Sub-district I5 wastewater flows will be directed to Sub-district I4� The extension of sanitary sewer to Sub-districts I5 and I6 would result in the total peak flows entering Lift Station No� 2 exceeding the capacity of the lift station� Thus, the capacity of Lift Station No� 2 pumps would need to be upgraded from 400 gpm to at least 420 gpm before total sewer service expansion into Sub-districts I5 and I6� Sub-district I6 sanitary sewer improvements will consist of the extension of an 8-inch sanitary sewer and the construction of Lift Station I6 with a minimum pumping capacity of 115 gpm.
