Dayton plans to spend nearly $ 8 million in an attempt to reduce the amount of phosphorus in its wastewater discharge.
Dayton, Ohio will spend about $ 8 million to try to reduce the amount of phosphorus in its wastewater discharge
These measures are taken to comply with state regulations and to avoid possible legal action.
According to the Ohio EPA, phosphorus from the city’s sewage treatment plant contributes to nutrient pollution in the lower Great Miami River. As a result, the city is upgrading its treatment facilities to comply with the new phosphorus limits by 2022, Dayton Daily News reported.
“Phosphorus and other nutrients contribute to poor water quality problems, including harmful algal blooms,” said Dina Pierce, spokesperson for the Ohio EPA.
In September, the City of Dayton commission approved a resolution authorizing the city manager to enter into a loan agreement to fund new phosphorus processing facilities.
The city is applying for a loan from the Ohio EPA Water Pollution Control Loan Fund, according to city documents. The construction project is expected to cost between $ 7.5 million and $ 7.8 million.
The project includes new chemical feed and storage equipment, new process-generated sludge thickening equipment, and other upgrades.
Dayton’s discharge permit for its wastewater treatment plant was renewed in 2016 and required the city to reduce phosphorus levels in wastewater effluent. The new limit requires the city to meet an annual average of 1 milligram per liter during the driest four months of the year, when city and county sewage treatment plants are the largest sources of phosphorus in the city. Great Miami River, according to Pierce.
There is no increase in sewer rates directly attributable to this project, but rate increases have taken place to meet sewage treatment needs, the Dayton Daily News reported.
According to Chris Clark, head of the waste recovery division, the state gave the city a generous compliance schedule to complete the design and construction of the phosphorus processing facility and assisted in the design review process.
With the design complete, the city goes through the bidding and award process.
