3.2 It is understood that the Town will make power, potable water and sanitary sewer <br />services available for pilot plant use at its' Membrane Water Treatment Plant site. <br />The District will route temporary overhead power cable from the Membrane Water <br />Treatment Plants' main power distribution panel to the pilot plant trailer and cargo <br />container. The District will install buried temporary potable water and drain lines <br />will be buried from the trailers to the connection with the Town's utilities. <br />3.3 Prepare record drawings of the completed pilot plant installations and submit ten <br />(10) paper copies and one electronic copy to the District and the Town. <br />4.0 Task 4- Pilot Plant Equipment Startup and Commissioning <br />4.1 The District and various equipment vendor service technicians will conduct <br />pressure and flow testing of pilot plant components to verify proper operation —in <br />particular the systems operating at pressures greater than 500 psi. Verify calibration <br />of instrumentation and communication with the system monitoring and control <br />system. Once all the equipment is operating properly, begin concentrate treatment <br />testing at a low recovery rate to establish a steady state baseline operating condition. <br />4.2 It is assumed that the Town's treatment plant and peripheral systems are operating <br />in a stable predictable manner such that concentrate production is consistent. <br />4.3 Prepare a Project Start-up and Commissioning Technical Memorandum (TM) <br />documenting the baseline operating conditions. <br />5.0 Task 5- Operate and Monitor Test Scenarios <br />5.1 Upon establishing baseline operating scenarios for each pilot plant process, <br />incrementally increase the recovery, flux rates and other operating parameters in <br />accordance with the Project Work Plan testing plan until the ultimate performance <br />objectives are achieved. Periodic chemical cleaning of plant components and <br />regeneration of the softening resins will be required. <br />5.2 Testing is assumed to be completed over a 4 month period to allow sufficient <br />time (two to three weeks) to evaluate pilot plant process performance and to monitor <br />processes for potential mineral scaling or equipment problems. During this period the <br />Consultants field engineer will visit the site daily to monitor and maintain the <br />equipment. Vendor technicians and District process specialists will periodically visit <br />the site on as needed basis to optimize the treatment process. <br />5.3 If the District determines during the course of testing that the ZLD equipment or <br />configuration is not appropriate or does not meet expectation, the Consultant may <br />terminate the test and recommend alternate treatment strategies for the pilot test.
