We specialize in the design and
installation of septic systems. We
can take care of the whole process
from test hole for soil analysis,
permit, and installation to a
complete system ready to use!
There are 2 types of systems you
maybe approved for....gravity or
pressurized. The type of soil and site
characteristics determine what type
of system you may install.
A gravity system consists of a
pipe from the home to the
septic tank and from the septic
tank to the drainfield. The waste
flows by gravity to the tank
where it is broken down and
then effluent flows by gravity
from the tank to the drainfield
for final treatment.
In pressurized systems the waste
flows by gravity from the home to
the septic tank where it is broken
down to effluent. The effluent then
flows to a pump chamber where it is
pumped in specific doses to the
drainfield for final treatment. This
type of system is required to be
engineered by a Washington State
Licensed Designer or Engineer. At
J.A. Wright Construction LLC we
carry a license to design
pressurized systems.
A free brochure is available from J.A.
Wright Construction LLC which explains
how each system works and the
maintenance which should be done for
each system.
We are licensed installers and continually
receive updated information & training
about the septic industry.
