  1. Iowa Department of Natural ResourcesPrivate Sewage Disposal Program Iowa Environmental Health Association Fall Conference 2012

  2. In Remembrance

  3. Communication

  4. Your Contribution to Water Quality • Approx. 300,000 septic systems in Iowa • 52.5 million gallons of wastewater generated every day • Approx. 7500 systems permitted each year (1.3mgpd)

  5. Thank you!! • Approximately 15,000 inspections • Repairs without ToT inspections not counted • About 1/3 require repair or replacement • 302 inspectors renewed • 5000 new systems = 875,000gpd of previously untreated wastewater now being treated (or 300 million gallons annually)

  6. Rule changes – Ch 68 • On farm food processing law • Wineries, cheese making etc. • Produces less than 1500gpd • Meets definition of “on-farm food processing facility” • Provides options for disposal • New option – land application • Old options; Class V well, POTW, holding tank

  7. Rules Changes – Ch 69 • Standardize definition of PSDS • Renew GP4 • New language for state owned lakes, OIW’s, anti-deg • Site evaluation done by administrative authority • Public well separation distances

  8. Ch69 changes continued • Added 150gpd/bedroom language • Standardize certified technician language • Removed “person demonstrating knowledge” • Effluent screens can replace baffle • Risers must also be 18” in diameter

  9. Ch 69 changes continued Added IAPMO language for plastic tanks Remove maximum width for mounds, at-grades Added “or an intermittent sand filter” language to emphasize this option before other media filters

  10. Ch 69 changes continued • Maintenance contracts provided to county BEFORE installation • Homeowner knows what will be required • Removed requirement to record maintenance contract in abstract

  11. Ch 69 changes - ToT 10 working days to submit report Added existing exemptions to rule Added existing real estate contract language Removed “provide copy to Recorder”

  12. Ch 69 changes - ToT • Removed E. coli testing for ToT only • Removed recording in abstract • Added binding agreement for future install • Changed NPDES requirements for inspector • Report location of discharge not whether permitted

  13. Inspection Example • Ask about the septic system when they call for an inspection. • How old is the system? • Do you know where the septic tank is? • Where does it go after that? • Where is the secondary treatment? • Is the house occupied? • Do you have a mean dog?

  14. Inspection Example • Contact the county environmental health/sanitarian office • Is there a permit? • Get a copy • Does the homeowner have a copy of the permit or a drawing ? • Other records? • Pumping, maintenance, service contracts

  15. The Inspection Site • Authorized entry? • From homeowner or agent • Lender or agent? • Authorized entry form • Recommended • Is the water on? • Hydraulic loading test • Haul water?

  16. The Inspection Site • Indoor plumbing • Does everything go to the septic tank? • Older homes may have sinks, washing machines, basement fixtures etc. that do not go to the septic system

  17. Basement Plumbing

  18. Indoor Plumbing

  19. Finding the Tank • What direction does the sewer leave the house? • Location of main vent on roof frequently above the main sewer pipe • Depression or dry spot in yard • Your best friend – the tile probe!

  20. Location of Septic Tanks and Soil Absorption Field Lines Could ask neighbor, previous owners, current owners, or their representative Ask original installer Ask regulatory agency for files/permits Depressions in the soil Probes Trace sewer line from basement Use Locator Technology Must detect it to report it!!!!!

  21. Uncovering the tank • Both lids to the tank must be uncovered • Inspecting the tank using small diameter risers is not sufficient • Tank lids must be accessible

  22. Uncovering the tank

  23. Uncovering the tank

  24. Inspecting tanks

  25. Inspecting tanks

  26. Pump/siphon tanks

  27. Locate Find the system Gravity- Downhill Pump- Anywhere Tools Map Probe Locator Witching

  28. Use of Probe to Locate Components for Digging

  29. Uncovering the D-box • The distribution box must be uncovered • Many need replacement (concrete) or adjustment • Provides evidence of secondary treatment • Header pipes • Exposed trenches

  30. Uncovering the D-box

  31. Inspecting D-boxes

  32. D-boxes

  33. Hydraulic Loading • Ideally we run water from the house to the septic tank • Watch level in tank/box • Should stay constant • If tank has been pumped, add water to tank outlet or d-box • Use your own hose! • Caution! High flow rate • Garden hose calculator

  34. Hydraulic Loading

  35. Dye Testing

  36. Dye Testing

  37. Probing the field or sand filter • Tile probe • Be careful! • Underground electric • Sludge on probe indicates poor condition • Overloaded field may flow out of probe hole

  38. Probing fields

  39. Location of Septic Tanks and Soil Absorption Field Lines Must have some evidence of absorption field Noticeable odors from the field? Excessive areas of vegetative growth due to water and nutrients Obvious signs of past discharges of sewage (black areas, lack of vegetation, etc)? Was sewage or dye evident after dosing cycle or hydraulic loading?

  40. Discharging Systems • Sand filters • Locate vent pipes and discharge pipe • Note if there are no vents • Take a effluent sample, BOD, TSS, E. coli • If no discharge and no evidence that it has discharged report that • Packaged systems • Ensure parts are there/working as outlined earlier • Take sample

  41. Reporting • Fill out appropriate sections of the inspection form • Write a narrative report fully describing what was found • MORE information is better! It will protect you. • Take pictures if something is questionable • Provide report to county, DNR and person who ordered the inspection

  42. Report Examples Report everything that you saw! Go with too much information as opposed to too little. It will protect you! The narrative report is required and is your opportunity to expand on what you put on the inspection sheet. Provide inspection sheet (filled out), a narrative and the drawing.
