Waterworks Park occupies a bend in the Huron River just north of the Visteon Plant, west of Catherine Street (Ypsilanti). The park was the site of the City of Ypsilanti's water treatment plant until the City and surrounding Townships joined the Detroit Water Authority's service area in the early 1990s(?).

The park is relatively underused and overgrown at present, lacking good access to any neighborhood. However, a footbridge connects the park to the Water Street Redevelopment Project area to the north, the park will soon be connected to the County's Border to Border Trail, and there is some talk of pairing with the Ann Arbor Area Disc Golf club to develop a frisbee golf course in part of this park, so it will hopefully see more use in the future.
