Raw Water Intake and Screen Inspection

Inspection template for raw water intake structures, screens, and pumps at a treatment plant to identify debris accumulation, physical damage, flow obstruction, and conditions that could affect raw water delivery ahead of treatment.

Inspection Details and Site Identification

• Inspection date and time recorded
• Intake location, structure ID, or station identified
• Inspector name and role documented
• Weather, water level, or flow conditions noted if relevant
• Inspection performed under required access controls and PPE
  Verify site-specific PPE and access controls were followed before entering the intake area.

Raw Water Intake Structure Condition

• Intake structure free of visible damage, cracking, corrosion, or displacement
  Inspect concrete, steel, grating, housings, and support members for damage that could affect structural integrity or flow.
• Access platforms, ladders, and walkways secure and unobstructed
• Signs of erosion, undermining, leakage, or unusual seepage observed
• Trash racks, grates, and protective barriers intact and properly seated
• Debris accumulation at intake structure
  Estimate the percentage of visible intake opening or screen area affected by debris.

Screen Condition and Flow Obstruction

• Screens clear of leaves, sticks, algae, trash, or other debris
  Verify the screen face and surrounding area are not obstructed by material that could reduce intake capacity.
• Screen damage, tears, bent bars, or missing sections observed
• Screen differential pressure or headloss within acceptable operating range
  Record the measured differential pressure or headloss across the screen if instrumented.
• Screen cleaning mechanism operating normally
  Verify traveling screens, brushes, spray systems, or rakes operate without binding, unusual noise, or missed cycles.
• Bypass, overflow, or bypass channel free of blockage

Pump and Mechanical Condition

• Raw water pump operating without abnormal vibration or noise
  Listen and observe for cavitation, bearing noise, misalignment, or other abnormal conditions.
• Pump suction and discharge lines free of visible leaks
• Pump seals, couplings, and guards in good condition
• Pump suction pressure or flow rate within expected operating range
  Record the current operating value if available from local instrumentation or control system.

Operational Status, Notifications, and Sign-Off

• Any abnormal conditions, alarms, or restrictions reported to operations or maintenance
  Document whether issues were escalated according to site procedure.
• Corrective actions initiated for any deficiency or non-conformance
  List work order numbers, temporary controls, or follow-up actions for any observed issue.
• Inspector signature
• Supervisor or reviewer acknowledgment
