During the preliminary design, it was identified that both the Canal and Forebay Pump Stations do not conform to Hydraulic Institute geometric Standards (HI 9.8-2018). Due to reported past vibration and seal failures, it is therefore recommended that a physical laboratory scale model study be performed to ensure that there are no adverse hydraulic conditions present which could impact pump performance adversely during this replacement. The cost for the additional investigation will be a lump sum amount of $68,902.50. We would like to proceed this work as soon as possible to keep the project on schedule. Should you have any questions or require additional information, please feel free to contact me at (713) 208-9463.

CEH has enjoyed working with Ardurra on previous modeling projects. We have extensive experience with pump intakes including numerous vertical pump applications in water treatment facilities. Our lab is fully equipped for this type of project and will fully comply with the ANSI 2018 Hydraulic Institute Standards. INTRODUCTION Ardurra has requested that Clemson Engineering Hydraulics, Inc. (CEH) prepare a proposal to conduct a physical hydraulic model study of the existing Baytown Water Authority WTP Canal and Forebay pump intakes. Both intakes house four (4) pumps with Forebay Pumps 1-4 and Canal Pumps 1-2 each rated at 7,000 gpm and Canal Pump 4 (Bypass Pump) rated at 17,000 gpm. Ardurra is planning to replace all pumps with equal capacity pumps. Given that the intake does not conform to Hydraulic Institute geometric standards, and some reported past vibration and seal failures, a physical model study is being proposed to ensure that there are no adverse conditions present which could impact pump performance SIMULATING BOTH INTAKES Given the differences in pump sizes and the geometry differences between the intakes, both intake structures will be evaluated as separate models with all four pumps simulated in both intakes. DESIGN REVIEW - PROJECT SCHEDULE AND LAB AVAILABILITY With our current backlog we will we can conduct the initial design review and start model design and drawings immediately but a model basin may not be available until late October or early November. CEH anticipated being able to complete the study in 8 to 10 weeks once model basin space is available. As you may be aware, we have recently acquired 60,000-ftz of additional modeling space. This space is now fully operational as shown in the photo below. Photo 1 A Portion of 60,000-ft2 of New Lab Space Immediately Available for This Project MODELING EXPERIENCE CEH has extensive pump station physical modeling experience and has completed over 1000 large scale pump intake models including many cooling tower intakes for Ardurra. The photos below show several recent studies demonstrating our ability to simulate complex upstream geometries, complex piping and large-scale models. The photos below are from the recent models.

All eight pumps will be simulated in detail (four in each intake) 2. Both intake structures will be simulated. The upstream model boundary will be the openings into the intake. 3. Testing will be conducted in accordance with the 2018 HI standards. 4. Modifications will be developed which will not impact the overall foot -print or size of the intake. These modifications may include fillets and splitters, floor cones, curtain walls, baffling, and other similar devices. SCALE SELECTION To obtain accurate results from a model study, there must be dynamic similitude between the model and the prototype. To satisfy this requirement, there must be exact geometric similitude. In addition, the ratio of the dynamic pressures must also be maintained. Strictly satisfying dynamic similitude requires a 1:1 scale model. This is usually not feasible, so some compromise is made. To accomplish this, geometric similarity is maintained and the dominant forces associated with the prototype are determined and maintained between the model and prototype. The primary forces that affect fluid flow are viscosity, surface tension, velocity (inertial), pressure, gravity and elastic forces. In structures with a free surface, such as a pump intake, gravitational and inertial forces are far greater than the viscous and turbulent shear forces. Therefore, when modeling free surface structures, geometric similarity and the ratio of inertial to gravitational forces, or the Froude number, is maintained between the model and prototype. Simply holding the Froude number constant violates the strict definition of dynamic similitude. However, if the model is operated within a high enough range of Reynolds numbers, viscous and surface tension scale effects may be minimized. The 2018 Hydraulic Institute Standards (ANSI 9.8-2018) recommends that the minimum Reynolds number at the bell be greater than 6 x 104. Therefore, when choosing the model scale, it is necessary to ensure that the scaled flow rate will result in a high enough Reynolds number to minimize scale effects. Based on the above discussion, a Froude scaled, undistorted and geometrically similar model with a scale of 1:4 is anticipated for this study (scale to be finalized when additional pump information is made available). This scale will result in Reynolds numbers on the order of 1 x 10' at the suction bell. A scale will be selected that ensures the Reynolds numbers exceed Hydraulic Institute Standards. The final scale will be determined when the detailed pump bell information is made available. PERFORMANCE CRITERIA It is proposed that the following acceptance criteria be used for this model study: 1. No organized free surface or submerged vortices greater than a Type 1 (general rotation) should be permitted at Froude scaled flow rates 2. Pre -swirl should be less than 5-degrees four diameters (per HI) downstream of the pump impeller location. 3. Time averaged velocities within the pump throat should deviate less than 10 percent of the cross -sectional area average velocity 4. Time -varying velocity fluctuations (turbulence) at a point within the pump throat should be less than 10 percent INSTRUMENTATION AND DATA COLLECTION The following data will be collected and recorded for each test: Flow Rate — The total model flow rate will be determined with an ASME standard orifice meter. Individual pump flow rates will be measured with elbow meters calibrated in -situ or other suitable flow meters with an accuracy of +/- 2 percent or better. 2. Water Levels — The water level in the pump sump will be recorded with a point or staff gauge with an accuracy of 3 mm (.01 ft) or better. 3. Vortices — Vortex formation will be visually observed. Dye will be used to aid in the visualization of vortex formation. Digital photographs and video footage will be used to document vortex formation. 4. Velocities — Velocity fluctuations and turbulence levels will be measured in the pump throat of one pump throat of each size. The velocity meter will be capable of measuring the axial component of the flow velocity and will have a repeatability of +/- 2-percent. The velocities will be measured on a constant radius, at 8 points around the pump throat. Pre -Swirl — A swirl meter will be installed four throat diameters (per HI) downstream of the impeller location for each circulating water pump. Each swirl meter consists of 4 straight free -spinning vanes mounted on a shaft with low friction bearings. MODEL LIMITS The upstream model boundary is assumed to be the inlet to each wet well. The downstream model boundary will be the entrance to the pump impeller. The entire intake structure housing the pumps will be simulated. The model head box, floor, and sidewalls will be constructed with waterproof wood. The model pumps, intake piping and pump bells will be fabricated out of clear acrylic up to the impeller location. The additional piping will be fabricated out of PVC pipe. The suction piping will be fabricated from PVC pipe. Valves will be used to control the individual pump flows as well as the total model flow. A pump will be installed downstream of the model pumps to re -circulate flow back to the model head box. Flow straightening devices will be installed as necessary to ensure that flow entering the model head box is uniform. Friction losses within the model limits are negligible compared to form or boundary losses. Therefore, it is assumed that materials mentioned above will be appropriate for model construction. Model design drawings will be prepared and submitted to Ardurra for approval prior to construction. The overall model basin will be constructed with a tolerance of +/- 6.4 model mm (0.25-in). The model pumps will be constructed to within +/- 1.5 model mm (0.06 in). TEST PROGRAM The model testing will be carried out in four phases. The actual test conditions will be determined with additional input from the pump manufacturer, design engineer, and end user. Each phase is described below: I. Baseline tests — Baseline tests will be conducted with the original intake design. It is anticipated that 6 baseline tests will be conducted (for each side), and the data mentioned in the instrumentation and data collection section of this proposal will be collected during each test. The worst -case conditions will be determined during this phase of testing. These tests will be used to determine the nature and severity of hydraulic phenomena occurring within the pump intake structure. 2. Modification Tests — Modification tests will be conducted and modifications will be performed to bring the pump intake within the performance criteria. All proposed modifications would be presented to Ardurra for approval. Approximately 2 weeks have been allocated to modification testing. Changes will be limited to non-structural modifications such as fillets and splitters, floor cones, curtain walls, baffling, and other similar devices that will not impact the overall size and shape of the intakes. 3. Witness Test — Following modification testing, a one -day witness test (in - person or virtual) can be held at Clemson Engineering Hydraulics facility to demonstrate the models with and without the proposed modifications. Preliminary modification drawings will be available at the witness test. Representatives from Ardurra and their clients are encouraged to attend this test. Travel costs associated with Ardurra and their clients attending this test are not included in this proposal. We can also provide an intermediate video in place of a witness test so that the results can be viewed prior to any final testing. 4. Documentation Tests — Following the witness test, it is anticipated that up to 12 documentation tests will be conducted to document the performance of the pump intake with the recommended modifications in place. The cost of evaluating the performance of the intake with the proposed modifications is included in this proposal. REPORTING CEH will prepare a project report containing methodology, procedures, conclusions and recommendations, as well as all data and documentation acquired during the testing for each of the intakes. A draft report will be made available at the witness test. Raw video footage of the testing will be provided in DVD format. SCHEDULE Given our current backlog, CEH anticipates starting modeling in early November and having results near the end of December or early January. The final report will be issued approximately one week after the witness test. CEH will work with Ardurra to ensure all critical deadlines are met and if necessary, revise the schedule to accommodate required due dates. A detailed schedule will be provided once an actual start date has been determined.
