  1. THE SEPTIC ROAD SHOW Welcome Designed by: Bernards Township HEALTHDepartment Basking Ridge, NJ 07920 P. 908.204.2520 F. 908.204.3075 www.bernardshealth.org Contractual Health Agency for: Bernards Township Bernardsville Borough Chester Borough Long Hill Township Mendham Borough Mendham Township Peapack and Gladstone Borough

  2. SOME IDEAS FOR A TITLE… SOME IDEAS FOR A TITLE… The Wonderful World of Septics What Really Happens in the Septic Bed The Ways of the Effluent GOT SHOT DOWN! so here’s…

  3. EVERYTHING YOU ALWAYS WANTED TO KNOW ABOUT SEPTIC SYSTEMS, but didn’t know how to ask!

  4. Historical Perspective In earlier times, humans disposed of waste IN MORE PRIMITIVE WAYS

  5. waste disposal methods evolved As time moved on, until the present...

  6. …and the of the State of New Jersey Chapter 199 Septic Code of the State of New Jersey Local ordinances may have additional requirements.

  7. Chapter 199: Septic Code Implemented to protect our: Water Sources, and Living Environment

  8. General Regulations SOIL TESTING SEPTIC DESIGN WETLANDS RESTRICTIONS

  9. SOIL TESTING At least 2 soil logs & 1 soil test is required per lot • Type of Tests: • Perc • Basin Flood • Pit Bail • Tube Permeameter • Soils class rating samples

  10. SEPTIC DESIGN • Limiting Factors • Setbacks • Sizing the System • Meeting Specific Design Requirements • New vs. Existing Property • New Code Requirements April 2012

  11. LIMITING CONDITIONS: • Steep Slopes • Floodplains & Wetlands • High Groundwater • Mottling in Soil • Depth to Bedrock • Hydraulically Restrictive Soils • Excessively Coarse Soils

  12. DESIGNS for LIMITING CONDITIONS

  13. SETBACKS & DISTANCES

  14. SIZING THE SYSTEM SEPTIC TANK SEPTIC FIELD Number of Bedrooms

  15. SINGLE FAMILY DWELLING Septic tanks shall have:

  16. SEPTIC FIELD SIZE Depends upon Permeability Rate of the Zone Of Treatment .

  17. NEW CONSTRUCTION Designs must meet requirements of state septic code. EXISTING DWELLING • Increase in # of bedrooms: • Same as new construction • No additional bedrooms • Design best system for lot

  18. APRIL 2012 REQUIREMENTS • Tanks must be tested in the field to prove water-tightness • Marker must be attached to tank with system information • Effluent filters are required on all new tanks • All cesspools, outhouses, latrines that are part of realty transfer must be abandoned.

  19. APRIL 2012 REQUIREMENTS More • The inspection protocol is included in an appendix to Chapter 199 • NJDEP established a recognized method of septic system inspection for a real property transfer • The inspection report shall be provided to the local health department

  20. WETLANDS RESTRICTIONS • Wetlands provide: • Valuable habitat for many wildlife species. • Important storm water buffer, and groundwater recharge areas.

  21. WETLANDS RESTRICTIONS The New Jersey Department of Environmental Protection regulates wetland related activity. • In general, septic fields must be kept from delineated wetland boundaries by: • 50 feet for Intermediate Value Wetlands • 150 feet for Exceptional Value Wetlands • Before construction, approval must be obtained from the NJDEP that proper setbacks are being met.

  22. Types of Septic Systems Gravity Pump Alternative Designs

  23. GRAVITY Systems Gravity Systems use the basic laws of nature and the old adage that says ‘stuff’ will flow downhill into the septic bed.

  24. PUMP Systems In a Pump System, technology overcomes the law of gravity allowing waste water to flow uphill into the septic bed.

  25. ALTERNATIVE Systems • Peat Systems • Infiltrators • Aerobic Treatment Units • Drip Dispersal

  26. BUILDING A SEPTIC SYSTEM BACKFILL FILTER FABRIC LATERALS GRAVEL EXCAVATION SUITABLE FILL

  27. CONVENTIONAL CLEAN OUT SEWER PIPE EFFLUENT FILTER

  28. MOUNDEDSYSTEM CLEAN OUT INLET LID

  29. Zones of Treatment & Disposal

  30. Real Life Systems LINE FROM HOUSE TANKS SEPTIC BED LATERALS

  31. LINE FROM HOUSE

  32. TANKS

  33. LATERALS

  34. EXCAVATIONSITE

  35. Why be concerned about my SEPTIC SYSTEM? 2. 1. 3.

  36. How a Septic System Works Captures solids Liquid effluent distributed to disposal area Effluent treated in septic bed Cleansed wastewater recharged to groundwater

  37. Septic Tank Captures Solids Locking Manhole Cover At Grade Effluent Filter Baffle Outlet Pipe

  38. “Baffles “ Control Flow OutletBaffle keeps solids from leaving tank Effluent Filter InletBaffle slows incoming water flow. Baffle

  39. Effluent Treatment • A Biomat forms at the • gravel/suitable-fill interface., 2. Breaking down harmful organisms 3. Suitable-fill material provides additional treatment.

  40. Septic Tank Maintenance Do’s • Reduce water flows • to your system. 2. Divert surface runoff away from system. 3. Pump out septic tank regularly. 4. Locate & diagram septic tank and disposal field. 5. Effluent filter should be cleaned or changed regularly.

  41. Septic Tank Maintenance Don’t 1. Dispose of inert, toxic, or non-biodegradable substances in system. 2. Plant trees or other vegetation near your system 3. Drive vehicles or heavy equipment over the system. 4. Use biological additives or septic system cleaners that contain toxic substances.

  42. Warning! Do NOT put Toxic Chemicals here! So,No Toxic Chemicals here!

  43. Warning! Garbage grinders/disposals are incompatible with septic systems.

  44. An Old House Septic Tank Old House Seepage Pit

  45. An Old House Or Cesspool Old House At time of property transfer cesspool must be upgraded to septic system.

  46. Or a NEW House Typical Septic System in NEW House

  47. Troubleshooting

  48. HEALTH DEPARTMENT Contact • Experiencing any trouble with septic system, i.e., overflow . • Planning additions to your home. • Need to know location of present system. • Filing permit fee for construction. • Setting up inspections of new system.

  49. OVERFLOWS

  50. Follow the Steps • Soil Log & Perc test by engineer in field , witnessed by health inspector • Submit design to local Health Department or BOH • HD or BOH reviews & approves septic plans • Schedule inspections of septic installation • Complete installation of system • Design engineer submits As Built and Certificate of Compliance • Final approval issued by administrative authority
