See Article 60.02.3., paragraphs A. and B. above for additional applicable requirements.

1. Copper Water Service Connections to Water Mains

Water service connections to pre-existing operational water mains shall be made under line pressure in the main.

Connections of 1 inch corporation stops to ductile iron piping shall be made by directly tapping the ductile iron piping wall. Connections of 1-1/2 inch and 2 inch corporation stops to ductile iron piping shall be made using service saddles.

Connections of 1 inch, 1-1/2 inch, and 2 inch corporation stops to 12 inch or smaller nominal diameter HDPE main pipe shall be made using service saddles.



Connections of copper water services to operational HDPE main pipe larger than 12 inch nominal diameter shall be as shown on the Plans or as specified in the Special Provisions.

2. Copper Water Service Installation

Water services shall be installed perpendicular to the street centerline whenever possible.

Copper tubing shall be installed without kinking or other damage, and to the satisfaction of Doyon Utilities’ Authorized Representative. Kinked or otherwise damaged copper tubing, as determined by Doyon Utilities’ Authorized Representative, shall be discarded and replaced at Contractor expense.

Wherever possible, copper water services shall be installed in continuous sections with buried joints only as specifically shown on the Standard Details or directed by Doyon Utilities’ Authorized Representative. If required, underground joints in copper tubing shall be flare connections. Underground soldered joints and/or unions shall not be permitted.

If a project includes new water main and new water services connected to the new main, new water services shall be completely installed before new water main open bore flushing, pressure testing, and disinfection are completed, and shall be flushed, pressure tested, and disinfected in the same operations as the water main.

For copper water services stubbed out for buildings that are under construction, the water service line shall be installed from the curb stop to a point up to 5 feet inside the building footing line that is acceptable to Doyon Utilities’ Authorized Representative and, at that point inside of the footings, extended upward to 2 feet minimum above the finished grade.

For copper water services stubbed out for future use, a copper bleeder line with a diameter equal to the service line diameter shall be connected to the curb stop, extended above the finished grade in a non-traffic area designated by Doyon Utilities’ Authorized Representative, and attached to a 4 inch by 4 inch post as shown on the Standard Details.

Bleeders or day-lighted service line extensions shall be used for open bore flushing, disinfection, and sampling of water services for bacteriological testing. After satisfactory bacteriological testing results are obtained from new water services, all chlorine solution shall be flushed out, and bleeders and day-lighted services shall be closed off above grade as shown on the Standard Details and as directed by Doyon Utilities’ Authorized Representative.

3. Copper Water Service Bedding

Unless called out otherwise on the Plans or Standard Details, specified otherwise herein, or directed otherwise by Doyon Utilities’ Authorized Representative, pipe bedding for copper tubing shall meet the requirements of Class “B” bedding per Division 20 - Earthwork.

4. Copper Water Service Thaw Wires



A #2 stranded copper thaw wire shall be installed as shown on the Standard Details. Thaw wires shall be of lengths to extend one foot minimum above finished grade to provide accessibility for future use.

5. Copper Water Service Insulation

All copper water services shall be insulated with board insulation 4 inches thick (two each 2 inch thick layers) by 4 foot minimum width, centered over the water service and extending the full length of the water service plus a minimum of 2 additional feet at each end. To the extent possible, the bottom of the insulation shall be 6 inches above the top of the water service. Board insulation shall be coped as necessary to fit snugly around key boxes to the satisfaction of Doyon Utilities’ Authorized Representative.

F. Water Line Separation Requirements from Sanitary Sewers and Storm Drains

All water lines, including mains, fire hydrant assemblies, fire lines, and water services, shall be constructed to meet all separation requirements of 18 AAC 80.020, or the following requirements, whichever are more stringent:

1. Water lines shall be installed at least 10 feet horizontal out-to-out from parallel sanitary sewers, storm drains, and sewer and storm drain appurtenances (including but not limited to gravity sewer mains, gravity sewer services, sewer manholes, sewer clean-outs, wastewater lift stations and force mains, storm drain mains, catch basins and catch basin leads, and storm drain manholes).

2. Water line pipe at sanitary s
