Beginning this week, Schwind Trucking will be hauling wastewater biosolids in closed tanker trucks to agricultural fields.
Schwind will be removing the biosolids from the large open-air storage tank located at the city wastewater treatment facility on Oborn and Shearer streets.
It will take approximately two weeks to completely remove the biosolids from the tank and apply them as a soil conditioner and fertilizer.
Over the past four years, grit and debris have built up in the bottom 5 feet of the biosolids digester.
While the city completed some improvements to help extend the amount of time needed between digester cleanings, it is currently running inefficiently.
Due to the current level of solids built up, the city will be required to clean out the digester, perform a routine inspection and complete any required maintenance.
This digester cleaning and restart process, along with the biosolids pumping and hauling, will create odor at the wastewater treatment facility that will become airborne.
In the next few years, city staff will be investigating improving solids removal at the wastewater treatment facility prior to their introduction into the digester. However, capital improvements in the range of $250,000 may be needed to accomplish this.
