§ 15.01.685. Secondary water service lateral connection.

Secondary water service laterals shall be constructed with materials specified and at the locations shown on the standard drawings or at the actual location established during construction. This section covers the installation of the service connection from the main to right-of-way line.

1.

Service saddle specification (for use with C900, C905, and C909 PVC plastic pipe). All service clamps shall be of a "full encirclement design," and shall be I.D. controlled, which design will eliminate the possibility of pipe crushing due to the over-torquing of the nuts upon installation.

A rigid liner shall be used inside of tubing at the compression fitting on a one-inch single service connection. No rigid liner will be required inside of tubing at compression fittings on one-and-one-half-inch or two-inch service lines.

All service clamps shall be manufactured of brass cast in conformance to AWWA C800, General Section 1, Paragraph 1.2 (ASTM B62).

The two sides of the clamp shall be held together by high quality silicon bronze hex bolts (in sizes one-inch and larger) or silicon bronze slotted screws (in sizes smaller than one inch). No dissimilar metals shall be allowed at this point thus eliminating the possibility of galvanic corrosion.

All service clamps shall be Romac 202NS or Romac 305 Series for fourteen-inch or larger pipe.

2.

Polyethylene tubing. Pipe for the transmission or secondary water from main to utility box shall be polyethylene CTS tubing. Polyethylene CTS tubing shall be manufactured in accordance with the standard specification for Polyethylene PEP plastic tubing as issued by the American Standard for Testing and Materials under ASTM D 2737 and AWWA C901.

Material designation code:	Polyethylene PE 3408
Plastic extrusion compound:	Type III, Class C, Grade 34, as defined by ASTM D 1248

 

Standard pipe dimension ration CTS (SDR 9) two hundred psi pressure rating.

All tubing for service lines shall be cut and installed in a neat and workmanlike manner by a method recommended by the manufacturer.

Tubing shall be WESTFLEX PE 3408 Gold Label or approved equal, purple in color.

3.

Compression connections. The interior surface of the coupling nut, including threads, shall have a baked on, fluorocarbon coating to reduce assembly friction and prevent the gasket from turning and twisting during tightening. The nut shall bottom on a cast or machined shoulder on the body when properly assembled. This design will provide a visual check to assure connection is properly assembled.

The sealing gasket shall be of molded synthetic rubber (ASTM D2000) with molded-in-place bronze spring (ASTM A134 Alloy #6) to eliminate the possible cold flow of the gasket between the pipe and fitting. A gripper band of hardened stainless steel (ANSI Type 401) shall be fitted in to the gasket. When the gasket is compressed, it will cause the gripper ring to distort the pipe-giving the fitting a high resistance to pull-out. The gripper band shall overlap itself to prevent cold flow of the gasket into the cavity under the band.

When Mueller 110 compression fittings are used with PE pipe, stainless steel pipe stiffeners are required to eliminate cold flow of plastic pipe.

All fittings are to be for CTS polyethylene pipe.

The minimum pull-out load for the fitting when used with PE pipe shall be as follows for each given size:

Size	Minimum Pull Out (ft-lbs)
1"	400
1½"	500
2"	500

 

Mueller 110 compression coupling and fittings or approved equal are to be used on all PE plastic pipe installations.

4.

Service fittings. All service fittings, such as brass tees, and brass ells, shall be Mueller Insta-Tite connections or approve equal.

5.

Ball straight service valve. All components shall be manufactured of brass cast in conformance to AWWA C-800, General Section 1, paragraph 1.2. The valve shall have a strong, reliable ball/stem connection that provides strong, reliable performance and resists breakage. The stem design must be totally blow-out-proof to prevent separation and assure dependable safe operation. The stem shall have double O-ring seals supported in precision-machined grooves and provide secure, leak-tight sealing. The end pieces shall be O-ring sealed to provide additional protection against leaking. The ball shall be manufactured of 85-5-5-5 waterworks brass; no other composition will be accepted. The ball shall be fluorocarbon-coated for ease of operation. The valve shall be quarter-turn valve; and the fully open and closed positions shall be controlled by check lugs integrally cast on body to assure positive action. The valve shall have a lock wing to permit locking the valve in the closed position. The inlet shall be a compression connection; and the outlet shall be F.I.P. thread for one-and-one-half-inch and two-inch and standard meter coupler for one inch.

All brass castings shall conform to ASTM B62, latest revision, Standards for composition brass or ounce metal castings of 85-5-5-5. The valve shall be manufactured and tested in accordance with ANSI/AWWA C800, latest revision. A notarized certificate stating compliance with the Standards may be required. All component parts, body, key, washer, nut and tube nut, shall have the same metal analysis. The valve must maintain a working pressure of 300 PSIG.

All fittings are to be CTS (copper tube size) size, used on CTS polyethylene pipe. No IPS polyethylene pipe or fittings will be accepted.

Ball straight service valve shall be Mueller B-25170 ball valve for one-inch connections and Mueller B-25028 for one-and-one-half-inch and two-inch connections.

6.

Service box. Service box shall be a standard green, fiberglass irrigation box with cover. Service box shall be installed over the valve and hose bib. A sign shall be attached or embossed to or on the cover indicating as follows: "IRRIGATION." Box shall be Carson 1220-12-4 or 1419-12-4 series utility box with lid recessed and shall be provided with Waterworks Pentagon Head locking device or approved equal.

7.

Meter idler. All service connections shall include two C38-44-2 MIP X STRT meter couplings on both sides of a #4 brass meter idler.

Pipe for the transmission of secondary water from the meter coupler to the homeowner's property line shall be Schedule 40 brass nipple with cap. Pipe shall be manufactured to meet the requirements of 85-5-5-5 waterworks brass. No joints will be allowed under sidewalks or other paved surfaces.

8.

Hose bib. All hose bibs used in the service connection assembly shall be a three-fourths-inch Arrowhead I-400 inverted brass hose bib or equal,

9.

Location of stub pipes. Three notches on the front corner of the curb shall mark the location where the secondary water service crosses the curb. Each cut shall be one-eighth-inch—three-sixths-inch deep and three-eighths-inch—one-half-inch apart.

10.

Service pipe installation. The polyethylene service pipe shall be installed by use of directional boring under all existing paved surfaces. Where subsurface materials or conditions will not permit installation by this method, open trenching will be permitted with the approval of the public works representative/engineer. Open trenching may by used in new streets not yet paved.
