Class 3
Back to all types of systems
A Class 3
sanitary sewage system (cesspool) may only be used for the treatment of
sanitary sewage from a Class 1 System (privy) or effluent from a Class 1
System. The use of Class 3 systems is usually discouraged because the
human body waste will quickly clog the soil particles, which will slow down
the operation of the cesspool. For this reason, Class 3 Systems usually have
a very short life and are not recommended unless all other
possibilities for the treatment of sanitary sewage have been rejected.
