  3. Design Challenges • City’s Acceptance of Final Design Concept • Establishing & Satisfing City &County requirements for industrial use • Tie-ins and interface with City (pump station wells & distribution lines) • Running alignment in congested utility corridors Freescale Semiconductor Chandler Groundwater Pipeline

  4. Design Challenges “An air gap or a reduced pressure principle backflow prevention assembly is recommended at each service connection when the auxiliary water supply is or may be contaminated to a degree that would constitute a health hazard;” • City’s Acceptance of Final Design Concept • Establishing & Satisfing City &County requirements for industrial use • Tie-ins and interface with City (pump station wells & distribution lines) • Running alignment in congested utility corridors Freescale Semiconductor Chandler Groundwater Pipeline
