to the top of the hill to set tank.  
STEEP!
Made it to the top.  Now setting
tank in the ground.  Note extremely
rocky conditions (perfect for an
alternative system).  Leach field is
pressurized drip distribution.

gravity flow to chambers (Mt.
Lemmon)
One of our three chamber tanks at
our precaster's yard in Tucson.
500 gallon per day pressurized drip
distribution with field designed to
water entire backyard area (Oracle,
AZ.)
Large system for a public building
capable of handling thousands of
gallons per day if necessary.  
Reuse of effluent for landscaping
makes this one of the few "green"
public buildings (Show Low, AZ.)
Two control panels on a very large
residential system with pressurized
drip distribution.  Large panel at
left controls most functions on this
particular system including for
dosing.  Small panel on right is a
"gravity" system panel to
accommodate a second tank
aerator for this 8000+ square foot
home (Tucson, AZ.)
We carry Arizona
state approved
nitrogen reduction
alternative septic
systems.

inspection on a 750 gallon per day
"gravity" system at the base of Mt.
Lemmon.
Field and tank orientation of the
same system as above.
Pressurized drip distribution of
effluent.  This area was cleared and
gravel was spread under and
"shaded" over tubing.  The entire
field was then covered with native
soil.  Area is then re-vegetated with
native plants (Vail, AZ.)
500 gallon per day system with
pressure distribution.  This one is
installed completely in native soil
(Vail, AZ.)
Excavator standing next to his
handiwork.  Tubing is pressurized
and emitting water during testing.
Large multi zone pressure distribution field trenched
into native soil and backfilled with screened native
soil.  Additional spacing between some tubing is to
accommodate 12-14 mesquite and palo verde trees
(Tucson, AZ.)
Concrete riser houses the filter,
chlorination and dechlorination
tubes, and chemical monitoring
device.  Not all system designs call
for the chemicals (disinfection) and
monitoring device but they are
easily installed when needed.  The
filter is easily lifted out for cleaning
when necessary and remember
these systems don't smell so
maintenance is a breeze!

received from
Sonomex.  The
Norweco alternative
system has been
great!

Seepage pit installation in Maricopa
County (Cave Creek).  A great
alternative when soil conditions
permit.  Very effective and smallest
field "footprint" by far!
Same Cave Creek job as above.  Only
a few companies use this specialized
equipment to install alternative septic
systems.
