1. Are Is there an existing 6” tap and valve on Valle Verde’s water main, then reduced down to the 1” existing meter?

A: This is a question for Valle Verde. This is not relevant to the work in this contract. Valle Verde installed a 1” tee for Nogales connection. For the purposes of this contract a 6” meter and line will be installed that the contractor will connect into.

2. What is the existing size of Valle Verde’s water main?

A: It is believed to be 6 inches, but should be confirmed with Valle Verde. COR has inquired with Southwest Utilities but not received a full email response, but was on phone told by Southwestern Utilities they may not tell us because it could be proprietary. So we may or may not get an answer. Work in this contract begins after the service line and meter.

3. Will a pressure test on the ARV’s or any component of the ARV plumbing be required?

A: Does not need to be tested. But if installed, and waterline has not been tested, contractor shall ensure the unit is adjusted to a higher relief pressure for the duration of the test and then reset to the proper operating pressure when done. If the new ARV can’t be adjusted to a higher test pressure, the unit should be removed, and opening to be plugged during the hydrostatic pressure test.

4. We assume the old FS water system or connections will not require psi testing.

A: Correct. Only the new sections will need to be pressure tested.

5. Please identify the existing FS water distribution system pipe material where the new 6” water service line will be tied into.

7. Are there any specific means & methods the USFS expects for flushing or eliminating PFA’s in the existing system that will be reused?

9. Can the USFS provide a ROM for the project?

A: the Contracting Officer will provide the expected cost range of the project.

11. Has this project been approved by the Valle Verde for connection?

A: Valle Verde Water Company is aware of the proposed connection. VVWC installed the 1-inch water meter. The upsizing of the 1” meter to a 6” service line and meter has been applied for but there is not a response yet.

12. What is required for fire protection when the water system is down for connection & disinfecting/flushing?
