First Truck | About Us | M&O Sanitation

M&O Plumbing Co, Inc. (dba M&O Sanitation, Miller Haulers) was founded by John and Julia Miller in 1974.  They successfully ran the business for almost two decades.

In 1992, the Millers put the business up for sale.  Heather Miller, their daughter, grew up learning the ins and outs of this business from the best teachers around- so when the business was put up for sale, she knew she wanted it to stay in the family. They worked out a deal and Heather became the proud owner of M&O Sanitation Inc in 1994.

Your Number 2 is our Number 1!”

Heather grew up hearing all the jokes about septic- “You Dump It….We Pump it!”, and the list goes on and on.  M&O would design their own logo and “When S¢ents Count” phrase later on.

In 1993 M&O Sanitation Inc was primarily pumping septic tanks and doing some installations; it was at this time Heather recognized the need to diversify. She and her husband, Albert, began attending Waste Hauler Expos to further educate themselves and invest in additional sewer related equipment. This is where they decided to expand into portable toilets and later, sewer equipment.

M&O Sanitation now pumps septic, installs septic tanks and systems, cameras sewer lines, flushes sewer lines, snakes and high velocity water jets lines, portable restrooms for parties and events, porta potties for construction sites.
