The Sand Dollar PS consists of three (3) 300 horsepower split case centrifugal pumps operated with variable frequency drives (VFD) to supply the North Padre Island distribution system. At present, only Pumps #2 and #3 are in operation due to Pump #1 currently being repaired due to recent failure. Both Pumps #2 and #3 have been limited at this time to not allow full capacity due to the pumps tripping and drawing excessive amperage. As a result, the Sand Dollar pump station has put the City into an emergency condition as the current pumping capacity available is well below the pump stations rated capacity. The purpose of this task authorization is to provide assistance to the City by performing an assessment of the Sand Dollar pump station to determine the causes of the recent pumping issues that have occurred and enable the City to find a solution to the problem. Under this task authorization, a technical memorandum will be issued to the City detailing the reasons for the issues occurring and recommendation for remedial measures needed in order to resolve the issues. Based on the findings of the assessment, the City will make decisions regarding the future course of action and a separate task authorization may be issued for the implementation of selected remedial measures. SCOPE OF WORK ADDITIONAL SERVICES: Task 0001 —Sand Dollar Pump Station Operational Assessment The Engineer will perform the following: i. Conduct up to two (2) meetings with City Staff and Water System Operators to gather input on the existing condition of the pump station, typical operations, operational difficulties and pumping issues that have occurred. ii. Conduct one (1) site visit to gather field data for existing pump station to include pumps, motors, VFDs,and appurtenances. Pump testing will also be required during the site visit to determine the current output performance for each pump. iii. Review existing data provided by City staff to include SCADA recorded data (to include Coral Vines EST levels). recent water consumption data for North Padre 1 EXHIBIT A C1/�1"1e .1sa 9' �N • ' O A LNV0 • b7 Island distribution system, and AMR data for Nueces County Water District #4 (if available in 5-minute increments for a period of 2-weeks). iv.
