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
10/12/20142 Sanitary Survey Form Standard Info ~Current Facility ID Capacity, etc., ~Well Construction ~Treatment Process ~Storage Data ~Distribution System
10/12/20143 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.
10/12/20144 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)
10/12/ Annual Flow Data Flows rates determine if appropriate pumping capacity, storage capacity and auxiliary power requirements are being met.
10/12/20146 O & M Log Books Log books must be maintained at the treatment plant and current to the most recent visit.
10/12/20147 Wells Housekeeping Needed 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.
10/12/20148 Flow Meters Flow meters must be checked periodically for accuracy.
10/12/20149 Piping All piping must be screened (especially dump lines, overflow pipes, vents, etc.) and, labeled & color-coded (ex.: reuse = purple).
10/12/ Lime Hoppers Lime hoppers should be covered. The rooms should be kept clean. A ventilating fan is recommended.
10/12/ 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.
10/12/ Maintenance Clean, well- maintained facilities let the inspector know you share their dedication to providing safe drinking water.
10/12/ Safety Be sure sources of contamination are not stored in close proximity to wells.
10/12/ Safety Prevent unauthorized entry. Consider fences, locked doors, gates, alarms, etc. Open windows at a well house encourage unwanted visitors.
10/12/ Safety If fencing is not an option, other forms of well protection are available.
10/12/ Safety Devices SCBA* is required at all Gas Chlorination Facilities. …MUST be inspected often (according to NIOSH guidelines).
10/12/ Chlorine Rooms Chlorine rooms must be designed to meet Ten State Standards
10/12/ Chlorine Rooms Open drains in gas chlorine rooms are not acceptable (w hy not?).
10/12/ Chlorine Rooms All gas cylinders should be properly secured to a wall… And kept out of direct sunlight.
10/12/ Chlorine Rooms Hypochlorination tanks must meet with ANSI / NSF 60 standards. All openings must be protected and the tank kept out of direct sunlight.
10/12/ Chlorine Rooms Exhaust vents must not discharge near entrances. Chlorine vents must be low …preferably as far as possible from entrances. Chlorine Rooms
10/12/ Plants Labeling of all equipment and piping gets extra points from the inspector. Operating Pressures and chemical feed rates will be noted.
10/12/ Alarms Chlorine alarms must be fully operational at all times; Must be tested frequently to insure proper working condition.
10/12/ Elevated Storage Tanks Overflows should be brought down to 12” to 24” above ground level Discharge should be to a splash plate
10/12/ Elevated Storage Tanks Storage tanks with elevated overflow outlets must have both a flapper valve and a screen.
10/12/ Elevated Storage Tanks Some systems become creative in meeting certain requirements. This may not work as well as intended.
10/12/ 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.
10/12/ Concerns noted on Report: “DEFICIENCY 1: Storage tank protection Pipe inlet openings should be sealed from rainwater. RULE REFERENCE: 62 ‑ (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.”
10/12/ Site Review Surrounding areas are noted for possible sources of contamination.
10/12/ 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.
