I -j I J ] J ) .J J J .J J J J J J J J Connection of service lines to the watennain shall be made with an approved corporation stop. with the watennain tap being made at an angle of not more than 22 degrees from the horizontal. Expansion loops shall be directed downward ftom the tap. One and one-half and two inch service pipe shall have a 45 degree bend connected to the corporation stop to facilitate the downward .expansion loop. The.connection will be a wet tap unless authorized by the ENGINEER., his representative. specified in the "Special Conditions" Section 100 or on the plans. Unless otherwise indicated. service lines shall be installed on a straight line at right angles to the water main or property line as directed by the ENGINEER. ." Service lines shall extend for such distance beyond the curb stop as may be specified in the Contract. In the absence of specific requirements. the service line shall be tenninated at the property line. where .it shall be connected to an existing line or. in the case of undeveloped property. it shall be capped. plugged. or peened as approved by the ENGINEER. The flaring of copper tubing ends shall be accomplished only with the use of the proper size and type of tools as designed for the purpose. such as win provide accurate sizing and rounding of the ends. Tubing shall be cut squarely and all edge roughness shall be removed prior to flaring. All couplings shall be tightened securely. so the flared end fits snugly against the bevel of the fitting without leakage. The flared joint couplings shall be made up without the use of jointing compounds. 303.404 WET TAPPING A LATERAL TO AMAIN When tapping a lateral watermain or service to an existing watennain, the . CONTRACTOR shall be required to make connection to the existing watennain while the existing wat~nnain is under pressure (i.e.. wet tap) using an A WW A approved drilling machine. tapping sleeve "and tapping valve. Conductivity must be maintained from the main that was tapped to the new main by whatever methods necessary. A connection to a!l existing watermain by methods other than a wet tap can be done o~y " with approval of the ENGINEER or if specifically shown on the plan or "Special Conditions" Section 100. The CONTRACTOR shall verify the size of the existing watennain prior to ordering t.he fittings for the connection. 303.405 LOCATION RECORDS Each water service shall be marked at the property line by a 4" X 4" timber six feet to eight feet in length embedded four feet below grade. The 4" X 4" timber will be supplied by the CONTRACTOR. Careful records shalrbe kept cooperatively by the CONTRACTOR'S and OWNER's representative (ENGINEER or Inspector) as to size. type and location of service tap. and ties to the curb boxes to existing buildings. Copies of the service ties shall be forwarded to Dennis Alberts at the Roseville Utilities Department by the CONTRACTOR. 300-11 i i ~
