About
I have been in the industry since I was 16 years old. I have serviced more than 20,000 systems and installed hundreds. I am licensed through the Minnesota Pollution Control Agency (MPCA).
Our aim is to help homeowners who have a private septic system and those who are selling/buying a home and need an upgraded system.

Team

This is Mark
Mark has been in the Princeton area all of his life and attended Cambridge High School. He started his septic and excavating career when he was 12 years old. It was a summer job that his mom had to drive him to and his uncle would bring him home from. It worked out even better when he got his driver's license. The summer he was 16 the Minnesota Department of Transportation was stopping trucks for random safety checks. This didn't go well since a normal driver's license is only good for 26,000 pounds. The truck was much more than that, however the inspector let him drive it to his grandpa's house to park it and didn't even issue a ticket. When he turned 18 he got his class A license. For the next several years - still working for his uncle - he installed new systems and conducted service work, including pumping septic systems.
By 2002 he decided to start working in the cities for a large excavating company, and then moved on to a commercial masonry company running equipment. He had bought his first pumping truck and was starting to fix it up. By June of 2003 Mark's Sewer Service was in business. By late 2003 he found it was impossible to have two jobs and took a voluntary layoff from the masonry contractor. He's been full time (and then some!) with Mark's Sewer Service since then.
In 1999 Mark and his wife Tammy had their first child Katelyn, and in 2001 their second child, Alexander. The first couple years were stressful with little kids and a new business. He and his wife Tammy made it work one day at a time.
It took several years before he felt confident enough to hire full time help. He had seen that go horribly wrong for other new businesses. Through careful expansion over the years he has added several quality people to the team.
