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…

slide4

Historical Perspective

In earlier times,

humans disposed

of waste

IN MORE

PRIMITIVE WAYS

slide5

waste disposal

methods evolved

As time

moved on,

until the present...

slide6

…and the

of the

State

of

New Jersey

Chapter 199

Septic Code

of the

State

of

New Jersey

Local ordinances may have additional requirements.

slide7

Chapter 199: Septic Code

Implemented to protect our:

Water Sources, and

Living Environment

slide8

General Regulations

SOIL TESTING

SEPTIC DESIGN

WETLANDS RESTRICTIONS

slide9

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
slide10

SEPTIC DESIGN

  • Limiting Factors
  • Setbacks
  • Sizing the System
  • Meeting Specific Design Requirements
  • New vs. Existing Property
  • New Code Requirements April 2012
slide11

LIMITING CONDITIONS:

        • Steep Slopes
        • Floodplains & Wetlands
        • High Groundwater
        • Mottling in Soil
        • Depth to Bedrock
        • Hydraulically Restrictive Soils
        • Excessively Coarse Soils

SIZING THE SYSTEM

Number of Bedrooms

slide15

SINGLE FAMILY DWELLING

Septic tanks shall have:

slide16

SEPTIC FIELD SIZE

Depends upon Permeability Rate of the Zone Of Treatment

.

slide17

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
slide18

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.
slide19

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
slide20

WETLANDS RESTRICTIONS

  • Wetlands provide:
  • Valuable habitat for many wildlife species.
  • Important storm water buffer, and groundwater recharge areas.
slide21

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.
slide22

Types of Septic Systems

Gravity

Pump

Alternative

Designs

slide23

GRAVITY Systems

Gravity Systems

use the basic laws of nature and the

old adage that says

‘stuff’ will

flow downhill

into the septic bed.

slide24

PUMP Systems

In a Pump System,

technology overcomes

the law of gravity

allowing waste water

to flow uphill

into the septic bed.

slide25

ALTERNATIVE Systems

  • Peat Systems
  • Infiltrators
  • Aerobic Treatment Units
  • Drip Dispersal

How a Septic System Works

Captures solids

Liquid effluent distributed to disposal area

Effluent treated in septic bed

Cleansed wastewater recharged to groundwater

slide37

Septic Tank Captures Solids

Locking Manhole Cover At Grade

Effluent Filter

Baffle Outlet Pipe

slide38

“Baffles “ Control Flow

OutletBaffle keeps solids from leaving tank

Effluent Filter

InletBaffle slows incoming water flow.

Baffle

slide39

Effluent Treatment

  • A Biomat forms at the
  • gravel/suitable-fill interface.,

2. Breaking down harmful organisms

3. Suitable-fill material

provides additional treatment.

slide40

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.

slide41

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.

slide42

Warning!

Do NOT put Toxic Chemicals here!

So,No Toxic Chemicals here!

slide43

Warning!

Garbage grinders/disposals are incompatible with septic systems.

At time of property transfer cesspool must be upgraded to septic system.
