PRESENT: Directors: Morales, Goodrich ABSENT: None STAFF: Jeff Noelte, Director of Engineering and Operations; Patrick Milroy, Operations Manager; Martha Duran, Sr. Administrative Assistant; Brenda Van Meter, Administrative Assistant GUEST(s): None PUBLIC COMMENTS There being no written or verbal comments, the public participation section was closed. APPROVE THE SEPTEMBER 23, 2019 ENGINEERING AND OPERATIONS COMMITTEE MEETING MINUTES The minutes for September 23, 2019 were approved as submitted with one correction. OPERATIONS UPDATE Mr. Milroy provided an update regarding the fencing at Plant 134 and the in-house water main project that is underway. He noted that the fence height has increased from six to eight feet for better protection of the plant. Rocks will be placed along the bottom of the fence once the contractor is completely done installing the fence. A gate with auto openers has been installed. Mr. Milroy stated that we expect the fencing to be complete by the end of the year, with the rocks being added in early January 2020. Mr. Milroy specified the sites located at top of Victoria and Yuma now have new water mains that are six inches in diameter on 28th street. The old water mains were PVC pipe and did not meet industry standards. Fire hydrants are also being added where needed for fire protection. Staff is being rotated to allow cross-training with this process. ENGINEERING UPDATES Mr. Noelte presented Engineering updates to the committee. 2 Minutes 12/02/2019 bvm STERLING NATURAL RESOURCE CENTER (SNRC) Mr. Noelte reported that the concrete continues to be placed for the Influent Pump Station (IPS), Aeration Basins, Membrane Tanks, and Headworks. He stated that the water testing of the IPS went well and the north aeration basin has been successfully completed. Backfilling is underway on the north side of the aeration basins. AUTOMATED METER INSTALLATION (AMI) Mr. Noelte shared that the AMI meters are now in stage four of seven. He stated that Ferguson has been an efficient partner for the District to implement the new meters. MEMBRANE PILOT STUDY A membrane pilot study is in process at Plant 134. Mr. Noelte explained that the District supports the study to the extent that we can provide a site and source water. He said the vendor is funding the study and there is no negative impact for the District. The study allows the District to be a part of new technology development and provides our staff with experience using new materials and equipment. ADJOURN The meeting adjourned at 3:14 p.m. The December 2, 2019 minutes are being approved by Chairman Smith and Director Coats based on the needs of necessity.

B AC KGR O UN D / AN ALYS IS : T he Dis tric t rec ently acc ep ted the trans fer and res pons ib ility o f the Eas t Trunk S ewer Main line that is within the Dis tric t’s s ervic e area. T he s ewer main was previous ly owned and o p erated b y the S an Bernardino Municipal Water Dep artment (S BMW D) and trans fer was comp leted thro ugh a recent quit claim deed fro m S BMW D to Eas t Valley Water Dis tric t. T his trans fer was one of the s tip ulatio ns includ ed in the S ettlement Agreement b etween the Dis tric t and the C ity of S an Bernardino that was exec uted in November 2017. T his large d iameter high flow sewer main is a key as s et to add to the Dis trict's network and will deliver flows to the S terling Natural R es o urc e C enter (S NR C ). T he East Trunk S ewer totals 33,000 linear feet and flows in a north to south fashio n s tarting on Mo untain Avenue, no rth of the 210-freeway, end ing up in the south wes t p o rtion of the Dis trict o n Waterman Avenue. and 6th S treet. Many neighborho ods with s maller sewer mains d ump into the Eas t Trunk S ewer c atego rizing it as a trunk line. N ow that this sewer main is the D istrict's responsibility, E ngineering and O perations have determined it prudent to video inspect and record the current conditions of the main. D istrict staff recently performed 24,000 linear feet of video inspection on the trunk line with diameters ranging in size from 10-inches to 24-inches.T he last 9,000 feet, in the south west portion of the D istrict, is 30-inches and greater in diameter and is too large with volumes too high for D istrict equipment to video inspect. O n J uly 16, 2020, a contractor who specializes in large diameter C C T V completed inspection of the interior of the remaining sewer main. T his was a good learning experience for D istrict staff to work with the contractor to become more familiar with working on trunk line sewers with large diameters and high volumes. T he overall condition of the pipeline is in good working order and the E ast T runk S ewer will be the significant artery directing flows to S N R C for generations to come.

Elec tric al c o nduit and yard p ip ing are being p lac ed . C o ns tructio n p ro gres s pho tos are s hown in Exhibit 1. Eas t S urface Water Treatment P lant Evaluatio n: In O cto b er 2019, findings were p res ented to the Board o f a s implified life cycle c o s t analys is to compare three alternatives fo r providing an ad ditio nal 4 MG D o f water sup p ly c ap acity. T hese alternatives were: c onstruc t a new s urfac e water treatment plant (Eas t S W T P ), c o nstruc t two new groundwater wells , and expand P lant 134. T he find ings ind icated the Eas t S W T P and New G ro und water Wells were wo rthy of further evaluation. S taff cond ucted a more detailed life cycle c o st analys is of the Eas t S W T P and New G ro und water Wells . T he key ques tio n was whether the higher c ap ital cost o f the East S W T P would b e offset b y O &M c o s t b enefits (e.g., lower energy costs s inc e water is produced at a higher elevatio n) and o ther o ngoing benefits (e.g., value of No rth F o rk water in a s econd ary market). T he analys is sho wed the Eas t S W T P and New G ro und water Wells to have s imilar life c yc le c o s ts. C ons eq uently, a preliminary d es ign repo rt will be p repared fo r the East S W T P to ad d definitio n to the p o tential p rojec t s o more realistic cos t es timates c an info rm the d ec is io n-making p ro ces s . T his effort has a bud get o f $175,000 in the c urrent fis cal year. Monitoring for P res s ure S pikes in Dis tributio n S ystem: T he Dis tric t purchas ed and deployed five p res sure gauges capable of meas uring pres s ure 128 times per s ec o nd. T his high-rate monitoring is needed to see if pres s ure spikes (aka water hammer o r p res s ure transients) are o cc urring in our d is tribution s ystem. C o mmon c aus es of p res sure spikes are rapid o p ening/c lo s ing o f valves and the s tarting/s topping of p umps .
