AbstractGreenfield Wastewater Reclamation Plant (GWRP) is located in Gilbert, AZ. This facility is the end-ofline treatment for the wastewater generated within its area and also receives untreated solids from Southeast Water Reclamation Plant (SEWRP), which is a midline treatment facility. The plant is currently reaching the maximum limits of its 24-million gallon per day (MGD) treatment capacity, and within the next two years will need to have its working capacity increased to satisfy the new wastewater demand. Analysis of historical flow profiles indicated that a new design capacity of 38 MGD would satisfy the wastewater demand for approximately 15 to 20 years. With the suggested design and capacity for expansion, it was recommended that the current struvite prevention process is replaced with a magnesium based process that would allow for struvite recovery. Based on the design and capacity recommendations the plant upgrade will cost 55-million USD in base capitol. This is 7-million USD above the theoretical budget of 48-million USD (Schutsky, 2017). The resulting final operation and maintenance costs will be 22-million USD. The upgrades to the plant’s capacity and struvite treatment system are to be implemented by 2020, and will not interfere with the plant’s current operation.
