SAN JUAN LATERAL- ISSUES / DESIGN UPDATE

9. Value Planning Update

a. Study completed in 2021

b. Many proposals have already been incorporated

c. Cost-risk analysis did not anticipate the amount of inflation seen the last two years. The

cost-risk analysis will not be updated but the report will instead be finalized with the

information included at the time of the report.

10. San Juan Lateral Intake (aka Reach 1) – Status/Schedule (Reclamation)

a. SJR Intake Pumping Plant Rehab and SJGS Reservoir Modifications

i. Still in process of collecting design data. Designing gate system for both the

intake and return structure for river flows between 500 cfs and 10,000 cfs

(looking at 9’ radial gate paired with different style of gates on either side to

center the radial gate, dual leaf for return). Designers are performing hydraulic

modeling (CFD) of the existing pumping plant to determine feasibility of using

existing plant sump without expansion for 71cfs (existing 56.4 cfs capacity).

Next will perform model of proposed expanded 4-bay plant.

b. Reservoir Sedimentation Analysis

i. April 11, Design Focus Call – Reservoir Sediment Trap/Removal Efficiency –

To determine capability to function as a sediment trap to remove sediment and

provide suitable water the SJLWTP. Find turbidity thresholds for riverside plant

shutdown. Ran Trap Efficiency Estimate Method for variety of scenarios at

different phases. Trap efficiency at peak when reservoir is full, at highest depth,

shortages could limit sedimentation removal and require de-rating the plant or a

plant shutdown with turbidities above a certain level. This would only be a

handful of days over 50 years and not until 2050 timeframe in worst case

scenarios (full demand from EE/CoF). Model and PNM experience resulted in

similar removal percentages (PNM 93.7%, Model 95%).

i. Will use data from Hydraulic Modeling/CFD to run physical model. Physical

model required to analyze pumping plant hydraulic performance. We are

evaluating an intake structure that does not meet the defined parameters of the

pre-configured intake structures as laid out in (ANSI/HI 9.8-2018). When

varying from pre-configured, time-tested, Hydraulic Institute intake designs, a

physical model should be performed. Ensure acceptable uniformity of flow

conditions within the pump intake structure. Prevent vortex formation that may

be detrimental to pump performance and service life. Provide adequate velocity

distribution and minimize velocity fluctuation within the pump bell

d. SJGS Land/Facilities Acquisition Update

Purchase Contract
