In addition, it reassigns some flow and number of connections within some of the phases & sections due to changes in the development's land plan. However, no additional active connections are being approved for any type of collection system as the downstream sewer limitations still remain as referenced in Special Condition 1.3. August 28, 2013 MODIFICATION (VERSION 1.8) Approximately 2,180 linear feet of 8-inch gravity sewer to eventually serve 46 single-family units as part of Compass Pointe Phase 4 Section 5 and the discharge of 9,660 gallons per day of collected wastewater into the Brunswick Regional Water & Sewer H2GO's existing sewerage system pursuant to the application received July 18, 2013 and additional information received July 24, 2013.
