Multiflo is a performance septic tank. It treats sewage much the same as a municipal treatment plant does, and offers environmentally concerned individuals a better way to dispose of on site waste water. Multiflo units are used to rejuvenate failing septic systems. Whether installing new or upgrading your system, consider Multiflo; it may be the only septic system you'll ever need for your home. A little Multiflo history: Palmen Septic Services maintains one of the area's oldest multiflo units. Installed in the early 1970's, this system services a four bedroom home in Wisconsin on the shores of the St. Croix River, overlooking Bayport, MN. Because of the high slopes, the site has limited area; with room for only one drain field row. To this day, this unit is working flawlessly, sending only 99.9% clean effluent to the drain field. The home owners are an integral part of the proper maintenance of their system.
