The City of Reedsburg’s wastewater
treatment plant was placed in service in 1939. Over the
years, the facility has been modified and expanded as
the community has grown and regulatory requirements have
changed. The plant currently has a 1.9 MGD capacity and
utilizes a hybrid process, incorporating both trickling
filter and activated sludge biological processes. In
addition to providing wastewater treatment to city
residents, the plant receives flow from a milk
processor, cheese manufacturer and a metal plating
facility.
| Since 1990,
the following plant modifications have been
undertaken to increase capacity and to meet new
regulatory requirements. |
- Flow Disinfection – In 1990,
the chlorination system was replaced with an
ultraviolet (UV) disinfection system.
- Treatment Plant Expansion – In
1992, the capacity was expanded by adding an
intermediate clarifier, an additional final
clarifier and a new primary gas-mixed heated
anaerobic digester. The project also included
flood proofing, emergency power and construction
of a public works garage.
- Solids Dewatering and
Stabilization System – In 1996, a new solids
handling facility was constructed which produces
Class "A" sludge.
- Phosphorus Removal – In 1997,
the city installed a chemical feed system to
reduce the effluent phosphorous concentration to
meet a new WDNR requirement.
- Laboratory Instrumentation and
Controls – Numerous improvements have been made to
improve operation including construction of a new
laboratory and office facility and installation of
new instrumentation and control equipment.
