Chapter 3: General Regulations

By R. Dodge Woodson
From Water Wells and Septic Systems Handbook

The general regulations of the septic code are not extensive. They are, however, important to know and observe. Let s take a look at them now.

Specific Limitations

Domestic waste, which includes all wastes and sewage derived from ordinary living uses, must terminate in an approved septic or treatment tank if a public sewer connection is not available. It is possible for a code officer to create a variance to this requirement. Privies are not allowed. Except where specifically approved by a code officer, cesspools are prohibited.

The disposal of industrial wastes must be approved by a code officer. Certain objects must be prevented from entering a private sewage system. Some of the prohibited materials include:

  • Ashes

  • Cinders

  • Rags

  • Flammable substances

  • Poisonous substances

  • Explosive liquids and gases

  • Oil

  • Grease

  • Insoluble materials

Clear water, such as surface water, rain or other clear water, shall not be allowed to enter a private sewage-disposal system. Water from a water softener or iron filter backwash must discharge into a septic system, unless it can be disposed of on the ground surface without creating a nuisance.

Flood Plain

A flood plain can create a serious problem for the installation of a septic system. Soil absorption systems must not be installed in a floodway. This type of system is also prohibited in a flood fringe, unless specific approval is given by a code official. No new sewage-disposal system may be installed in a floodway.
