  1. Sanitary Survey Preparation National RCAP Conference New Orleans, LA

  2. Objectives • Understand the basics of SS Inspection for common areas of a PWS • Be able to complete basic sanitary evaluations of PWS’s • Know where to obtain more information on SS process

  3. Lets Play!! • Stump the Chump! • In your group write THREE QUESTIONS!

  4. What Is a Sanitary Survey? • (CFR 141.2) an on-site review of the water source, facilities, equipment, operation, maintenance, and monitoring compliance of a public water system for the purpose of evaluating the adequacy of such, source, facilities, equipment, operation and maintenance for producing and distributing safe drinking water.

  5. What is a Sanitary Survey? (cont.) • An inspection of records and facilities of a PWS to ensure public health. • An opportunity to establish a “field presence” for education and assistance • Assess system capacity/Personnel

  6. Eight Key Areas • Water source • Operator compliance with state requirements • Distribution system • Pumps, pump facilities and controls • Treatment and finished water storage • Cross-connection control • Operational safety • Water system management and operations

  7. Why is a S.S. Performed? • (40 CFR 142.10) each state, pursuant to appropriate State legal authority, must establish…a systematic program for conducting sanitary surveys…the frequency with which a State conducts…be based on but not limited to a plan completed by the state, or a negotiated number per year

  8. Why is a S.S. Performed? (cont.) • Does system produce Safe Drinking Water • “multiple barrier” protection • Improve system Compliance • Operator education • Update system information • Examine limiting factors • Security/Risk Assessment

  9. When is a S.S. performed? • State regulations • 3 Year routine cycle/SW • 5 Year routine • Complaint/Follow up • Violation/Compliance Follow up

  10. System Classification • Community PWS serves 15 connections year round or; 25 year round residents • NTNC PWS serves 25 “same persons” over 6 months per year • Transient PWS Does not regularly serve 25 of the same persons

  11. System Classification (cont.) • Population Served • Source Water • Chemical Injection • Filtration Technique • Check State Regulations

  12. Who can perform the Sanitary Survey? • State agencies • Private Vendors • RCAP agencies • Local Health Officials • Check State Requirements

  13. Preparing For The Survey • Review Reporting Forms • Review Records System schematic/map Previous reports Source information Compliance Information Operator Records

  14. Inspection Tools • Pressure Gauge/Adapters • Chlorine test kit • GPS Equipment • Digital Camera • Binoculars • Flashlight • Tape measure • Thermometer • pH meter • Knife • Mirror • Various test kits

  15. Source Inspection • Wells/Surface intakes etc. • Raw water piping • Emergency power • Security/Safety concerns • Control system • Chemical feed systems • Adequacy of Source

  16. Source Inspection (records) • Historical data • Protection Plan • Quantity records • Quality records • Contingency plans • Verify VA completion

  17. Well Construction • Hard to see! • Check records • Geologic • When was it installed • Has it been inspected • Draw down tests • Chemical/mineral

  18. Your New Wells!!

  19. Treatment Inspection • What and Why • Time consuming? • Operating to Standard? • Specific regulations for each treatment?

  20. Treatment Records • MCL/Compliance data • CCC program • Operator training • O&M records • System Capacities • Chemical Injection data • Historical Treatment Technique records

  21. Treatment InspectionGeneral Areas • Schematic • Adequacy of treatment • Test equipment • Redundancy • Chemicals/Feed sys. • Emergency power • Sanitary Conditions

  22. Distribution System Inspection

  23. Distribution System • Map and expansion plan • Materials • Disinfectant residuals • CCC Program • Age/Condition

  24. Distribution System • Control System • Procedures • Repair and installation • Flushing • Water audit findings • Valve program • CCC • SDWA regulation compliance

  25. Types of Tanks • Clearwells and other chlorine contact facilities • Ground storage tanks • Elevated storage tanks • Hydropneumatic tanks

  26. Elevated Steel Storage Tanks

  27. Bolted Steel Tanks (Standpipes)

  28. Concrete Storage Tank

  29. Redwood Storage Tanks

  30. Plastic Storage Tanks

  31. Typical Tank Components

  32. Your Tank

  33. Storage • Condition of Storage • Coating Data • O&M records/program • Overflow Piping • Control System • Security Measures • CT Verification

  34. Need for Planning ????

  35. Pumping Facilities • Overall Condition • Type/Capacity • Emergency power • Flood potential • Security • Control System

  36. Pumping Facilities (cont.) • Records • O&M Program • Quantity data • Verify VA • NSF on all Chemicals • Emergency Plan Confined Space Entry

  37. Reporting/Data Verification • Sampling plans • Monitoring schedule • Verify reporting vs. Agency information • Water Quality/MCL Data • On-site Operational Logs • Accuracy of Monitoring/Sampling • Record Keeping Timetable • CCC Inspection logs

  38. Management/Operation • Operator information • Training/Support plan • Emergency plan • Conservation plan • Safety program • Public notification plan • Revenue/Budget

  39. Exit Interview • Review with management/operator • Identified Issues • Recommendations • Primacy agency actions • Timetable for corrective action • Agencies that can assist with corrective action

  40. Violations vs. Significant Deficiency • Violations or Significant Deficiencies • Only issues directly covered by regulation • Recommendations • All other issues revealed by inspection • Communication with Primacy Agency and knowledge of Specific State Regulation is a Must in this area

  41. Review • Review State Regulations • TA Site Visit • Review Records • Inspect • Compile O&M Manual • Reporting • Follow Up/Assistance
