Drainage Field and Types – Complete Septic Systems in Hayward, WI
Let us Introduce
Ourselves!
Hello, my name is Mark Thompson I am a Wisconsin state
certified & licensed master plumber restricted service & soil
tester license # (877598).
Even though my business is new, I am not new to the area. I
have been installing septics and soil testing in the Hayward
area for 25 years. I was previously employed through
Thompson’s Sand & Gravel.
Soils & Septics, who needs them?
Whether you are in the market for a new piece of property, and
need a soil test, or your existing system is failing, or just not big
enough, that’s where I come in.
Soils:
Before a septic system can be installed a state certified soil
evaluation must be performed by a licensed soil tester. The
property needs to be evaluated for proper setbacks and
acceptable soil conditions. A sanitary permit cannot be pulled
without a soil test.
Septic’s:
Once a soil evaluation has been performed, you can then apply
(through a master plumber) for your sanitary permit. We then
will file the necessary paperwork and fees with the County
and/or State for approval. Once it is approved the installation
process can begin
Septic Permits and Paperwork—We Handle It All
Once your soil test is approved, we apply for your sanitary permit through your county or the State of Wisconsin. As a licensed Master Plumber Restricted Service (MPRS), Mark Thompson files all necessary documentation and pays required fees on your behalf.
“We take care of the paperwork so you can focus on your property.”
Different types of septic systems
There are many different types of septic systems that can be installed.
depending on the type of soil, amount of land we have to work with, and necessary setbacks.

Conventional
A conventional gravity flow
system is acceptable when there
is ample amount of property, and
a nice sandy soil is present.
Also, if the waste from the house
can freely flow from the house to
the tank, then from the tank to the
drain field.

Pump-Up System
A Conventional pump-up system
is pretty much the same as a
conventional except the effluent
is required to be pumped from the
tank up hill to the drain field.

Mound System
A mound system is required
when the soils are unacceptable
to handle a typical conventional
system. It is usually a pump-up
system to a drain field that sits
above ground. The materials used
for the mound must meet state
specifications.

At-Grade System
An at-grade system is needed
when the soils are acceptable to
certain point then turn bad. It
typically doesn’t sit as high as a
mound but is partially above
ground.

Holding Tank
A holding Tank is required when
the soils are not acceptable for a
drain field, and/or the property
has insufficient space to handle a
drain field. Holding tanks are
regulated by the county and are
subject to the laws set in place by
each county, which may differ
from county to county.
