Implementation of
the City of Phoenix Water Servics Department
Design Standards Manual for
Water and Wastewater Systems

In August 2004, 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.

In order to determine if a project is following the new standards manual, the following criteria have been set:

• Any projects with engineering plans submitted prior to August 1, 2004 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.
