The Watertown Fire Department will be getting a new ambulance, which will help with the increasing numbers of medical calls to which paramedics respond. On Tuesday night, the Town Council unanimously approved the borrowing of $355,00 to pay for the purchase of a new ambulance. It will be paid off over five years with a total expected cost, including interest, of $402,925. The current ambulance, a 2016 GMC, has about 42,000 miles on it and will be kept as in reserve after the new one is delivered, said Fire Chief Bob Quinn. He said there is a lead time of about 8 months after ordering an ambulance.
