Did you know
  • Removing Fremont's 1913 Ballville Dam in 2018 cost about $12 million — roughly $15 million less than repairing it would have — and reopened 22 miles of the Sandusky River.
  • An angler snagged a lake sturgeon above the old dam site in spring 2019; ODNR biologists said it was likely the first one seen there in about 150 years.
  • More than 11,000 freshwater mussels of 14 native species, including purple wartyback and round pigtoe, were hand-relocated upstream in the summer of 2017 before the dam came down.
  • Fremont's water never touches a well: it is pumped out of the Sandusky River into a reservoir, then runs downhill by gravity to the treatment plant on Tiffin Street.
  • Every Fremont water and sewer connection carries a separate line-item surcharge for EPA-mandated improvements on top of the normal rate — $7.77 a month on the water side and $6.95 on the sewer side for a typical in-city…

History6
  • 1913Ballville Dam built on the Sandusky River by the Ohio Power Company, roughly 420 feet wide and 35 feet tall.
  • 1959The City of Fremont purchases Ballville Dam and begins using its impoundment as a drinking water supply.
  • 2013Fremont opens a new off-stream water supply reservoir, taking over the storage role the dam pool had served.
  • 2017Ahead of the dam's removal, more than 11,000 freshwater mussels representing 14 native species, including purple wartyback and round pigtoe, are relocated upstream.
  • 2018Ballville Dam demolished over roughly 20 working days, following a 2017 pilot notch cut. Removal cost about $12 million against an estimated $27 million to repair and upgrade the aging dam, and…
  • 2019An angler lands a lake sturgeon upstream of the old dam site — the first known sturgeon there in roughly 150 years.

Treatment & pressure

How it is treated

Fremont's source is the Sandusky River, classified as surface water. Water is pumped from the river into the Fremont Reservoir and flows by gravity from the reservoir to the Fremont Water Treatment Plant at 1113 Tiffin Street. Treatment is conventional surface-water practice — filtration (turbidity…
