STP & ETP Maintenance Mistakes

The most common operational errors that cause treatment plant failure, compliance issues and shutdowns.

Why Most STP & ETP Plants Fail

More than 70% of STP and ETP failures are caused not by design flaws, but by poor operation and maintenance. Ignoring routine checks, biological health and monitoring leads to odor, poor treated water quality and regulatory action.

Critical Maintenance Mistakes

Ignoring pH & Biological Health

Unbalanced pH kills bacteria, reducing treatment efficiency and increasing COD/BOD levels.

Improper Sludge Handling

Excess sludge accumulation leads to overflow, odor and poor settling performance.

No Preventive Equipment Checks

Blowers, pumps and diffusers fail due to lack of routine inspection and servicing.

How Poor Maintenance Affects Compliance

  • ✔ Treated water fails CPCB discharge norms
  • ✔ Online monitoring shows repeated violations
  • ✔ SPCB issues show-cause or closure notices
  • ✔ Increased chemical and power consumption
