/in 50’ of tank
Supply calculations supporting this proposed tank size.
Need full set of submittals on this proposed tank.
