The paper summarizes the design elements that were incorporated into the City of Bozeman Hyalite/Sourdough Water Treatment Plant to address the cold weather raw water conditions expected, the known wildfire vulnerability within the system, and the susceptibility of the raw water to human impact. A cursory summary of the new water treatment plant p...

This presentation addresses the challenges encountered while building a facility of this size in a cold weather climate in the Rocky Mountains of Montana. The focus will be on the start-up of the facility between ?construction complete? and substantial completion. Specific details of what worked and what didn?t work will be addressed as well as les...

A new filtration water treatment plant (WTP) is required for Basin Creek water in Butte-Silver Bow, MT. The Big Hole water plant struggles to remove an unusually large organic color load during spring, and ecological conditions are making this problem even worse. The Butte-Silver Bow (BSB) water system challenges have DEQ?s attention and BSB will...

The City and County of Butte-Silver Bow (BSB) serves the public water supply system from three surface water sources. An administrative order from the Montana Department of Environmental Quality (DEQ) has resulted in the need to add filtration to the Basin Creek source. Initial efforts focused on site selection, pilot testing, hydraulic analysis, d...

The presentation will use visual aids such as process flow diagrams and three dimensional drawings to describe how the treatment process was designed for ease of operation and the key systems needed for mitigation of risks due to potential wildfires within the watersheds. Pretreatment and temporary systems will be described as they relate to antici...

This presentation addresses the challenges encountered for controlling a truly on-demand WTP. Specific details for the new WTP hydraulics and the new ceramic membranes will be discussed. The focus will be on the start-up of the facility between substantial completion and the first year of operation. Specific details of what worked and what didn?t w...

This presentation addresses the challenges encountered for site selection, design, and construction of a gravity powered on-demand WTP. Specific details for the WTP hydraulics and the new ceramic membranes will be discussed. Engineers, operators, and utility managers will benefit from this presentation by learning about a cutting edge design and o...

As the City of Kennewick, Washington looks to increase the capacity of the membrane water treatment plant (WTP) to its full master planned capacity of 30 MGD, they have identified the need to conduct membrane optimization study with a goal of energy/operation cost savings. This presentation shares historical operational performance of the membrane ...

This case study will describe the options considered for capacity expansion of Saylorville WTP in Des Moines, IA. The facility currently has submerged MF/UF filtration with a side stream RO system for softening. The alternatives analysis used a decision matrix which included capital and life cycle cost as well as non-economic factors to recommend l...
