The Frankfort Plant Board has approved moving forward with a project to replace the 130-year-old reservoir tanks, which have reached the end of their service life. Replacement of the existing tanks as is with two 4.6M gallon tanks and flat roofs is estimated to cost $8.15 million. The approved plan is to replace the two existing tanks with one tank for the foreseeable future (30-35 years, if not longer) given demand remains consistent. Once the final design is approved, the north basin will remain operational while the south basin is replaced. When the new tank is complete, the north tank will be removed, leaving area to build another tank in the future if demand requires it. The board is considering the following options for replacement.
