grammar and vocabulary + summary for the conclusion

The team came up with six different option solutions. These solutions are about different ideas of locating reservoir, storage tank, pumping station, and emergency pipes in four different areas. These areas are WWTP, between WWTP and Airport, Simpolt, and airport. The team comes up with a decision matrix to rate each one of these elements, such as, reservoir, on each different location. To make it clearer, locating reservoir by WWTP gets different points than locating it by Simpolt. The team rated each one of these elements based on five different criteria, which are cost, energy, water consumption, land, future uses, and quantity. The rating scale was 1-5 worst to best except for the quantity, which is based on the quantity number. The best solution is about pumping the reclaimed water from the WWTP crossing the Portnuef River to a reservoir is located between WWTP and airport. Then from the reservoir again pumping the reclaimed water crossing I-86 to Simplot, and another way from the same reservoir pumping the water directly to the airport and another reservoir located by the airport.

For the best solution, Helal is doing the geotechnical design. First step for the geotechnical design is testing the soil of the reservoir’s land and determining the classification and behavior of the soil. The water content results turns that the water content for the soil at the land we plan to build the reservoir is 26.8 %. This means the soil is not clay, which is good because clay does not allow water to filtrate as easily as other soil types such as sand. Gradation test turns the classification of the soil and the results come to be that the type of soil for the land that we are planning to build the reservoir on is silty sand. This type of soil allows for infiltration, which is the movement of the water into the soil surface. Next step, is to get the size of the reservoir.

Fatimah is doing the hydraulic design selecting the sizes of the pipe are the first step. PVC type pipe schedule 40 is selected. Length, flow rate, and the elevation, and the velocity play a main role in selecting the size, for that it was better to split it to three categories. The first category is from WWTP to the Reservoir; the size of the pipe is 24 inches with a velocity of 3.45 ft./s and flow rate of 10.83cfs. The second category is from the Reservoir to the Airport; the size of the pipe is 14 inches with a velocity of 1.87 ft./s and flow rate of 2.0 cfs. The third category is Reservoir to Simplot; the size of the pipe is 16 inches with a velocity of 2.149 ft./s and flow rate of 3.0 cfs. Reducing the size of the pipe is possible by increasing the velocity. Next step is designing the pumping stations and approximates the pipes.

Caryn is doing the Structural design. The first step in the structural design is about designing support systems for carrying the pipe full of water across the Portneuf River and Interstate 86. For determining the load, two areas were considered. Pipe material is considered the dead load, and the load of the water, which filled the pipe, is the live load. First area is WWTP and Reservoir with a 24 inches PVC pipe; the total load (live load +dead load) is equal to 206.609 lb./ft. The bridge that crosses the Portneuf River near the WWTP does not designed to withstand any additional loading, for that a new support system will be designed. Second area is Reservoir to Simplot; total load comes up to be 143.642 lb./ft. For the overpass that crosses Interstate 86, a new support system will need to be designed to cross over or under Interstate 86.

Zaid is doing the Environmental design. Getting a spreadsheet with all of the data obtained from testing of the effluent currently being discharged into the Portneuf River. The data provided information for pH, temperature, Biochemical Oxygen Demand (BOD), TTS, Volatile Suspended Solids (VSS), EColi, TKN, NH3-N, TDS, Ortho Phosphate, Alkalinity, Final Dissolved Oxygen and Final Outfall grab. We looked at the categories of pH, temperature and BOD to evaluate the state of the treated wastewater. Based on these data, analysis if the content of the reclaimed water meets the uses in each area.
