B. PROJECT BID

1. This project includes a BASE BID and OPTIONAL BID.

a. Optional Bid includes the complete installation of a 6-inch Reduced Pressure Principle Zone Assembly, if required, after consultation with Valle Verde WC. The following condition and test can determine if the RPPZ assembly will be necessary.

1) Condition:

a) Cross Connection device necessary after review of existing and new cross connection control devices on the Nogales Ranger Station Water System Site Plan. If determined there is no adequate cross connection control protection, the RPPZ assembly shall be installed.

b) The existing distribution system includes existing RPPZ assemblies on the landscape irrigation system and the fire hydrant protection units.

New double check valve assembly will be installed for existing 2-inch overhead fill station (with no hose connection) with air gap.

2) Test:

a) Contractor shall determine if PRV is required after coordination with Valle Verde Water Company and verification of static water pressure at the meter location.

b) The ideal static pressure range is typically 40-80 psi. If the static pressure exceeds 80 psi, a PRV will be required by plumbing code.

C. BASE BID: The work consists of:

1. Connect to Valle Verde WC water main off of government property within utility easement. The following coordinate is location of existing 1-inch water meter:

Latitude: 34.425960

Longitude: -110.962112

Constructing approximately 115 lineal feet of new 6-inch potable waterline from nearby private regulated water system known as Valle Verde Water Company. This water company operates and is managed as a private water company under Southwestern Utility Management.

The waterline connection is to connect Valle Verde Company to the Nogales Ranger

WATERLINE CONNECTION Page | 4 | 01 11 00

Station distribution system for potable water and fire protection system. The existing well at Nogales Ranger Station will be disconnected as the water source.

2. Furnish and install a new 6-inch water meter as recommended or purchased from Valle Verde Water Company to replace the existing 1-inch water meter to accommodate the ranger station’s existing 6-inch water main (combination potable water and fire protection system).

3. Install approximately 115-lineal feet of 6-inch potable water line to connect to existing Nogales water distribution system at location, AS SHOWN ON DRAWING.

4. Carefully remove all existing fencing crossing new waterline installation and make all necessary repairs and/or replacements, as needed, to return to original functionality.

5. Furnish and install components to cap existing 8-inch waterline after tee to Ruby House service connection, AS SHOWN ON DRAWING. Service to Ruby House shall remain functional.

6. Furnish and install components to cap 4-inch waterline to disconnect the gravity feed from the tank, AS SHOWN ON DRAWING. The water service connection providing water to sprinkler system for warehouse shall remain functional.

7. Furnish and install 2-inch double check valve assembly (DCVA) between the potable water system and the overhead fill station at the warehouse, including fittings for future maintenance and shut-off such as valves and unions, AS SHOWN ON

DRAWING.

8. Furnish and install 2-inch air release valve and valve box at location, AS SHOWN

ON DRAWING.

9. Furnish and install 2-inch post flushing hydrant including shut off valve and valve box at location, AS SHOWN ON DRAWING. There will be a dead end main at the end of the existing 4-inch waterline.

10. Furnish and install all fittings including valves, valve boxes, and unions to allow isolation for major fittings and/or equipment for future maintenance purposes.

D. OPTIONAL BID. The work consists of:

1. Furnish and install new 6-inch Reduced Pressure Principle Zone (RPZ) assembly (testable) at location AS SHOWN ON DRAWING.
