A. General

1. The equipment manufacturer shall furnish the services of a competent and experienced representative who has complete knowledge of proper operation and maintenance of the equipment to inspect the installed equipment, supervise the initial test run, and to provide instructions to the plant personnel.

The first visit will be for checking and inspecting the equipment after it is installed. The second visit will be to operate and supervise the initial field test.

At least one (1) day shall be allocated solely to the instruction of plant personnel in operation and maintenance of the equipment. This instruction period shall be scheduled at least ten days in advance with the Owner and shall take place prior to plant start-up and acceptance by the Owner. The final copies of operation and maintenance manuals specified in Section 01730: Operation and Maintenance Data must have been delivered to the Engineer prior to scheduling the instruction period with the Owner.

2. Field tests shall not be conducted until such time that the entire installation is complete and ready for testing.

B. Pumps

1. After all pumps have been completely installed, and working under the direction of the Manufacturer, conduct in the presence of the Engineer, such tests as are necessary to indicate that the pumping system operates satisfactorily and meets the conditions of service specified. The factory tests are the basis of equipment efficiency demonstration, the field test shall demonstrate correct mechanical operation after pump start-up. Field tests shall include all pumps included under this section. The Contractor shall supply all labor, equipment and incidentals required to complete the field tests.

11209-13 122313

b. That the units operate without overheating or overloading any parts and without exceeding specified limits for objectionable noise and vibration.

c. That there are no mechanical defects in any of the parts.

d. That the pumps can deliver the specified pressure and quantity (±5% certified curves).

e. That the pumps shall be capable of pumping the specified service liquid.

f. That the pump sensors and controls perform satisfactorily and proper alarm functions.

3. If the pump performance does not meet the Specifications, corrective measures shall be taken or pumps shall be removed and replaced with pumps which satisfy the conditions specified. A 7-day operating period of the pumps will be required before acceptance.

4. Stainless steel pumping units shall show no signs of corrosion upon final acceptance by the Owner.

C. Motors

1. The Contractor shall megger each motor winding before energizing the motor, and, if insulation resistance is found to be low, shall notify the Engineer and shall not energize the motor.

2. The Contractor shall check all motors for correct clearances and alignment and for correct lubrication in accordance with Manufacturer's instructions. The Contractor shall check direction of rotation of all motors and reverse connections if necessary.

3.03 WELL DEVELOPMENT, DISINFECTION, AND CLEARANCE

A. The Contractor shall be responsible for supplying, installing, removal, and restoration of temporary discharge piping required in order to dispose of raw Floridan water during pump installation, testing, development, and disinfection. Temporary piping shall be supplied to convey the water from the end of the raw water main to the concentrate transmission main.

B. After the permanent well pump has been installed, the well shall be developed with the well pump at a flow rate of no less than the design pumping rate for a period of up to 20 hours. The turbidity of the raw water shall be monitored by the Contractor during development. Development shall be considered complete when the turbidities are less than 0.5 NTU for at least an hour based upon measurements taken every ten minutes

11209-14 122313 and the turbidities are not decreasing more than twenty percent from the beginning to end of the hour.

C. After the well has been successfully redeveloped, the Contractor shall disinfect the well, well pump installation, and raw water main. The Contractor shall introduce sufficient chlorine solution into the well, well piping, and raw water main to produce a chlorine residual of 50 mg/L in accordance with AWWA C651 and C654. The Contractor shall submit his procedures for disinfection to the Engineer for review and comment prior to proceeding with disinfection. The chlorine residual shall be measured until it drops to zero, at which time the well shall be pumped to waste for a minimum of 15 minutes and turbidities checked to be less than those specified in 3.03B, the well shall be ready for bacteriological evaluation.

D. The Contractor shall furnish the necessary labor and equipment to assist the City in obtaining daily bacteriological sample for 20 consecutive days. The samples shall be obtained using the permanent pump and taken after 20 to 30 minutes of pumping. If all 20 samples show the absence of coliform bacteria, the Engineer shall submit the results to FDEP and request clearance of the well for service. After receipt of clearance from the FDEP, the Contractor shall connect the well discharge piping to the raw water mains and proceed with final testing of the well installation.

E. If the wells fail the initial bacteriological evaluation, the Contractor shall redisinfect the well in accordance with 3.03C and assist the Owner in obtaining additional bacteriological samples as described in 3.03D, all at no additional cost to the Owner. If the second effort to clear the well fails, the Contractor may request a change order for the additional work required to obtain clearance of the well for service.
