The 10 mgd treatment plant expansion planned for 2012 will replace tube settlers in
existing basins with dissolved air flotation equipment. Four new filter basins will also be
constructed. Utilization of existing basins inside the treatment facility will make the next
10 mgd plant expansion relatively inexpensive.

Table 5.1 shows preliminary cost estimates for the planned expansion. Costs and
capacities shown in Table 5.1 are for the total project. The cost of the plant expansion
will be shared among the three Districts that own the SCFP. ELCO would pay its
proportionate share of project costs based on its relative water use at the time of
construction.
