Water Supply Pumping Equipment Inspection Agreement�
This Agreement entered into by and between ____________________________hereinafter known as the Owner, and Company. hereinafter known as the Company.
The Owner agrees to employ the Company to provide the professional service needed to annually inspect its water supply pumping equipment. This agreement binds the Company to the responsibility for the inspection of the above described water supply pumping equipment.
The Company will annually inspect and perform routine service on the pumping equipment under this agreement beginning in the year______. The pumping equipment will be thoroughly inspected and evaluated to assure that its performance is within reasonable operational condition when compared to the equipment’s original performance standards. The inspection will be limited to a performance evaluation of the pump, motor, motor control system, electrical power supply, water level indicators, check valves and packing or seals when applicable.
The inspection will include, but not be limited to the following:
Determination of pump output (gpm), pressure, and shut-off head. This will be compared to the original design parameters and historical data to evaluate the condition of the pump on the basis of performance. The electrical supply and motor will be evaluated through the measurement of voltage, amperage and a megger check (insulation test) to determine its condition. This information will be compared to design parameters and historical data to evaluate the performance of the electrical components in the pumping system. The motor control section will be operated to verify performance and identify potential operation or maintenance problems. Terminal connections will be checked for arcing and cleaned and tightened if necessary.
Routine service provided for by this agreement includes:
An inspection and adjustment of seals or packing, automatic oilers, screens and vents, thermal overloads, motor protection equipment, line shaft impeller positioning (where needed), check valve integrity, electrical terminal cleaning and adjustment, and lubrication of bearings.
After the system has been inspected, a comprehensive report will be provided to the Owner by the Company detailing the findings of the inspection and evaluation. The report will also indicate recommendations from the Company on preventive and corrective maintenance needed for the pumping equipment. This evaluation describes the conditions observed on the time and date of the inspection only and does not guarantee the continued satisfactory operation of the pumping equipment and related components.
After the report is given to the Owner and recommendations made for needed service or repair, the Company will provide all specialized services needed to carry out any and all repairs to the water supply pumping equipment during the term of this agreement. The cost of the corrective maintenance is not included in the Inspection Agreement between the Owner and the Company, but shall be the responsibility of the Owner. The Company will provide these maintenance services, at the request of the Owner, at established rates for labor minus 10% for having the Inspection Agreement, and competitive unit pricing for components. The Inspection Agreement gives the Owner priority status in an emergency situation. The Company agrees to have a service representative on-site within 24 hours of having been notified by the Owner.
