MNRWA Letter of Support for Bliss Project 2020.docxDear City of Scandia,
Over the past two months I have personally been in your city looking at ways to solve the wastewater
treatment issue you’re having. I have looked deeply into the problem and have done hours of research
by calling engineers, vendors, and contractors along with my knowledge of wastewater believe this can
be fixed.
Wastewater treatment needs to be evenly distributed amongst the system allowing effective even
treatment. However in Scandia the flow is extremely heavy and overloaded to one side of the treatment
plant. When this happens the problem is solely over saturated soils. The soils of your treatment system
eventually become too full of waste and can no longer filter efficiently.
The fix option to solve an over-saturated soil problem is to even out the flow. #1 is completely
overloaded while #4 is completely under loaded. This comes from poor installation or design and can be
corrected. From my findings what needs to happen to create the best treatment possible and longevity
to Scandia wastewater system a diffuser needs to be installed. A diffuser is a system that will slow down
flow to #1 while pushing wastewater evenly to #2, #3, .
Installing diffusers will allow the treatment plant to work to its full potential. I recommend digging up
and installing these diffusers like this #1 capping and drilling a hole in the cap to allow water through yet
building up enough pressure to push into #2. Then capping #2 and drilling a hole in the cap to allow
water through evenly and give the system enough pressure to keep moving water down the line to #3 &
#4 to evenly distribute all wastewater throughout the system.
In my opinion Scandia’s wastewater treatment plant can be fixed/ upgraded to adequately treat
wastewater thus prolonging the life of the system and saving the city money for future failure of the
treatment plant in repairs.
