PRESENT: Directors: Morales, Goodrich ABSENT: Patrick Milroy, Operations Manager STAFF: Jeff Noelte, Director of Engineering & Operations; Martha Duran, Sr. Administrative Assistant; Brenda Van Meter, Administrative Assistant; Jason Wolfe, Senior Engineer GUEST(s): 2 PUBLIC COMMENTS There being no written or verbal comments, the public participation section was closed. APPROVE THE MARCH 25, 2019 ENGINEERING AND OPERATIONS COMMITTEE MEETING MINUTES There being no objection to the minutes, the March 25, 2019 minutes were approved as submitted. OPERATIONS REPORT FOR JUNE 2019 Jeff Noelte presented the Operations and Maintenance reports. He reviewed the fact that we have a dedicated staff member that manages the USA program and walked the Directors through the report. Mr. Noelte discussed that we have an annual goal to service hydrants, which is higher some months based on staff availability. Mr. Noelte discussed the Operations Report and pointed out that due to the hydro-generation that we can turn out water and use it to recharge the ground water. He explained that the reason that the sewer was not videoed in March was due to staff being pulled to manage other areas. ENGINEERING UPDATES Sterling Natural Resources Center (SNRC): Mr. Noelte presented the SNRC time lapse picture to show the progress of what is happening at the site. He discussed the concrete walls that are going up and how the walls are being built. Over a thousand yards of concrete have been poured to date. The picture presented Subject to Approval 2 Minutes 7/22/2019 bvm was one of three aeration basins. Mr. Noelte illustrated that baffles will be installed to ensure the water flows through properly. He said by installing the baffles now we can avoid a retrofit later. The membranes will be housed in a separate tank that will allow the water to be housed separately from the pollutants. Plant 134: Mr. Noelte reviewed the changes taking place at Plant 134. He said that sludge builds up on the lagoons. Staff keeps up with it now, but when we expand the amount of water, we produce we will need to find a better way to manage it. We know a lot of people use press management to deal with sludge. Mr. Noelte stated that we need to investigate our options in order to find the best solution, and that a contractor has been secured to do this for us. The contractor will take about four months to evaluate the best solution for dealing with the sludge. Mr. Noelte presented how we are also dealing with TTHM’s at the plant. We do not have the chemistry and the purity at this plant to deal with this. East Valley Water District hired a consultant to help us establish an appropriate treatment plan. Mr. Noelte specified that we want the best fit for our rate payer to find a good effective solution for EVWD. He described how organics come through the water change over time and that other surface water treatment plants also deal with organics. Many use radio activated carbon, but that may not be the best option for us, which is why we are working with a consultant to find the best options for us. Water Source Tank Rehabilitation: Mr. Noelte provided Operations and Engineering’s plan for tank rehabilitation. He said most of our tanks are more than 20 years old. A routine asset management strategy is that you get in and drain in and recoat it, replace things that need to be replaced. East Valley Water District is in the process of securing a contract to begin routinely updating, evaluating, and replacing tanks on an annual basis. Mr. Noelte offered that with the nature of our system, we would want to do this when we are not in high demand. The idea is to increase storage capacity. Director Morales asked about earthquake retrofitting. Mr. Noelte responded and said that the retrofitting is part of the process.

B AC KG R O UN D / AN ALYS IS : T he P ro ductio n Department is res p o ns ib le for all maintenanc e and ins pectio n ac tivities of ap p roximately 40 d ifferent p lants that ho s t wells , b o o s ter p ump s , valves and res ervo irs . T hese p lants req uire a daily visit and visual ins p ection of equip ment to ens ure ac curate water p roduction, water s torage, prop er c hemical dosing, calibrations and sec urity. Minor maintenance o r repairs of eq uipment are comp leted d uring daily ro und s and extensive rep airs are p lanned and bud geted. O ne impo rtant p reventative maintenance ac tivity for the P roduction Dep artment is reservoir ins pec tion. T he District’s reservo irs s tore a to tal of 30 million gallons of water. T hese reservoirs are monitored d aily to ensure adequate water s upply. Ins p ec ting the outs id e of a reservoir is eas y, req uiring an o perato r to s imp ly walk aro und the reservo ir, b e observant and take notes. I ns p ecting the ins id e o f a res ervo ir, however, is a little mo re c hallenging and req uires the o perato r to climb up to the to p o f the reservoir and look inside o f the ac c es s hatch. To get a b etter look and pro p erly inspec t the ins ide of a reservoir, a c ertified S C UBA diver is req uired to get in the water. T hes e efforts are c o ntrac ted o ut by the Distric t. After getting disinfec ted and s p rayed down with c hlorine, the S C UBA d iver c an enter the reservo ir. T he diver uses an under-water c amera recording and ins p ecting all interio r surfac es o f the res ervo ir then p rovid es the Dis tric t with a rep ort and rec ommendation. T he District rec ently c o mpleted a five-year diving ins p ection which will pro vide us with information o n tank rehab ilitation.
