The City of Henderson is located in the arid climate of southern Nevada's Las Vegas Valley. For the last several years, the City of Henderson has earned the distinction as "the fastest growing city with a population over 100,000." Our population has increased from 48,660 in 1987 to 204,000 as of July 2001 with the majority of this extreme growth occurring in the last eight years.This phenomenal growth has had major impacts on the City's Department of Utility Services, requiring careful financial, technical, and operational planning to keep up with the growth. Currently, we employ over 180 full-time employees who provide water, sewer, and reclaimed water service within a 91 square mile service area and manage a ten-year, $200 million capital improvement plan.Because we have grown from a relatively small utility to a large utility in a short period of time, we have taken a creative and proactive approach to our planning. Our top concern is our ability to maintain our success as a well-managed, respected utility in the years to come. Although we had never performed any "formal" strategic planning, it was clear that a well-crafted strategic plan would play a major role in future success.In the spring of 1999, we contracted with the AWWA QualServe program to conduct an extensive self-assessment, followed by a comprehensive peer review. The intent of utilizing these programs was to get a "snapshot" assessment of how we were performing. The results of the QualServe program determined that the City of Henderson Utility was healthy and had weathered the extreme growth well, but that a formal strategic plan and the development of a continuous improvement program are keys to our continued success. As a municipal utility, we acknowledged that there was room for improvement, at which time we entered into "The Strategic Planning Zone." WEF/AWWA Joint Management 2002The QualServe Peer Review Team believed it would be difficult for us to complete our plan without hiring a facilitator, due to our lack of strategic planning experience and limited staff resources. In the spring of 2000, we contracted with the business-consulting arm of the Black and Veatch Corporation to provide facilitation services. Shortly thereafter, we successfully developed our first detailed strategic plan, consisting of a vision and mission statement and a detailed list of strategic objectives, including the comprehensive action plan necessary to successfully complete each of the strategic objectives. Subsequent assignments were given out to employee teams to help achieve the objectives within the strategic plan.Within several months we faced many challenges in completing the objectives outlined in the plan. These challenges included a lack of staff resources, due to the ongoing demands of growth and the lack of a clear implementation plan. During this same time frame, the City of Henderson began to develop a comprehensive citywide strategic plan through the collaboration of elected officials and all City Departments, including Utility Services.The Departme...
In response to rapid service-area growth, The City of Henderson, Nevada implemented planning efforts for the next expansion of wastewater treatment capacity. As the conclusion of that planning effort prior to facility design, advanced wastewater treatment (AWT) processes were pilot tested for application as a post-biological nutrient removal (BNR) phosphorus removal method to meet strict total maximum daily load (TMDL) limits. The existing solids contact clarifiers and down-flow filters were compared, side-by-side, with pilot inclined plate gravity settler and continuous-backwash up-flow filter technology.The results of the pilot testing indicated that the existing technology requires an alum dose of approximately 70 mg/L to maintain an adequate sludge blanket and produce effective turbidity and phosphorus removal, whether or not a BNR-treated secondary effluent is being treated. The piloted technology allows an alum dosage of approximately 20 mg/L to meet treatment goals on a BNR secondary effluent -a 70 percent savings. The economic evaluation of the two alternatives determined that the plate gravity settler and continuousbackwash up-flow filter treatment process will have at least a 13 percent lower present worth cost compared to installing additional solids contact clarifiers and down-flow filters.
