  • Septic tank with integral direct distribution system
    Patent number: 4789487
    Abstract: The present invention entails a septic tank having an internal and integral distribution system formed therein for directly directing waste material from the tank without requiring the waste material to pass into and through a distribution box. The septic tank includes a distribution wall with a series of outlet ports that connect to a series of drain lines that extend throughout a drain field. A distribution baffle is secured closely adjacent the distribution wall and effectively controls the flow of waste material from the containing section of the septic tank to the distribution area that is defined between the distribution wall and distribution baffle.
