Sewers / Combined Sewer Overflows / Storm Tanks
Combined Sewer Overflows (CSOs) are used to spill storm water during heavy rainfall. Storm Tanks act as a source of capacitance, providing storage of storm water until the storm load subsides.
It is desirable that both systems when necessary allow the flow to spill with minimal loss of solids.
MMI Engineering uses Computational Fluid Dynamics (CFD) to assess the effectiveness of a CSO or Storm tank at retaining solids. Additionally, MMI Engineering also undertakes preliminary assessments of vac flush systems used for flushing solids from Storm Tanks and hydroejectors used for homogenising the solids during drain down.
