Lake Community and Septic Sytems

Hi, my name is Paul Sutphen. I developed a wastewater conditioning system (WCS patent pending) for on-site tank and field septic systems.  The motivation for this effort comes from knowing that lake water is impaired by phosphorus loading.  The lake where I live, was once pristine before “cultural eutrophication” became a problem.  For example, in July of 1950, the water clarity was 12 feet.  This past year of 2014, the water clarity was 4 feet.  The difference in these two readings was caused by 60 years of watershed loading from the lake community served by septic systems.  The lake progressed from a part-time population to mostly fulltime population in that period.  The lake is typically dominated by blue green algae during the summer months of July and August.

In the photo of my waterfront, this picture taken in October shows a blue green algae scum.  Scum of this type of algae can be toxic and harmful to both animals and humans.   Clear Lake Technology (CLT) LLC, was formed as a research and development business to develop a technology to reduce septic influenced phosphorus loading from lake community homes.

The CLT technology of conditioning wastewater within the residence has been tested and shown to remove a significant amount of phosphorus before discharge to the disposal field.  If this technology was widely utilized within the lake community, a significant reduction in P loading from the watershed over time would occur.

This website will provide on-going information during a more than 1 year test period. Testing of a sister test site with a “black water” tank design will begin during the middle of the November.  We hope you will post comments and questions about CLT’s project.

I am presenting a paper at the November NALMS symposium on this system.  Check this website to see the presentation.  Also, I will provide links to other sources on the website.  Please be patient as this is the first time as a website developer.  I was not taught this in school 55 years ago!
