City of Toledo WWTP Improvements
1991-Present
Issue 11 - Wastewater Treatment Plants
Description:
Containing an average capacity of 100 mgd, the Toledo Bay View WWTP treats much
of the City of Toledo and all of part of six adjacent jurisdictions. The plant has treated
an average daily flow of 73 mgd over the past decade, which is 11 mgd less that the
previous decade. This reduction can be directly attributed to sewer system
improvements and improved flow monitoring.
Combined sewers function in older parts of the city including CSOs along the
Maumee, Swan Creek and the Ottawa Rivers. Improvements to the area include an
interceptor along the Tenmile Creek, Swan Creek CSO tunnels, and continuing sewer
projects to reduce overflows. WWTP improvements have enabled the plant o meet
its NPDES Permit requirements, improve solids handling capabilities, increase wet
weather capacity, and decrease residual chlorine and ammonia in the plant’s effluent.
The Toledo WWTP is primarily concerned with reducing the extra water through the
system but the improvement projects will take upwards of $400 million and 20 years to
finance, design and build.
City of Toledo WWTP Residuals Management
1989-Present
Description:
The City of Toledo currently contracts with N-Viro Soil to manage the City's WWTP
residuals. N-Viro takes in 75% of the city's dewatered biosolids and has made close
to 70,000 tons of N-Viro Soil in the past year (2000). 500,000 tons of product have
been made since the start of the facility at N-Viro's Bayview Facility in Toledo since
1989. The facility has also teamed up with the Kurtz Bros., a firm that manages the
leaf collection in the area, to provide a new soil for distribution and sale.
N-Viro provides waste management technologies, support services, bio-mineral
treatment technologies, and produces biosolids. It collaborates with federal and state
agencies and agriculture research organizations to study product safety and
environmental contaminants.
