Questions 164-167 refer to the following e-mail.

Dear Mr. Kim,

Because of a maintenance project, the water to Jigye Apartments will be turned off for several hours next Wednesday, 12 January. The interruption will begin at 11:00 A.M. Water service will be restored by 5:00 P.M. Please inform all of your building's tenants in advance about the interruption, as well as these general guidelines:

1. After the water is turned back on, air in the pipes may cause sudden bursts of water. You can fix this problem by running water slowly at first.

2. For any other issues that occur after water service is returned, call our Customer Service desk at the number listed on our Web site for your specific area.

3. Maintenance workers do their best to work quickly and finish as scheduled.

This service interruption is necessary to improve the quality of your water service in the future. We apologize for any inconvenience and thank you for your patience.

Best regards,

Pierrick de la Rue
