Wastewater Treatment Plant Timeline
- 1940
 The Bryan Wastewater Treatment Plant with a capacity of .85 MGD (Million Gallons per Day) is placed
in operation.
- 1962
 Plant capacity doubled to 1.9 MGD
- 1971
- An estimated 45 million gallons of untreated or partially treated wastewater were being discharged per year. Two
2.5 MGD holding ponds and two 7.5 acre polishing ponds were constructed to help manage
high flows.
- 1974
A chemical feed building was added to enable the plant to remove phosphorus which was now being limited
by the Ohio EPA.
- 1975
A liquid sludge applicator truck was purchased and the plant began applying sludge to crop fields.
- 1984
Ohio EPA aproved an industrial pretreatment program designed to eliminate upsets at the treatment
plant and ensure that the plant could meet it's discharge permit.
- 1988
Major improvements were made at the plant that increased the capacity to 3.1 MGD. A higher level of
treatment was achieved including ammonia removal.
- 2005
- A state of the art sludge dewatering facility was constructed. Liquid sludge is processed with
centrifuges and a natural gas fired sludge dryer that produces a class "A" sludge that is considered
more environmentally friendly than the previous class "B" sludge that was produced.
