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

For the last several years, the City of Phoenix has undertaken the task of revising its design standards manual for water and wastewater systems. After much effort and input from City of Phoenix staff, the Development Advisory Board, the Home Builder’s Association, the design engineering community, and various other groups, the revised new Design Standards Manual for Water and Wastewater Systems has been finalized.

As of August 1, 2004 , the new standards will be officially adopted for any new projects in the City of Phoenix . The new Design Standards Manual for Water and Wastewater Systems is available in the Design Standards section of the Phoenix Water Services website.

Until the standards are implemented on August 1, 2004 , we realize projects continue to be submitted to the City for review. So, in order to determine a point at which to require a project to follow 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.
