Problem
The project needed reliable sewage transfer for a Mysore facility where the wet well layout was constrained, clogging history on the previous pump was frequent, and access for maintenance required a crane or lifting arrangement.
Engineering review
FlowCore reviews peak inflow, solids profile, wet-well depth and plan dimensions, pump extraction arrangement, float switch placement, cable routing and IP rating, duty-standby changeover, discharge static head, and whether sump cleaning access is practical without dewatering the wet well.
- Solids passage diameter — matched to solids loading at the site
- Impeller type — vortex, single-channel, or multi-channel depending on solids
- Float switch placement and set points for start, stop, and high-level alarm
- Standby pump changeover — auto or manual, and how it is tested
- Discharge head and check valve arrangement
Solution approach
A submersible sewage pump package with guide rail extraction, correct impeller selection for the solids profile, auto-changeover between duty and standby, and an accessible clean-out point for periodic wet-well maintenance.
What this project confirms
STP pumps should be selected for the wastewater reality at the site — solids type, wet-well access, service frequency, and standby logic — not for clean-water rated flow alone.
