A new solar array has been installed at the Wastewater Treatment Facility in Watertown. This is an important step in improving operational efficiency and sustainability.
An investment of $886,050 was made to install the solar array which spans 2.5 acres. Financial support came from a grant of $300,000 from the United States Department of Energy and $24,759 from the Focus in Energy program of the state of Wisconsin.
Once the solar array is connected to internal electric grid of the facility, it will provide a substantial part of the energy needs of the facility every month. The plant typically spends $30,000 per month on electricity. It is expected that there will be savings of $4,000 to $5,000 per month, such that payback will be in less than 10 years.
News of such installations and their benefits for a city can be made known with Flyers and other printed materials created by local Print shops.
In addition, the Wastewater Treatment Facility is preparing to install a new sludge dryer. Critical energy capacity will be provided by the new solar array to help power the new system. As the new system provides renewable energy onsite, increasing demands for energy can be met cost effectively and sustainably. It will not provide energy external to the wastewater facility.
This new solar array highlights the commitment of the city of Watertown to environmental stewardship and fiscal responsibility.
