Based on this calculation and the preliminary building layouts, we will need a 4” sanitary sewer connection for each building type. The leasing center will need a 6” sewer connection for pool backwash. Please see the table below for domestic water tap/meter size as well as sanitary size for each building type. These tap sizes do not include any fire protection load.
