The DNR will accept public comments on the plan through June 17, 2009.
With the proposed improvements, Robertson said, the plant will be capable of meeting discharge standards and providing adequate capacity for future growth. The current residential user rate is $35 per month based on an average use of 3,600 gallons. New rates are projected to be about $46 per month if all grant applications are successful. The project cost is estimated at $5,439,000 and will be financed using either a Community Development Block Grant for Public Facilities, a Wisconsin Clean Water Fund Loan or a Rural Development Loan.
Proposed improvements include: building a new headwork facility with screening and grit removal; new septage receiving facilities; a new selector basin; new splitter box structures; two new final clarifiers; a new chemical feed system; a new return activated sludge pumping station; a new ultraviolet disinfection system; two new aerobic digesters; a new transfer pump and blower building; sludge storage capacity expansion; a new Supervisory Control & Data Acquisition (SCADA) system; site work; and restoration.
