Implementation Guidelines

​​Design Standards Manual for Water and Wastewater Systems

In January 2013, a new Design Standards Manual for Water and Wastewater Systems was finalized.

The new manual is available from the Design Standards section of the Phoenix Water Services website.

To determine if a project is following the new standards manual, the following criteria has been established:

  • Any projects with engineering plans submitted prior to January 30, 2013 will not be required to change to the new standards.

  • If a project has received preliminary site plan approval prior to the implementation of the new standards , but has not submitted engineering plans, the engineering plans can be reviewed under the previous standards upon request to your DSD plan reviewer.

  • If a Planned Community Development (PCD) project that is required to submit a master water and wastewater drainage plan and report has an approved submitted the plan and report prior to the implementation of the new design standards , but has not submitted engineering plans, the engineering plans for any site plan within the PCD can be reviewed under the previous standards upon request to your DSD plan reviewer.
