Aggregate Rock System
Aggregate rock drainage
has been in use since Roman times. This means there is hundreds
of years of success and knowledge of what works and what
First a Bed or Trench (drainfield) is dug in your yard.
This must conform to the requirements of the Health Dept.
permit. They are the ones that tell us what size it must
be. However our over 40 years of experience gives us a pretty
good handle on what size it should be.
In some cases a digout must be done and additional septic
sand must be put into the hole. Generally the reason for
this is because the Health Dept. inspector has found soils
that are not compatible to drainfield use. All of this must
be removed from the site and cannot be used for cover on

After the hole is dug, we use lasers to make sure
it is the correct depth and level. Our crew then installs
the special patented pipe we use. We use patented
clamps to suspend the pipe at the correct height off
of the ground. Again lasers are used to insure level.
The crew then puts the rock (aggregate) into, and
around the pipe. By state requirements it must be
6” below the pipe 4” besides the pipe
and 2” above.
We use a conveyor type of truck to distribute the
rock evenly under, around, and on top of the pipe.
We then cover the entire field with a special paper to keep sand and
dirt from getting into the rock. We then call the
Health Dept. again for a final inspection. Within
a few days they will come out and check our workmanship.
Making sure we stayed the proper distance away from
all wells, and that we built the system according
to the permit requirements. During this process they
check the width, length, depth and size of the system.
If this passes and it generally does, they then issue
a final order to cover.
Within a few days after getting this approval we
will arrive and cover the drainfield and smooth it
out. Making it ready for your sod and or landscaping
One of our systems we opened up for inspection
after 10 years in use.
Please note the fabric paper is still above the
rock and everything working as designed. The drain

One of the competitors systems is designed for
the water to run directly into the pipe or chamber
and drop directly into the ground on one end. They
do not use rock for the water to dissipate through;
it goes directly into the soil. This saturates the
soil a whole lot faster in one place and can create
premature failure of your system. Water does not pass
through soil as fast as it does in a rock system.
It actually forms a large pond or lake of contaminated
water below your grass.
They advertise that the chamber systems stores up
to 40% more water than the aggregate (rock) systems.
Why would you want a large pond as mentioned above
of septic water in your front yard?
The ideal way is to filter the water through the
rock (just like the Romans did) before it passes down
into the soil. Not to store it in a cavernous chamber.
Stacked Pipe System Another system
on the market is an all pipe system. Here water passes
from one pipe into another pipe below it, before going
directly into the soil below. They are replacing the
extra stacked pipe for rock. These systems do not
properly dispurse water.

This system was only 3 years old.
A third competitive system uses pipe encased in a netting
holding Styrofoam peanuts. Here the water flows out of the
pipe through the foam peanuts directly into the soil. Imagine
if you will what happens when the foam is saturated with
water? It collapses. Again no rock is used for filtering.
Why are these alternative systems so popular? The only
reason is because they are easier to install. No heavy equipment
is necessary other than digging the hole. The installer
digs the hole, walks up and throws the pipe into the ground,
covers it and walks away.
