Infrastructure Investments

Infrastructure improvement means investing in the rehabilitation or replacement of aging water and wastewater infrastructure, including pipes, treatment plants, pumps, reservoirs, wells, and conveyance systems. These investments ensure the reliable delivery of the city's drinking water and the effective collection, conveyance, and treatment of wastewater.

Our Capital Improvement Program

The City of Phoenix Water Services Department Capital Improvement Program (CIP) is a multi-year plan for capital projects. These projects maintain safe and reliable water deliveries and removal and treatment of wastewater. Phoenix Water projects make a difference to the future of our city.

Proper management of the CIP ensures we get the maximum value of our customer's rate investment while we work together as Phoenix grows. We take months to identify our public facility and infrastructure needs for our CIP plan. All the projects in the CIP are presented to the Water Services Department Executive Team who discuss each project, prioritize, and decide which ones fit in the CIP for the coming years. Capital projects generally follow this three-phased approach.

  • Assessment

    An assessment analyzes a part of the water or wastewater system to determine the condition and/or remaining life.
  • Design

    A design is the plan on how to repair the condition, from installing a new part to extending the remaining life of an existing part. For example, replacing a water main from the 1950's is a typical design plan.
  • Construction

    Construction is the physical installation of the design, which may include hiring a contractor, purchasing materials, surveying, removing old or damaged infrastructure, installing new or repairing infrastructure, and restoration of the area.

  • Water Usage Fee

    This is the charge for each unit of water that exceeds the amount included in the Base fee.
