4.1 General Utility Line Construction Methods:

a. Wire Installations on City Utility Poles.
No wire, cable, or other attachments shall be permitted on any City-owned pole without approval of the City of Hawarden, a pole attachment agreement, and the payment of rents as required by said agreement.
b. Excavations.
No excavation in any street, avenue, alley or public grounds for any pipe, wire, or other purpose shall be made without first receiving a digging permit from the Public Works Department. Said Permit shall be applied for 72 hours before any planned excavations. Emergency excavations shall be requested immediately after it is determined public property excavation is necessary.
c. Protecting the Public.
The contractor shall be fully responsible to provide, erect, and maintain at all times, until final completion of his/her work, suitable and requisite barriers, signs and warning lights as may be necessary to insure the safety of the public and shall assume full responsibility for all damages sustained by any person or property due to carrying on of his work. All contractors will be required to provide the City with proof in insurance.
d. Inspection of Lateral/Service Line.
Before any service line pipe is covered for water or sanitary sewer it must be inspected by the Public Works Director or his designee. Any service pipe which fails to meet the requirements of these service rules, or any other ordinances of the City shall not be accepted and must be corrected or such service will be not be provided or discontinued and the installer and owner will be subject to a municipal infraction.
e. Backfilling of Public Property.
For backfill, only materials approved by the City shall be used. Pipes shall be backfilled completely under the pipe and along the haunches in uniform layers not exceeding six inches in depth up each side and up to a level of two feet over the top of the pipe. Above this backfill shall be laid and tamped in twelve-inch lifts. If located in the street surfaced area, the last 12 inch lift shall be road gravel. Each layer placed shall be uniformly mechanically tamped and compacted, so as to eliminate the possibility of vertical or lateral displacement. This tamping shall be required the full depth of the trench in the public right of way. Paving materials and dirt/grass shall be renewed or replaced at the owner's expense to the same condition in the right-of-way as existed prior to construction. If a concrete street, the concrete shall be pinned into the adjoining concrete and shall match the existing grade and thickness of the street/sidewalk concrete with a minimum of 6" thickness for the street and 4" for a sidewalk. A chip and seal or hot mix repair for a non-concrete street shall be done by the City Street Department for $50.
f. Interruption of Service.
If the Utility deems it necessary, the Utility may temporarily interrupt utility service to any customer or group of customers for the purpose of making repairs, changes or improvements upon any part of the Utility’s system. When practical, scheduled interruptions will occur during a period of minimal usage or will be pre-arranged and advance notice will be given to the customer.
