Southeast Growth Area Water, Wastewater, and Recycled Water Modeling and Analysis
City of Fresno, California

West Yost provided hydraulic modeling, analysis, and model development of recommended backbone potable water, wastewater, and recycled water infrastructure required to serve buildout of the proposed Southeast Growth Area (SEGA) Project located in Fresno, California.


Reclaimed Water Distribution System Project
City of Medford, Oregon

West Yost assisted the City with their development of using treated wastewater for agricultural irrigation. This effort has been in response to increasingly stringent discharge requirements imposed by the Department of Environmental Quality (DEQ) for discharge of effluent to the Rogue River. West Yost developed the facilities plan which recommended that the City further evaluate reclaimed water production to reduce the impact of pending Total Maximum Daily Loads (TMDLs) on the Rogue River.


Recycled Water Hydraulic Model
City of Roseville, California

West Yost provided the City with validation of its recycled water system hydraulic model, which originally was developed by City staff using H2OMAP®. West Yost also provided an extended period model that represents the current operational condition of the recycled water system. West Yost utilized the hydraulic model to evaluate scenarios to optimize the use of recycled water and provided flexibility in the operation of the system for future demands. The resulting work allows operational decisions to be made to reduce wastewater discharges.


Water Recycling Project
City of St. Helena, California

West Yost is assisting the City in the development of the best compliance solution for several outstanding regulatory issues associated with their 0.5 mgd Wastewater Treatment Facility (WWTF), including an evaluation of the City’s water reuse options.


Water and Recycled Water Master Planning
Dublin San Ramon Services District, California

West Yost worked with the Dublin San Ramon Services District (DSRSD) in master planning both its water and recycled water systems, and in the design of water and recycled water facilities. This work included the completion of a comprehensive Water Master Plan update integrating aggressive water conservation and reclaimed water elements. Through water conservation and the identification of reclaimed water use opportunities, the projected future potable water demands were significantly reduced, and therefore infrastructure sizing was also reduced, saving money.


Reuse System Expansion
City of Creswell, Oregon

West Yost designed a major expansion to the City’s effluent reuse program. A three-mile-long force main was designed to deliver water to a newly purchased 215 acre reuse site. A new reclaimed water pump station was designed as part of the treatment plant design. The pipeline included a crossing of Camas Swale Creek for which an Army Corps of Engineers 404 permit and a State Lands Division permit were obtained.
