925.03 GENERAL SEWER CONSTRUCTION REQUIREMENTS.
(a) Responsibility for Construction. The Public Utilities Director shall supervise all the construction pertaining to the wastewater treatment facilities and all tests run on the collection system. He shall be responsible for offering and making recommendations for acceptance by the City Manager and/or Council.
(b) Sewer Construction. All sewer construction shall adhere to specifications and drawings in accordance with the Design, Construction and Materials Specification Handbook.
(c) Payment for Inspection of City-Initiated Work. Inspection for all sewer work initiated by the City shall be paid for from the Sewer Fund.
(d) Minimum Test Requirements. Maximum allowable infiltration shall be 100 gallons per mile per inch of diameter per twenty-four hour day. The Public Utilities Director or his/her authorized representative shall be present for all testing. The City shall not accept the responsibility of maintaining any new sewer unless the entire sewer has passed the infiltration test. The Public Utilities Director may require an exfiltration test or air test and closed circuit television inspection of all new sewers before acceptance.
(e) As-Built Drawings. Within thirty days after completion of the construction work on any part of the wastewater system, the contractor shall provide a complete set of certified, reproducible as-built drawings to the Public Utilities Director for all sewers constructed, including those constructed in subdivisions.
(f) Rules for Submittal of Subdivision Plans and Sewer Main Extensions.
(1) Improvements plans of all proposed subdivisions which include sanitary sewers shall be submitted to the Public Utilities Director for approval prior to being submitted to the Planning Commission for final approval. The subdivider shall confer with the Public Utilities Director on allowances for extra capacity in the subdivision sewer that are required for expansion of the sewer system beyond the limits of the subdivision before plans are submitted to the Public Utilities Director. No final plats shall be approved by the Planning Commission until the Public Utilities Director has approved the detail plans and specifications for the sewer. All plans and specifications submitted for approval shall be fully detailed so as to assure conforming and reliable construction, and shall be stamped by a registered professional engineer. The drawings are to conform to City standards. If revisions in either plans, specifications or design are found necessary, the submittal shall be returned to the subdivider for revisions and resubmittal.
(g) Inspections.
(1) All sewer and appurtenant structures shall be inspected during construction installation and repair by the Public Works Director or inspectors assigned by him and responsible to him.
(2) The Public Works Director shall appoint or designate an inspector for periodical or continuous inspection as the type of work may require or as he deems necessary.
(h) Inspection Fees.
(1) Classification. Inspection fees shall be classified as follows:
A. Review of preliminary plans.
B. Continuous and intermittent construction inspection.
C. Supervisory and final construction inspection.
(2) Review of preliminary plans. The fee for review of preliminary plans accompanying the tentative plat shall be included in the fee charged by the Planning Commission for submission of the final plat.
(3) Continuous and intermittent inspection.
A. General. When the extent of work in any project so justifies, the Public Works Director may provide for a full-time inspector for that project from his own forces. Where a project does not require full-time inspection, the Public Works Director may provide for intermittent inspection and may use the inspector for more than one such project.
B. Continuous. The Public Works Director shall send a monthly bill to the contractor for the time spent for inspection. The charge shall be at the hourly rate paid the inspectors by the City plus thirty percent (30%), with a minimum billing of one-half hour. If inspection is required at a time when the inspector is designated to receive overtime pay, the charge shall be at the overtime rate paid the inspector, plus thirty percent (30%) with a minimum billing of one-half hour.
C. Intermittent. Intermittent inspection may be provided when where the Public Works Director may consider this arrangement satisfactory. Charges for intermittent inspection shall be the same as those for continuous inspection based on actual hours of service, including time allowance for travel.
(4) Supervisory and final inspection.
A. Supervisory.
1. The Public Utilities Director may direct that soil tests and laboratory tests of material be made, and the subdivider shall be required to pay directly for any and all costs and charges incurred in having the tests made.
B. Final. Final inspection by the Public Utilities Director shall be made after the subdivider has submitted final as-built plans.
(i) Revisions. During construction, no departure from approved plans and specifications shall be made unless a request for a change is submitted to the Public Utilities Director in writing and approval in writing is obtained.
(j) As-Built Drawings. Editor's Note: This section intentionally left blank.
(k) Easements. The developer shall give the City any easements for future sewers recommended by the Public Utilities Director. Any such easements shall be recorded on the plan, and filed for approval with the Planning Commission. In the event it becomes necessary to construct sewers outside the limits of any platted easement, easements to include the sewer shall be given to the City by separate instrument. All sewers shall be constructed in public easements or rights of way.
(l) Sewer Charges. Charges for connection and use of sanitary sewers in subdivisions shall be made at the rate provided for by the City-wide system. All final plats of subdivisions showing sanitary sewers shall have the following note placed thereon in a conspicuous location. "All sanitary sewers shown on this plat shall be subject to the same service charges and same rates as required for the City-wide system."
(m) Allowances for Larger Pipe Requirements. lf the Director requires that the subdivision sewer or sewers must be larger than the size required to handle the sewage flow from the subdivision, due to expansion of the sewer system beyond the subdivision, in the future, the City shall pay the subdivider the difference in cost for the larger piping materials. Additional installation cost for the larger piping is the responsibility of the subdivider.
(n) Responsibility for Maintenance of Subdivision System. The City shall accept ownership and assume responsibility for the operation and maintenance of the constructed subdivision system upon completion, provided that acceptance of the system has been recommended by the Director after proper inspection and tests. The subdivider shall pay for the entire cost of the sewer unless otherwise provided for in this chapter, including the final inspection of the sewer system prior to acceptance by the City.
(o) Performance Bond. The contractor shall furnish to the City a performance bond of one hundred percent (100%) of the cost of the improvements to insure compliance with approved plans and specifications, and the proper functioning of the sewer and appurtenances. Sewer mains in subdivisions shall be included in the subdivision bonding process.
(p) Maintenance Bond.
(1) The contractor shall furnish to the City a maintenance bond of ten percent (10%) of the cost of the improvements for one year after the performance bond is released to insure proper functioning of the sewer and appurtenances.
(2) If maintenance is required as a result of improper construction and the contractor does not perform the maintenance within ten days or sooner in the event of an emergency of written notification, the City may perform the maintenance and subtract the cost ofthe maintenance from the bond.
