Producing Safe Drinking Water for TempeWater treatment is the process of cleaning water and making it safe for people to drink. The “natural” water found in the Salt and Verde watersheds is not “pure.” The water picks up substances during its journey through the rivers, lakes, and canal system. These substances-some harmless and others not- include.
The system treats the raw water (from the canals) at the South Tempe Water Treatment Plant and at the Johnny G. Martinez Water Treatment Plant in order to meet safe drinking water standards. These are the steps in the treatment process:

| Transmission and Collection which includes: Maintenance and rehabilitation of distribution system (808 miles water lines)1/12 open to grid now. More opened as needed and able to support. Water that is not consumed by the users must be taken away through the wastewater collection system. This is an engineered system of underground pipes that range in size from six inches in diameter to 48 inches in diameter. This system collects wastewater from all user points and transports it to a treatment site. The ASU Utility Service Section repairs and installs sewer mains, helps control odors in the collection system, repairs and maintains manholes, paints manholes with pesticide paint to help control roach populations in the system, and inspections of the collection system with security teams to record condition ratings for needed repair or replacement purposes..The ASU Utility Service Section is responsible for operating, maintaining, and repairing approximately 496 miles of collection mains including 8,000 manholes. Additional activities include cleaning 550 miles of mains. In reality only 35 miles of mains, and painting around 250 manholes per year are actively maintainedl. | |

Kyrene Water Reclamation Facility
The Kyrene Reclamation Plant was one of the largest membrane wastewater treatment facilities in North America of its kind. The project saw the importance of maintaining this site, and even used some of this technology in its own sites. They tested how best to maintain this site after the fall. The only method that proved reliable was to build an automation support plant that would keep this site running. The project procured the land east of the plant. This site was picked as the railroad tracks were to the west of the site. This site consisted of two building that housed three different machine& tool companies. When the project took over control of the site they used the remodeling of it for more equipment to allow them to setup shop. They build a self contained automation plant to handle the replacement part manufacturing and the fabrication/recycling of the membranes. This site also contains a backup water treatment plant at one tenth the size of the other one. It was meant to be used when the main plant needed to have major repairs. The two project sites were connected underground and the one to the west connected to the city reclamation site. The far west site houses a special engineering team to help get the plant on line and go out and setup mobile treatment plants. It is a sleeper group and was known only to Prime its alt and the South west regional command team. At this time they are still a sleep as far as the computer knows. The plant is in the control of the AZ-3. It is in bad shape as the morrow automation site has not come online it 19 years. The communication alert line that monitored the system was deactivated and as the automation site reads all well and has not reactivated. It seems the system had a flaw when designed and if the system is set to default it disconnects the automation site. The plant seemed to take a hit from lightning some time ago and caused the system to re-boot and be set to default. This plant is running at 14% to16% now. The ASU campus has setup a team to maintain it. I no records of how to support it survived they are just now working out how it works. The system has been back on line for 6 years and they have doubled its output. The plant produces a nice fertilizer and provides some of the cleanest water to be found now days.
The other conventional reclamation plants in Arizona use a Biological Nutrient Removal (BNR) process followed by secondary clarifiers, granular media filters and a disinfection step to meet Arizona Department of Environmental Quality (ADEQ) standards for Class A+ effluent quality. This is what the 202/Dobson plants uses. In the case of the Kyrene plant, th e available 2.55 acre site was too small to accommodate a conventional design. This coupled with the City’s desire for an effluent quality higher than A+ standard led to the membrane technology to replace conventional clarifiers and filters. Membranes were new to the wastewater industry. The membranes used at the Kyrene Plant consist of hollow porous fibers, manufactured by ZENON, with billions of microscopic pores that block passage of solids larger than the pore size. The fibers are assembled into cassettes that are installed in a process tank. A slight vacuum is applied to the fibers to pull treated water (permeate) through the membrane which captures the solids on the membrane surface. Solids are removed from the membranes using a continuous flow of coarse air bubbles in the tank combined with a periodic internal back pulse of water. In addition, the fibers are periodically cleaned in place to maintain optimum flux capacity.
One of the significant technological challenges presented by membranes is the need to screen solids larger than 2 millimeters from the influent waste stream. Solids larger than 2 mm can damage the membrane surfaces. Typical raw wastewater flows have significant concentrations of rags, solids and grease that would quickly blind a screen with openings of 2 mm. The construction team devised a solution consisting of a two stage screen facility with the first screen having openings of 3×15 mm and the second stage with 2 mm diameter openings to meet the membrane manufacturer’s requirements. Over the years the 202/Dobson Plant has been plagued with a microscopic organism known as bryozoa. Bryozoa typically grows in clear water with minimal sunlight. The existing covered final clarifiers, filters and effluent channels provided a perfect environment for bryozoa to form sheets of sticky growth on the walls. Periodically the sheets would slough off the walls and quickly plug the effluent filters. No one knows how the Plant was infected, but the operators soon found there was no cure other than methodically cleaning the filters and waiting for the next outbreak. The decision to use membrane technology was based in part on immunity to bryozoa plugging.
Biological nitrogen removal is accomplished in an anoxic zone located at the head of the treatment basin where an internal mixed liqu or return (IMLR) stream is mixed with raw wastewater influent. In the anoxic zone biological organisms metabolize nitrate in an environment devoid of dissolved oxygen. In the case of Kyrene, the design IMLR rate is five times the influent flow rate. Due to continuous air scouring of the membranes the IMLR stream was expected to have dissolved oxygen concentrations as high as 5 mg/l. In order to minimize adverse impacts to the anoxic zone the construction team devise a way to remove the oxygen from the IMLR stream. The IMLR wet well was oversized to provide adequate detention time for the organisms in the mixed liquor to metabolize the dissolved oxygen to a concentration near zero without the need for chemical addition. In addition, a bypass line was included that allows operations staff to bypass raw wastewater to the IMLR wet well to increase oxygen uptake in the IMLR stream.
Even though membranes had been used in a number of water and wastewater treatmen t facilities it was still a new technology. The durability and length of service life for the hollow fibers was still unknown at the time. The manufacturers claim the membranes would last 20 years in continuous use in wastewater service, but at the time this had yet to be proven through operating experience. The Kyrene plant has proven to be able to last longer then expected, but without the help of the automation plant for the last nine-teen years it was only able to maintain operated unmanned for ten years. It then laid unused for three years till AZ-3 found it and started the work on it.
The automation but the project allowed the plate to produce methane as a byproduct along with a high grade fertilizer. The methane is feed back in to the system to help power it, and at the rate it is operating now to support itself. At full power it pulls from the fusion plant built in to the project site. It has not ran at over 25% for 100 years as it was geared down to save power and ware. The project site’s fusion plant is still at over ½ full in its fusion bottle.
The plans other byproduct is the production of a nitrogen fertilizer. It produced two times the amount the normal plants produce. At full load it would produce 8000 metric tons.
PD Note’s:
In one year the automation plant will come back online to do the twenty year exchange of the membranes and start the repairs needed.
The support team is located in the far eastern building. This site is to be used as the home for the team. Hidden in the servers that support this site is one of the Prime base DR disaster recovery units. This site also housed the team’s vehicle and a very specialized water management support supply site for the Valley. This is a backup to a regional cache but for water related items as it was vital to keep the water flowing in the valley to maintain life. The team has no knowledge of the resupply plant or the backup DR servers. The western site contains the repair shop with a fusion forge and all the tools needed to repair or build the parts needed. The full blue prints on the site are contained in the computers as well as hard copy’s right down to the nuts and bolts level.
Tempe/ASU Power Systems.
Tempe/ASU serves electric customers through a variety of resources including solar, wind, biomass, and geothermal..
Tempe has a 1.5-megawatt (MW) solar facility built using the Sun Catcher concentrating solar-thermal technology. It consist of 60 Sun Catcher dishes and serve as one of the main supports for Tempe and ASU. It was connected to a Southwestern solar system with sites in California and Texas totaling more than 1,600 MW.The system is located in the Tempe Ocotillo Generating Station. N 33° 25.330 W 111° 54.711 12S E 415225 N 3698461 This low-water-use solar dish technology system uses precision mirrors attached to a parabolic dish to concentrate the sun’s energy onto a high-efficiency Engine. Each dish can generate up to 25,000 watts of power. The Sun Catcher requires no water for heating or cooling and a minimal amount of water is required to wash the mirrors and for on-site personnel. The site also has two steam and two combustion turbine units that are capable of generating about 340 megawatts.

The Cross Cut Power Plant is significant as it is the only hydroelectric structure remaining in the Salt River Valley. It is associated with the historic electrification of the valley following the construction of Roosevelt Dam. Two seven-foot penstocks take water from the Arizona Cross Cut Canal, and drops it 112 feet through the Pelton water wheels, which turned Westinghouse generators, generating 11,000 volts. Built by the Bureau of Reclamation, the main use of the electricity is to run water pumps, especially on the Canal. The plant services some of Tempe, including the Hayden Flour Mill. It was build to run off of electric power in the 1920s. The Power Plant is a rectangular (176 ft. by 42 ft.) cast-in-place concrete structure with a gable roof and ridge vents. The rectangular mass is divided into 12 bays (north to south) along the sides and three bays on the sides. The maximum height of the structure is 63 ft. with the main generator floor 22 feet above the tailrace (water exit) grade. The concrete work is detailed with simplified classical motifs, expressed below the frieze panels by a corbelled band course and pilaster capitols. The roof is supported by metal trusses. The windows (one per bay) are metal 4-over-4 light double-hung. The plant is entered from the north with a garage door access from the south. To the east is the switching and transformer building (which measures 89 ft. by 43 ft.) and a shop (16 ft. by 43 ft.). These buildings are of concrete with similar detailing and openings, but with a flat concrete roof. The original equipment remained in the plant, and in 1938 a metal steam generating plant powered by diesel engines was constructed to the northwest. This large building is sheathed in corrugated metal with multi-pane steel-frame awning windows. This plant remains on stand by for over 50 years till after the collapse. It was then brought back on line and has been fought over and in uses till AZ-3 took control of it and all of the Tempe/ASU area.
The wind turbines stretching more than 300 feet into the air and could power more than 15,000 homes at full capacity. The years have not been kind to the systems, anf around half of the systems still run. The others are used as parts to keep them going. The site usually operates around 30% as more in not needed at this time. It as most of the systems is used to power the water system and the ASU campus.
63 megawatts of energy was generated starting in 2010. One megawatt is enough electricity to power about 250 homes at once. Unlike a coal, nuclear or some natural-gas power plants, the wind farm is not expected to produce electricity round-the-clock. It is expected to have about a 25 percent capacity factor,.
When the wind blows it sends electricity from the pla nt, to allow the other facilities to save fuel.
The 24 megawatt (MW) biomass power plant in Tempe uses fuel for the plant derived from wood-waste material trash that has been dried out and animal as well as human waste.. The current fuel inventory at the plant site includes approximately 200,000 tons of waste fuel, approximately equivalent to a two-year supply.
