Pressure Drainfield
Description:
A pressure drainfield consists of a network of small pipes under ground. Effluent
is pumped to the pipes under pressure and a manifold is used to split the flow
evenly between multiple lines. The effluent is sprayed out of the pipes through a
series of small holes, then it moves down to the bottom of the trench or bed and
into the original soil.
Function:
A pressure drainfield disposes of effluent by allowing it to absorb into th
underlying soil. The soil provides an oxygen-rich surface area for treatment.
Microbes consume most pollution out of the water as it flows through into the
environment.
Maintenance:
• Pressure drainfields must be checked a minimum of every 5 years
Homeowner's should inspect the system annually.
• Check the observation ports for ponding wat
• Have laterals flushed as needed.
• Clear drainfield of large vegetation & ensure ports ar
• Check drainfield area for soggy spots or breakouts.
• See Sections 1 & 2 for more information on protecting your drainfield.
