While homeowner habits have dramatically changed over the years, the design of conventional septic systems has not kept pace.  People today use much more water, disinfectants and other cleaning chemicals compared to even 10 years ago, but their conventional septic tank and drainfield disposal system have remained generally unchanged for over 50 years.

Waterloo Biofilter’s newest research article, published in the March 2010 edition of Environmental Science & Engineering Magazine, identifies the shortcomings of conventional septic systems with their ‘single barrier’ approach to wastewater treatment, and stresses the need for residential sewage treatment outside of the natural environment.  Septic systems that have separate and detached sewage treatment and sewage disposal components are more easily maintained and their performance is verifiable.  A Waterloo Biofilter system comprising a physical media filter followed by a fine sand or soil polishing and disposal bed, provides a preferred ‘multiple barrier’ solution that offers increased protection of soils and groundwater.
