Complexity begets complexity, and complex plants almost always create their own challenges. When the City of Glendale, Arizona, needed a new water treatment plant, challenge upon challenge existed. The city lacked the needed easements, had a lot to connect, and could not shut down existing systems. Sundt came up with a solution to all of these: undercut the problem. We decided that a complex drilling plan could undercut easement objections, undercut existing systems and serve as the foundation for integrated connections. To make this work, we needed to take a holistic systems approach to project design – so that we created a system capable of handling an expanding population.


Our solution was to deliver a multiple-phased project that included a 10-million-gallon-per-day (MGD) surface water treatment plant (expandable to 40 MGD), eight miles of pipelines ranging from four to 42 inches in diameter, raw water intake and pump station, flocculation systems, clarifiers, granular activated carbon filter beds, a five-million-gallon, below grade concrete reservoir; and a 20 MGD finish water pump station.


The simplicity of this complexity was that later phases, including an electrical switch yard, standby generators, a chemical feed and storage facility, a backwash basin, and drying beds could all be added to the project with simplicity.
