Tips & Insights to Prepare for Sanitary Survey Inspections ( TIPSSI )

1. Tips & Insights to Prepare for Sanitary Survey Inspections(TIPSSI) • What to expect • What to have on hand • What to check For Florida’s Water Sector In coordination with FRWA and FDEP Updated 1/11

2. Sanitary Survey Form Standard Info ~Current Facility ID • Capacity, etc., ~Well Construction ~Treatment Process ~Storage Data ~Distribution System

3. Paper Work (part 1…) • Well Construction Information • Cross Connection Control Plan. • Bacteriological Sampling Plan • System Diagrams • Flow Plans, • Schematics, etc.) • MORs, Sampling Data Submittals • DEP Notices, Correspondence, etc.

4. Paper Work (part 2…) • Uni- Directional Flushing Program • Pump Specifications • Valve Maintenance / Exercising Plan • Tank Inspection Report • Signed, Sealed by a P.E. • Within Last 5 Years • Auxiliary Power Plan • Emergency Response Plan (ERP)

5. Annual Flow Data Flows rates determine if appropriate pumping capacity, storage capacity and auxiliary power requirements are being met.

6. O & M Log Books Log books must be maintained at the treatment plant and current to the most recent visit.

7. Wells All wells should be equipped with a well casing vent. In cases with no vent the disinfection port may be converted to act as a vent. Housekeeping Needed

8. Flow Meters Flow meters must be checked periodically for accuracy.

9. Piping • All piping must be screened (especially dump lines, overflow pipes, vents, etc.) and , labeled & color-coded (ex.: reuse = purple).

10. Lime Hoppers • Lime hoppers should be covered. The rooms should be kept clean. A ventilating fan is recommended.

11. Additives/Lubricants • Oil -lubed pumps must utilize food grade oils. • NSF Standard 60 Approved (or equivalent). • Hypo chlorination systems must use NSF 60 approved chlorine.

12. Maintenance Clean, well- maintained facilities let the inspector know you share their dedication to providing safe drinking water.

13. Safety Be sure sources of contamination are not stored in close proximity to wells.

14. Safety Open windows at a well house encourage unwanted visitors. Prevent unauthorized entry. Consider fences, locked doors, gates, alarms, etc.

15. Safety If fencing is not an option, other forms of well protection are available.

16. Safety Devices SCBA* is required at all Gas Chlorination Facilities. …MUST be inspected often (according to NIOSH guidelines).

17. Chlorine Rooms Chlorine rooms must be designed to meet Ten State Standards

18. Chlorine Rooms • Open drains in gas chlorine rooms are not acceptable (why not?).

19. Chlorine Rooms • All gas cylinders should be properly secured to a wall… • And kept out of direct sunlight.

20. Chlorine Rooms • Hypochlorination tanks must meet with ANSI / NSF 60 standards. • All openings must be protected and the tank kept out of direct sunlight.

21. Chlorine Rooms Chlorine Rooms • Exhaust vents must not discharge near entrances. • Chlorine vents must be low …preferably as far as possible from entrances.

22. Plants • Labeling of all equipment and piping gets extra points from the inspector. • Operating Pressures and chemical feed rates will be noted.

23. Alarms • Chlorine alarms must be fully operational at all times; • Must be tested frequently to insure proper working condition.

24. Elevated Storage Tanks • Overflows should be brought down to 12” to 24” above ground level • Discharge should be to a splash plate

25. Elevated Storage Tanks • Storage tanks with elevated overflow outlets must have botha flapper valve and a screen.

26. Elevated Storage Tanks • Some systems become creative in meeting certain requirements. This may not work as well as intended.

27. Storage Tanks • All vents must be properly screened to help prevent contamination. • Tanks should be kept in good condition w/a proper pressure release valve.

28. Concerns noted on Report: • “DEFICIENCY 1: Storage tank protection·Pipe inlet openings should be sealed from rainwater. • RULE REFERENCE: 62‑555.330(3) • RECOMMENDED ACTION: Refer to Ten State Standards: finished water structures shall have suitable watertight roofs which exclude birds, animals, insects, and excessive dust.Please correct by August 31, 2011.”

29. Site Review Surrounding areas are noted for possible sources of contamination.

30. Testing Chlorine and pH readings will be conducted during the survey. Proper testing equipment must be on-hand and properly maintained.

31. Storage Tanks Some pictures need no explanation. oooxx++xxxxxo
