It became apparent in the early 1990's that the town of Milo could no longer dispose of its untreated sewerage by allowing it to flow into the Piscataquis River. The Trustees of the Milo Water District began to seek alternative methods for disposal and acquired the engineering firm of A.E. Hodsdon to help seek out a feasible solution.

     It was determined that an aerated lagoon system would best serve the communities needs and financial constraints. Also influencing the decision for the lagoon system was the availability of a parcel of land to accommodate the space requirements in the construction of a lagoon system.

    Today, operators of the plant are conducting a pilot study utilizing phragmite reeds for treating and reducing sludge volumes from the lagoons. Also underway is a project to introduce the bullhead ( hornpout ) into the lagoons to provide further mixing of the sludge layer that resides on the lagoon floors.
