If the superintendent deems any such guards, fencing or covering inadequate, the person making such excavation shall place such necessary or additional guards, fencing or covering as the superintendent or engineer may direct.

B.    Persons conducting any part, or all of the operations connected with the work as set forth in subsection A, will be held responsible for any failure to respect, adhere to or comply with all ordinances, resolutions and laws governing, controlling or limiting in any way the action of those engaged upon the work.

(Ord. 78 § 13, 1972)

13.28.140 Penalties.

Any person performing work subject to the provisions of this chapter shall notify the building inspector when the work will be ready for inspection and shall specify in such notice the location of the premises. If the inspector finds the work or material used is not in accordance with the provisions of this chapter, he shall notify the person doing the work and also the owner of the premises by posting written notice upon the premises and such posted notice shall be all the notice that is required to be given of the defects in the work or material found in such inspection, and a copy of such notice shall be kept on file in the office of the building inspector. If such defects are not corrected within thirty days of such posted notice, the building inspector or engineer, if in their opinion such defective work is detrimental to the public sewerage system, may order or cause the defects to be corrected, and the actual cost of such correction shall be chargeable to the owner as a service charge and shall be a lien upon the property served by such side sewer. Any additional inspection shall be paid for by the contractor by posting a fifty-dollar fee with the city and any funds remaining shall be returned to the contractor within thirty days after acceptance of the work. (Ord. 78 § 14, 1972)

13.28.150 Inspection before trenches are filled.

No trench shall be filled nor any connecting sewer covered until the work from the place where the same connects with the public sewer, or other outlet, to the point where it connects with the iron pipe, or other plumbing of the building or premises to be connected has been inspected and approved by or under the direction of the superintendent and until the same has been made in all respects to conform to the provisions of this chapter. (Ord. 78 § 15, 1972)

13.28.160 Inspector’s right of entry.

The superintendent, engineer, or their designated inspectors or authorized representatives shall have free access to all buildings or premises for the purpose of examining any and/or all private sewers or drains and of ascertaining whether the provisions of this chapter are being complied with, and for such purpose shall, at all reasonable times, have the right to enter and inspect such buildings, and it is unlawful for any person to prevent or attempt to prevent any entrance or inspection or to obstruct or interfere with any such officer while engaged therein. (Ord. 78 § 16, 1972)

13.28.170 Work in public streets—Bonded contractor.

No person shall install side sewers in any public thoroughfare or right-of-way and make connection to the city’s sewer unless he is bonded to do such work to the city, and has adequate liability insurance. Bond and insurance forms along with opening permit issued by the city must be in the possession of the person working in right-of-way. The superintendent has authority to waive this requirement in the event of emergency. (Ord. 78 § 17, 1972)

13.28.180 Restoration of roadways.

All work within the limits of any street or public place must be prosecuted to completion with due diligence, and if any excavation is left open beyond a reasonable time, in the opinion of the city, the superintendent or engineer may cause the same to be rebuilt and the street to be restored forthwith and any costs incurred in such work shall be charged to the contractor in charge of such work, or to the property owner and the actual costs may be added to the bill for sewer services and shall be a lien upon the property served by such side sewer. (Ord. 78 § 18, 1972)

13.28.190 Quality of materials and standards of construction.

All materials and standards of construction shall be subject to the approval of the city or its authorized representative and shall conform to the latest revision of the rules and regulations of the city. (Ord. 78 § 20, 1972)

13.28.200 Air testing.

A.    The contractor shall furnish all facilities and personnel for conducting the air-acceptance test under the observation of the engineer. The equipment and personnel shall be subject to the approval of the engineer.

B.    The pipe installation shall be tested with low-pressure air. Air shall be slowly supplied to the plugged pipe installation until the internal air pressure reaches 4.0 pounds per square inch greater than the average back pressure of any groundwater that may submerge the pipe, if:

1.    The total rate of air loss from any section tested in its entirety between manhole and cleanout structures does not exceed 2.0 cubic feet per minute; or

2.    The section under test does not lose air at a greater rate than 0.0030 cubic feet per minute per square feet of internal pipe surface.

C.    If the pipe installation fails to meet these requirements, the contractor shall determine at his own expense the source or sources of leakage, and he shall replace all defective materials or workmanship or repair them to the satisfaction of the engineer. The extent and type of repair which may be allowed as well as results shall be subject to the approval of the engineer. The completed pipe installation shall then be retested and required to meet the requirements of this test.

D.    Side sewers may, upon approval of the city building inspector, be tested for visible leakage before backfilling by inserting a removable test plug at the lower end of the line and filling the line with water to its highest point. The contractor shall make this test before calling for inspection so that the inspector can observe and approve the installation in one visit. A tee shall be provided in the sewer for insertion of the plug and shall be capped tightly and securely against back pressure upon completion of the test.

(Ord. 78 § 21, 1972)

13.28.210 Exfilteration test.

A.    Exfilteration test shall be used only if specifically authorized by the engineer. Leakage, unless otherwise provided for in the special provisions, shall not exceed the provisions that follow. Leakage after backfill shall be no more than five tenths gallon per hour per inch of diameter per one hundred feet of sewer pipe, with a minimum test pressure of six feet of water column above rounding ground water table whichever causes the greater head on the pipe. The length of pipe tested shall be limited so that the pressure on the invert of the lower end of the section tested shall not exceed sixteen feet of water column. For each increase in pressure of two feet above the basic six feet measured above the crown at the lower end of the test section, the allowable leakage shall be increased by ten percent.

B.    Side sewers shall also be tested for their entire length from the public sewer in the street to the connection with the building plumbing. Testing of side sewers shall be as required by the local sanitary agency. Within the boundaries of the city, in no case shall testing be less thorough than that of filling the pipe with water before backfill and visually inspecting the exterior for leakage. The decision of the engineer as to acceptance of the side sewer shall be final.

C.    The contractor may fill the pipe any time up to twenty-four hours prior to the time of exfilteration testing to permit normal absorption into the pipe walls.

D.    It shall be the contractor’s responsibility to determine the level of the water table at each manhole. This may be done by installing a pipe nipple through the manhole wall or by some other means satisfactory to the engineer.

Allowable Leakage in Gallons per 100 Linear Feet of Sewer per Hour (Based on 0.5 gph/100 feet of pipe per inch of diameter plus 10% for every 2 feet of head above 6 feet)
