Overall, twelve alternatives were developed comprising of varying sewer service options of gravity sewer, wastewater pumping station / force main, and low-pressure / grinder pumping system. The alternatives were evaluated for their advantages and disadvantages concerning reliability constructability, engineering and environments impacts, and community impacts. The selected alternative consists of 8,100 feet of gravity sewer, two wastewater pumping stations, 4,400 linear of feet of force mains, 6,000 linear feet of low pressure sewer, and over 300 individual grinder pump units.
