Lyons treatment plant now online
|WHERE THE WATER GOES
Once down the drain and in the sewer system, the water goes to a pump station on Mill Street, which pushes it to the treatment plant.
Large solids are removed from the flow using a fine screen.
The aeration tank mixes the wastewater with microorganisms that remove organic matter and ammonia.
The mixture of wastewater and microorganisms flows to the final clarifier where the microorganisms and what's left of the undigested effluent settles out as sludge.
Clear effluent from the final clarifier is disinfected with ultraviolet light and is discharged to the White River.
The remainder of the sludge from the final clarifier is pumped into the aerobic digester, where it is treated for up to 60 days. Bacteria break down the sludge, reducing its volume, odor and disease-causing bacteria and viruses.
The digested sludge is stored for subsequent recycle to farmland as a soil conditioner and fertilizer.|
October 12, 2011 | 08:03 AMLYONS TOWNSHIP — It's the after thought of modern society.
You shower, wash your hands, you flush the toilet, and the water goes down the drain, to the sewers to Ö where?
Well, for more than 550 homes and businesses in the town of Lyons, that waste water goes to the new Lyons Sanitary District 2 plant at 5996 Clearwater Court.
The sanitary district's three-member board had an open house for the new treatment plant with plenty of food and good weather. Unfortunately, not many turned out to see the new $4 million facility.
Because it's here that the dirty water from those Lyons homes and businesses is scrubbed and cleansed before it's returned to the environment.
To anyone who remembers the old blue metal pole building that housed the entire treatment facility, the new facility is quite a change.
The old building is gone, replaced by a freshly planted lawn and a sign identifying the new plant.
The Lyons Sanitary District officially broke ground for a new sewage treatment plant on July 1, 2010.
Construction of the new treatment plant took about one year to complete. It was officially put into service in September.
The new facility includes a processing building, an administration building, an operations building and a storage facility.
Also outdoors is the giant aeration tank, where waste water is mixed with bacteria which consumes pollutants and purifies the water, and a final clarifier, that allows the few impurities left in the water to settle out before the water flows to an ultraviolet disinfection tank before being released to the nearby White River.
According to information from Applied Technologies, the sanitary district's engineers, planning for the new facility began in 1995. That 1995 plan was amended in 2006.
The amended plan found the old treatment plant, which was built in 1980, was exceeding its capacity. The old facility was approaching 30 years old and had reached the end of its service life.
The Lyons district was able to secure a 20-year, $2.7 million loan at 2.2 percent interest, through the state Department of Natural Resources Clean Water Fund.
Country Estates, which is connected to the Lyons District treatment plant, secured a $1.45 million Wisconsin Rural Water Construction loan through the U.S. Department of Agriculture. It also received a $3.1 million grant for updating sewer pipes and manholes.
