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.
