ELDORADO —
By July Eldorado's sewage treatment plant should have its first overhaul in 30 years completed.
The $1.5 million project was over a year in the works when the construction phase began about three months ago. Now nearly every day workers are at the plant replacing or renovating everything from the motors inside the activated sludge plants to a new roof and doors on the lab building.
The components of the rotating biological contractors that remove ammonium nitrate have been replaced and rewiring the RBC is yet to be done. The RBCs had been rusting out, Street and Wastewater Superintendent J.B. James said.
"These run 24/7. For 30 years they had never been shut off," James said.
The RBCs are shut off for now during the renovation.
The entire plant is being rewired, the motors and gears beneath the water in the sludge plants are being replaced and everything on top of the water in the sludge plants is being sandblasted and painted, Eldorado Sewage Plant Operations Manager Jay Woolard said.
The joints in the air lines leading to the sludge plants have rusted and are leaking air. They are being dug up and the joints are being fixed.
The motor control center in the lab has been rewired and a new generator has been installed.
The lab's flat roof was leaking badly and it has been replaced with an angled metal roof. The drop ceiling of the lab is also being replaced.
While the work is underway and certain parts of the plant are having to be temporarily shut down, the water passing through it continues to meet Environmental Protection Agency standards, Woolard said.
"The EPA was out this morning and got a sample," Woolard said.
Jim Guard of Brown-Roberts Engineering is ensuring all the work is being done correctly.
"This is going to be first class when it gets there," Guard said.
"It should be a fine plant again when it gets done," Woolard said.
The plant Tuesday was moving 1,402,000 gallons of sewage over 24 hours. The plant takes water into the two activated sludge plants, moves it to the two rotating biological contactors and then to the final clarifier tank before expelling it into a drainage ditch.
