A saddle tap shall be used when connecting the proposed 2” water service to the existing water main. 2. Exploratory excavation must be performed to confirm that there is a cap with thrust block on the end of the existing water main that will be tapped for the new service. 3.

Tracer wire shall be required in accordance with the CWD Specifications. 5. The 2” water service line and all appurtenances shall be considered private and the responsibility of the property owner. 6. The South Burlington Water Department will require an easement to each curb stop outside of the City ROW for access only. Maintenance and repairs are the responsibility of the property owner. 7. The customers connected to the proposed 2” line may be subject to water quality degradation due to the length of the service line that will connect to an existing dead-end main. The SBWD will only be able to flush up to the last hydrant on Windswept Lane to aid in improving water conditions. Use of the fire hydrant on Windswept Lane will result in significant pressure fluctuations and the risk of discolored water on the proposed 2” service line. 8. Connection fees, allocation fees, meter and backflow requirements in accordance with the City of South Burlington Water Ordinance shall apply to this project. 9.
